Grading Shohei Ohtani’s Arsenal

OhtaniSeven months ago I was perusing Amazon and daydreaming of improbable scenarios that might come back to haunt me. I was already the owner of a Canon Vixia HRF700 digital video recorder. The camera’s battery lasts a couple of hours and there is only around 30-60 minutes of recordable material in a given baseball game. I had never needed a spare battery but started running through Murphy’s Law scenarios in my mind. What if I forget to charge it? What if it gets damaged? What if it malfunctions? In an unprecedented move (for me), I did something I never normally have the foresight to do: plan for contingencies. Besides the battery was only $16. F*** it.

Last Friday, I was glad that I did. On Thursday night, I plugged in my Canon and went to bed with dreams of Ohtani sliders inducing ugly swings and misses. Ok, I made up the dream part, but the rest of this story is true. For whatever reason, my camera did not charge. After an ephemeral freak-out moment at the field, I remembered my spare battery. Worth every penny.

The B Squad scrimmage was slated to start at 10:00 AM. Chris Kusiolek (Twitter @calikusiolek) and I arrived early and claimed our seats behind home. This promised to be a mob scene, especially for normally docile B Squad standards. We were soon surrounded by a mix of Japanese media and domestic scouts. The high powered camera to person ratio was extremely high here. I’d estimate there were between 10 and 20 cameramen snapping rapid-fire action shots of Ohtani’s every move.

Let’s finish the background fluff and get to the good stuff.  Were these videos cherry-picked? Of course. I don’t think that diminishes how good Ohtani’s stuff is and how excited we should be to see him pitch this year.

Fastball – 70

The fastball sat 92-94 and touched 96. My 70 grade is more based off his reported high 90s velocity. I suspect we are in the midst of a spring training ramping up phase. The fastball command was in the 55-60 range; It wasn’t elite but certainly better than average and maybe plus. He used it to both sides of the plate and expanded the zone on hitters with two strikes. Ohtani got some natural plane on the fastball due to his height, and he had the ability to run it armside out of the zone.

Slider – 70

Ohtani displayed advanced feel for his slider. He was able to use it to both sides of the plate. It’s worth noting, he was especially comfortable using it to the left side of the plate (batter perspective), whether back-dooring lefties or breaking it back inside on righties. Ranging from 80-85, it had extreme two-plane movement. Ohtani could use it in the zone early in counts or as a put away pitch below the zone with two strikes.

Splitter – 70

From all accounts the splitter is Ohtani’s go-to strikeout pitch. It was in the low 80s and dropped off the table. It enticed hitters into a couple of ugly swings and misses in this game. He used his slider more than the splitter in this outing which causes me to speculate whether he is “saving” his splitter for actual games in an attempt to limit opponent looks at it. Alternatively, have the Angels recommended a change to his pitch mix? I am unsure of the answer and am probably reading into it too much. It was only 2 2/3 innings in a spring training practice after all.

Curveball – 55

There were two or three curves thrown in the game. Ohtani was using it more as a change of pace offering within the zone. It had huge depth and a 12 to 6 shape. He would play with its velocity a bit and it ranged from 71-79. One was taken for a strike in the zone but left up, and I think a major league hitter would have taken advantage. Guys on this B squad were unable to make him pay for it. There was also a ball that slipped out of Ohtani’s hand a flew to the backstop. I believe that was his curve as well. Despite some inconsistency with it today it’s hard to overlook the massive movement on this pitch; I think it plays to above average.

Overall, it’s a nasty bevy of pitches. He didn’t even break out his changeup, which I have heard is 50-grade pitch. It’s not unreasonable to think Ohtani will have three 70-grade pitches, assuming the fastball reaches its previous velocity. With regards to his overall command projection, Ohtani has long levers, but his body control and athleticism are phenomenal. I think his athleticism will enable him to touch 60 grade command as a whole.

Speaking of athleticism, the most underratedly impressive thing I saw him do was leap into the air and almost knock down this comebacker, a ball he had no business in getting a glove on. I think he’s going to be an elite defensive pitcher.

Like with any pitcher, health is an omnipresent concern and with Ohtani’s reported UCL sprain, there is even more risk. If he stays healthy, I see a player who could step in this year and be a number three starter. And it would not surprise me at all to see him produce at a number two level.

The Ohtani storyline will be a fun follow not only for Angels fans but for MLB fans across the country.

2017’s Most Aggressive Base Stealing Teams

In June of 2017, Baseball Savant introduced a new Statcast metric for public consumption. They defined sprint speed as “‘feet per second in a player’s fastest one-second window.’ The Major League average on a ‘max effort’ play is 27 ft/sec, and the max effort range is roughly from 23 ft/sec (poor) to 30 ft/sec (elite). A player must have at least 10 max effort runs to qualify for this leaderboard.”

