Trevor May and First Pitch Strikes

Last season in New Britain, I watched 4 or 5 of Trevor May's starts. I'm still higher on him than most people are, because a few things became apparent to me after watching him -- all of which are fixable (to a degree, anyway):

1) The defense behind him was sometimes lousy (I'm looking specifically at the left side of the infield -- Danny Santana and Miguel Sano), leading to extra pitches made and extra batters faced to get the job done;
2) Control issues plagued May, despite the fact that his walks/9 decreased somewhat; and
3) He didn't get ahead of batters often enough, thus forcing him to work from behind in the count too often. It's that last item that I want to focus on in this post.

(This is the condensed version of this story, believe it or not. Supersized version -- more stats and explanation -- available at Twins Fan From Afar)

Unfortunately, there's no data tracking first pitch strikes for minor league pitchers, like there is for major leaguers. But because this interested me, I decided to go through May's starts, game-by-game using Gameday so I could view what happened in each at-bat. This took a while, as you can imagine. Trevor May started 27 games for the Rock Cats in 2013, but no data was available for 2 starts. Accordingly, I compiled data the remaining 25 games. Here are my findings: Trevor May threw a first-pitch strike to 52.9% of batters he faced for New Britain in 2013. Yes, good that it's over 50%, but it is by no means an encouraging number.

MLB DATA
What's an average first pitch strike percentage in the majors? 59 or 60 percent. May, then, is well below. Does that matter?

Over 15,000 MLB plate appearances in the 2013 season (same source as previous link), hitters that get ahead 1-0 have a .269/.383./.442 slash line, while hitters that fall behind 0-1 have a .221/.261/.341 slash line. That ends up being a pretty huge difference over the course of a single game, let alone an entire season. Now, I'm not suggesting that May (or any other pitcher) should just groove the first pitch of every at-bat, but it's also important to note that only 7.3 percent of those first pitch strikes turned into hits.

Fangraphs also tracks the first pitch strikes in baseball. Here's the list for 2013's top first-pitch strike hurlers. The Top 30 are by no means full of all-stars, but is a list of generally solid pitchers. Read the list for yourself, but just for fun here are the Top 5: Patrick Corbin (70.2); Cliff Lee (68.5); David Price (67.7); Jordan Zimmerman (66.9); Ervin Santana (65.9). Other notables in the Top 30 include Bronson Arroyo, Clayton Kershaw, Justin Verlander, CC Sabathia, Adam Wainwright, Max Scherzer, Matt Harvey, John Lackey, Cole Hamels and Chris Sale. Those players are all over 62 percent.

MAY IN DEPTH
With that background, let's examine May. Here's a rough breakdown of his 2013 season with respect to first pitch strikes. There were 2 games with first pitch strike percentages in the 30s; 6 games with first pitch strike percentages in the 40s; 13 games with first pitch strike percentages in the 50s; and 4 games with first pitch strike percentages in the 60s. Additionally, May had 11 quality starts in 2013 (meaning at least 6 innings pitched and 3 or fewer earned runs). Of those 11 starts, May had 50% or higher first pitch strikes in 9 of those games.

But there's not necessarily a magic correlation for May between first pitch strikes and dominant performances. May's most efficient performance -- in terms of first pitch strikes -- 67.8%, was in a 5 inning, 4 earned run performance in which he gave up 5 hits and walked 3 batters, proving that strike 1 isn't always effective when you are very hittable on the night and are still walking batters.

Trevor May is an interesting case. Maybe he's at his best when he's throwing first pitch strikes somewhere in the 50s? Let's separate the high 50s from the low 50s, just for fun: When May throws first pitch strikes 55-59 percent of the time, he averages 6.57 innings pitched for those starts. That covered 46 innings and May had a 1.56 ERA. Now for the low 50s -- 50-54 percent first pitch strikes. In those starts, May averaged 5 and 1/3 innings pitched. That covered 42 innings and May had a 4.29 ERA. Incidentally, in those games where he was at or above 60 percent first pitch strikes, May's ERA was 7.25.

I think there are 2 takeaways here. The first is that May needs to do a better job getting ahead of hitters. He's wasting pitches, is not maximizing his efficiency, and is allowing (approximately) 5-7 percent of batters to gain an unnecessary edge over him. The second is that perhaps, for May, having a first strike percentage of 65 or 70 percent of the time (like Corbin, Lee, or Price) isn't optimal. Every pitcher is different, and May has to find out what works for him. When he was grooving first pitch strikes last season, May was a little too hittable, too predictable perhaps.

I don't expect Trevor May will be a #1 or #2 starter on the next Twins playoff team. I do, however, see him as a reliable starter who can strike out double digits in a game -- keep in mind he did lead the Eastern League in strikeouts last season. But in order to get to that level, I see reducing walks, putting hitters away and getting ahead in the count more consistently as the three major (and interrelated) things standing in his May's way.
