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 . . .

Another young fan was struck by a foul ball, this time at Guaranteed Rate Field

ESPN reports via the Associated Press that a young boy was struck by a line drive foul ball but was not seriously injured during Sunday afternoon’s game against the Royals. The boy and a woman were escorted by a first aid crew to the concourse area and the boy was later eating ice cream in a luxury suite.

A woman was struck in the face by a foul ball also on the first base side at Guaranteed Rate Field on Friday, but she didn’t request medical assistance.

Last week, a young fan at Yankee Stadium was hit by a line drive foul ball, which motivated several teams to commit to extending protective netting at their ballparks. The Yankees, strangely, were not among them. Nor were the White Sox.

Losses by the Cardinals to the Pirates and the Brewers to the Cubs on Sunday clinched an NL Wild Card berth for the Diamondbacks. Their walk-off, 3-2 win over the Marlins earned them hosting rights for the Wild Card game.

The D-Backs, now 90-66, trailed the Marlins 2-1 going into the bottom of the eighth. Daniel Descalso tied the game at two apiece with an RBI single off of Brad Ziegler. Second half hero J.D. Martinez secured the win with a walk-off RBI single in the bottom of the ninth against Javy Guerra.

The Rockies beat the Padres on Sunday to increase their lead over the Brewers (+2) and Cardinals (+2.5) for the second Wild Card slot. One of these three teams will visit Arizona for the Wild Card game.

The Diamondbacks are back in the playoffs for the first time since 2011, when they lost the Division Series in five games to the Brewers.