Now that we have a year’s worth of data, and we are trapped in the middle of a cold, dark offseason, I thought it would be an opportune time to play around with it. Over the last few weeks I sliced, diced, and minced the numbers. One area explored was team sprint speed and its relationship to stolen base attempts. Sprint speed was pulled from the Baseball Savant Leaderboard and stolen base data was downloaded from Baseball Reference.

Team Att.SBO Plus

As a proxy for team aggressiveness I added team stolen bases to caught stealing and divided by stolen base opportunities (plate appearances through which a runner was on first or second with the next base open). SB Att% = (SB+CS)/SBO

The table above shows teams that sent runners most often in their SBOs each of the past three seasons. Light green represents one standard deviation above average and dark green denotes two standard deviations above average. One has to question how much these totals were the result of team aggressiveness and how much they were the result of team personnel. To check I took a weighted average of each player’s sprint speed by respective player’s plate appearances and then added to find team totals. SS=speed in the next table. If you’re curious to see the exact figures I attached my sheet here: SS Weighted Avs

Att.SBO vs SS Rank

Surprisingly, the 2017 Angels attempted steals at the highest rate despite being the second slowest team! The Brewers and Rangers were also quite aggressive despite their below average collective sprint speeds. The implication is these three teams had some sort of organizational edict to test defenses and attempt more steals. On the other hand, the Reds were the tenth fastest team. It’s also worth noting they were the only team to attempt steals at a plus rate (1 STD > AVE) each of the past three seasons.


To make more sense of the team-level numbers, I decided to get granular and look at them on a player level. First, I wanted to see how many players on each team attempted steals at a higher rate than the league average (5.17%), which you can see in the first column of the table below. Then, I wanted to see how many “not fast” players on each team attempted steals more than the league average rate. I did this by introducing a second filter, player sprint speed. The second and third columns show how many players per team were non-elite & below average runners but attempted steals more than the average rate.

For the purpose of this post I defined above average sprint speed as greater than 27 ft/sec and less than 28.3 ft/second. In the sample of 451 players on Baseball Savant’s Sprint Speed Leaderboard, 28.3 ft/sec was one standard deviation greater than average and 27 ft/sec was average. The middle column below shows eight Rangers, six Angels, and six Brewers attempted steals at a greater than average rate while having above average or worse speed. In other words, eight Rangers, six Angles, and six Brewers were non-elite runners but stole at a rate greater than league average anyway.

# Plyrs per team with att per SBO over 5.17

And they were not alone! My efforts monkeying around with filters and subtotals in Excel yielded this table. What does it tell us? Well for one, the Reds were not as aggressive sending runners as their overall SB Att% would suggest. Additionally, you could argue the Red Sox and Diamondbacks belong in the same conversation as the Angels, Brewers, and Rangers. They were willing to send a comparable number of non-elite runners at greater than league average rates.

While useful, this table is imperfect. Notably, it fails to account for magnitude of the SB Att%. In other words, it treats players who barely clear the league average threshold the same as players who are well above average.

The screenshots below display SB Att% by player for the five aforementioned teams plus Cincinnati. I highlighted SB Att% and sprint speed columns to add some meaning to the figures. It is intended to help visualize whether players attempted steals at a rate commensurate with their speed. The darker the green, the further from the mean. For example, Ryan Braun’s sprint speed cell is white (below average), but his SB Att% is green (over a standard deviation greater than average) so he attempted more steals than his sprint speed would suggest.

Color Coding Explained

For those curious I attached my full spreadsheet. There are two tabs which show SS vs SB Att%: One for a sample of 451 and another for a sample of 491. The second tab adds extra lines for players who played for multiple teams. Sprint Speed vs SB Att%

I made observations on each of the six teams from the slideshow in the blurbs below:

Arizona Diamondbacks – Micro-level, Ketel Marte only attempted steals in 3.85% of his SBOs, a below average rate, despite ranking 29/451 in sprint speed. He should see an increase in his stolen base attempts to at least the above average range next season. Macro-level, the team was less aggressive than I thought. They were the sixth fastest team on my weighted average sprint speed sheet. And they had five players who ran less than their sprint speed may imply. The large number of Diamondbacks attempting to steal at a high rate seems to be due to their roster construction rather than organizational tendencies. I.e. their roster was littered with above average sprint speed players.

Boston Red Sox – I would classify the Red Sox as somewhat aggressive. They were willing to send three above average runners, Benintendi, Betts, and Nunez at well above average rates. They were also “sneaky aggressive” in the sense they sent below average runners Vazquez and Chris Young at above average rates. They should consider sending Bogaerts more often. Not only does his speed indicate he is capable of it, he was only caught stealing once in 16 attempts (94% success rate).

Cincinnati Reds – How does a team with the fourth highest stolen base attempt rate (shown in first table) have only three runners attempt steals at an above average rate? Billy f****** Hamilton. That’s how. He attempted steals an absurd 33.33% of the time in his 216 stolen base opportunities last year. Simply silly. I want to know how many of his attempts included pitch outs. Billy (yes we are on a first name basis) and to a lesser degree Jose Peraza were complete anomalies on this list, and their rates heavily skewed the Reds data. Cincinnati as a whole is firmly in the non-aggressive bucket.

