Baseball players do not do the whole game theory thing

Leave a comment

Apparently baseball players throw too many fastballs.  It will take smarter people than I am to figure out if this Means Something or it’s merely interesting.  It’s been a long day, however, and at this point interesting is enough for me:

In the case of baseball, we observe every pitch thrown in the major
leagues over the period 2002-2006 – a total of more than 3 million
pitches. For football, we observe every play in the National Football League for the years 2001-2005 – over 125,000 plays . . . The results obtained from analyzing the football and baseball data are
quite similar. In both cases, we find clear deviations from minimax
play, as evidenced by a failure to equalize expected payoffs across
different actions played as part of mixed strategies, and with respect
to negative serial correlation in actions . . .  In baseball, pitchers appear to throw too many fastballs,
i.e., batters systematically have better outcomes when thrown fastballs
versus any other type of pitch.

Game theory, schmame theory. Maybe ballplayers just want to give him the heat and announce their presence with authority. Didja ever think of that? And maybe those suckers simply teed off on ’em like they knew they were gonna throw a fastball.

Oh . . .

Matt Breen of the Philadelphia Inquirer reports that Nick Pivetta will rejoin the Phillies’ rotation, starting Tuesday’s series opener at home against the Cardinals. Vince Velasquez will remain in the bullpen.

Pivetta, 26, allowed 17 earned runs on 31 hits and eight walks with 16 strikeouts in 18 1/3 innings across his first four starts of the season. The performance resulted in a demotion to Triple-A Lehigh Valley. In six starts there, Pivetta had a much better 3.41 ERA with a 50/20 K/BB ratio in 37 innings of work.

Velasquez, 26, was solid as a starter, posting a 3.99 ERA across six starts. However, he averaged under five innings and 92 pitches per start. The right-hander tossed two scoreless innings out of the bullpen on Friday against the Brewers but was torched for four runs in two-thirds of an inning on Sunday. Mixed results, to say the least. The Phillies are trying to do what they can with their bullpen, currently missing David Robertson, Tommy Hunter, Pat Neshek, and Vìctor Arano.
