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 . . .

Padres sign Aaron Loup to a one-year deal

Free agent lefty reliever Aaron Loup has been given a locker in the Padres’ clubhouse, AJ Cassavell of MLB.com reported Sunday. Per MLB Network’s Jon Heyman, Loup received a one-year MLB deal with a club option for 2020. The Padres will shift right-hander Garrett Richards to the 60-day injured list to make room on the 40-man roster.

Loup, 31, began the 2018 season with the Blue Jays and was traded to the Phillies for minor league right-hander Jacob Waguespack at the midseason deadline. The veteran left-hander pitched just two innings in Philadelphia before hitting the injured list with a forearm strain and returned for a handful of appearances at the end of the year, bringing him up to a 4.54 ERA, 3.2 BB/9, 10.0 SO/9, and 0.3 fWAR across 39 2/3 combined innings.

Assuming health issues don’t complicate his next campaign in San Diego, Loup will be added to the bullpen alongside fellow left-handers Matt Strahm and José Castillo (with the possible late addition of southpaw reliever Brad Wieck, who underwent surgery for testicular cancer earlier this year). There are worse places to be — according to FanGraphs, the Padres’ ‘pen jumped from second-worst in 2017 to second-best in the league with a cumulative 3.53 ERA, 3.31 FIP, and 8.7 fWAR in 2018.