Los Angeles Angels – The Angels table was revealing. All of their eight fastest runners attempted more steals than their speed may suggest. None of their 11 slowest runners attempted more steals than expected. This helps to explain how they could simultaneously attempt the steals at the highest rate while having the second slowest roster. In essence, they were selectively aggressive, stealing more often than expected with above average runners and making little to no effort with below average runners. On a player level, I found it surprising that neither Cameron Maybin nor Ben Revere cleared the plus threshold for sprint speed (1 STD > AVE). However! (S.A.S. voice) They attempted steals at an elite rate (3 STD > AVE).

Milwaukee Brewers – This is a run happy team. Seven players ran more than expected based on their sprint speed, two of whom, Ryan Braun and Domingo Santana sported average or worse sprint speed. Jonathan Villar attempted steals three STDs over the league average rate with merely above average sprint speed.

Texas Rangers – Perhaps the most aggressive team in MLB, they sent some below average runners at above average rates, and they sent above average runners at well above average rates. Delino Deshields was their only real burner, but that didn’t stop them from sending eight other players at an above average rate, which was the second most in the league. (Shown in the second table, first column)

For fantasy players it would be wise to keep an eye on offseason acquisitions by the Rangers, Brewers, and Angels. These players are liable to see increase in their stolen bases in 2018. To what degree? This will be tackled in a future post. Also on tap, who were the least aggressive teams and what we can learn from their data?

A few notes on the information from the slide show:

*Many Detailed Statistics are based on play-by-play accounts accumulated by RetroSheet. These totals may be incomplete – (Copied verbatim from Baseball Reference). This is referring to the asterisks next to player names.

**No players in the sprint speed data set are greater than three standard deviations from the mean. That does not mean Buxton, Hamilton etc. are not 80 runners on the scouting scale. It just means the distribution for sprint speeds does not follow a normal curve.

***Not every player was available on the Sprint Speed Leaderboard, limiting our sample to 451, which is why the average SB Att% of 5.01% differs from the overall league at 5.17%.

10/11/17, 10/12/17 Arizona Fall League Notes

10/12/17 AFL Notes

DJ Snelten (LHP) Angels – Watching Snelten, I became fixated on his somewhat robotic delivery, which resembles a less extreme version of Alex Wood. He lifts his right leg to create deception as he shifts his center of mass forward toward the plate. Once everything is moving, his arm whips around from behind. His fastball is in the low 90s, and his second offering is a high 70s curveball. I think he profiles as an org guy.

10/11/17 AFL Notes

Scott Squier (RHP) Miami Marlins – The Marlins drafted Squier in 2014’s 16th round out of the University of Hawaii (Manoa). In a tweet I described Squier as a “kitchen sink guy”, which is quickly becoming one of my favorite cliches. There seem to be a lot of guys like this. They don’t have overpowering stuff, but they can keep hitters off balance by attacking with an array of pitches at different velocity bands and movements. The fast ball is fringey. It sits 90-92 and sometimes can get to 93. His slider is in the low 80s and may be his best pitch. The curve was 72-75 and was maybe a 45. On separate days I wrote in my notes “85 change (moves arm side)” and 88 “(2seam? moves arm side)”. It’s unclear to me whether or not these are different pitches. Either way, this feels like a swingman profile that will probably bounce back and forth from AAA to the majors and serve as organizational depth.

Miguel Del Pozo (LHP) Miami Marlins – Del Pozo primarily threw fastballs in this game. It was in the low 90s with a cutting action that ran in on RHHs that should result in some weak contact. Del Pozo also showed a curve in the high 70s that looked roughly average.



10/4/17-10/5/17 Instructs Notes

10/05/17 – Giants at Angels – Backfields next to Tempe Diablo Stadium

Trent Deveaux (OF) Los Angeles Angels – Deveaux smashed a triple to left and reached third in 11.70 seconds. It was a thing of beauty. He also made some circuitous routes defensively. One fly ball sticks out in my mind because he “got turned around” and made a last second adjustment to come down with it. I like his aggressiveness on the base paths, but it can border on reckless. He slid head first into home despite a teammate motioning for him to come home standing.

I found this article which gives some context to home to third times

10/04/17  Giants at Rockies –  Field R1 directly south of Salt River Field

Jacob Gonzalez (3B) San Francisco Giants – The son of former Diamondbacks star Luis Gonzalez is still learning to recognize pro-caliber breaking stuff. Scouts opined he has looked somewhat raw at the plate, and he displayed occasionally stiff movements defensively.

Diego Rincones (OF) San Francisco Giants – Rincones has an uncanny ability to hit. There was very little swing and miss in my looks. And there is good bat control in this one (spoken like a true Jedi). I am hoping to see him another couple of times before the end of fall.
