Fun with numbers

Posted by: Chad Jennings - Posted in Misc on Jan 13, 2010 Print This Post Print This Post | Email This Post Email This Post

A lot of these statistics mean absolutely nothing, but I wound up looking through some of the Yankees relievers splits on and thought I’d post some of the numbers. Again, most of these are just curious groups of stats that don’t have much real meaning in the course of a baseball season. What can I say? On slow days like this, I sometimes click aimlessly through baseballreference for an hour. That site fascinates me.

Make him the lefty specialist
Damaso Marte’s career numbers against left-handed hitters: .197/.294/.287
Mariano Rivera’s career numbers against left-handed hitters: .206/.256/.261

Earning the losses
Mariano Rivera’s career stats are basically a series of 1s and 2s. Nothing but low ERAs and low opponents batting averages, but it does seem that he’s earned his losses.
In games when Rivera got the save: .163/.207/.199 — 0.64 ERA
In games when Rivera took the loss: .446/.508/.750 — 16.08 ERA
The difference of course, is that Rivera has 526 saves and only 52 losses.

First pitch matters
Dave Robertson has faced 322 batters in his big league career. Twenty three of those at-bats ended after one pitch. The other 299 lasted at least two pitches.
In 154 at-bats when Robertson fell behind 1-0 
31 walks, 40 strikeouts, .248 batting average
In 145 at-bats when he went ahead 0-1
7 walks, 59 strikeouts, .203 batting average 

If you can’t beat him, trade for him
There are nine teams Chad Gaudin has faced at least 10 times in his career.
Los Angeles Angels, 19 games, 5.40 ERA
Texas Rangers, 21 games, 5.37 ERA
Cleveland Indians, 11 games, 5.12 ERA
Seattle Mariners, 15 games, 4.82 ERA
Toronto Blue Jays, 14 games, 4.22 ERA
Kansas City Royals, 12 games, 2.86 ERA
San Francisco Giants, 11 games, 2.76 ERA
Boston Red Sox, 15 games, 2.64 ERA
New York Yankees, 10 games, 1.96 ERA

The opposite of A.J. Burnett
Mark Melancon pitching to Jorge Posada: .163/.308/.233 — 8 Ks, 5 BB
Mark Melancon pitching to Jose Molina: .333/.529/.500 — 2 Ks, 5 BB

The later the better
Alfredo Aceves actually has pretty good numbers the few times he’s pitched the first five innings of a ballgame, but with his role primarily out of the bullpen, he’s generally gotten better and better as the game’s gotten later and later.
Sixth inning: .284/.302/.431
Seventh inning: .293/.361/.480
Eighth inning: .214/.244/.333
Ninth inning: .077/.143/.308
Extra innings: .063/.118/.063

Keep him in the rotation
Make Andy Pettitte a lefty specialist at some point? Maybe not. In his career, Pettitte has actually allowed a higher batting average against left-handed hitters (.271) than against right-handed hitters (.270). Last year, lefties hit a whopping .282 against him.
