"How can I search the database to find out which player in MLB history has WON the most games (that is, the player actually appeared in the game as pitcher, batter, DH, pinch runner, etc) when his team won that game), and conversely, which player in MLB history has LOST the most number of games."
While PI doesn't have the ability to search for this information for all of MLB history, we can use it to search since 1954. To do this use the "Batting Gamelog Finder", select Team: "Win" and search for "players w/ games in career". This yields the following results:
With his 1-4 tonight, Joe Mauer's batting average dropped to .366, an excellent average, but no longer the all-time best for a catcher (who qualified for the batting title). With 4 games left to the season, Mauer has fallen behind Babe Phelps, who hit .367 for the Dodgers in 1936. Of course, the batting title qualifications were different then and Phelps only had 349 PA in his signature season. If we raise the bar a bit, Mauer only needs to stay above the .362 that was recorded by Bill Dickey in 1936 and matched by Mike Piazza in 1997. Here are the all time BA leaders among players who qualified for the batting title and played at least 50% of their games at catcher (does not include tonight's game, but I'm leaving Mauer 2009 in for comparative purposes):
I'm getting ready for the postseason and I've cleaned up the presentation of the batter vs. pitcher numbers to include a line for the playoffs along with a total line for the regular season and also for regular and postseason.
MGL over at The Book flags a comment by Michael Kay about splits being more likely in double-headers than in back-to-back games as being idiot speak. MGL doesn't back up his comments with numbers, but we'll do the heavy lifting for him here.
Now I look at all cases where two teams played on date N and date N+1. This will include a four-game series on consecutive days 3 separate times. b2b = Back-to-back
I'm not sure why the home team picks up the advantage in the doubleheader (about 1%), perhaps it is because they get to dictate the pitching matchups, or maybe fatiguing situations increases the advantage of playing at home, noise?
With the playoffs quickly approaching, I got curious to see the list of players to lead off a post-season game with a home run. This was done using the Post-season Batting Event Finder.
Lots and lots of good players populate this list, both the batters and pitchers.
I checked the record of the teams in these games. Here are the outcomes of the 22 games (from the point of view of the team hitting the leadoff HR) as you read down the column above.
LWLWWWLWWLWWWWWLWLWWWW
So that's a record of 16-6 (.727) in those 22 games. Not too surprising--with run-scoring at a premium in the playoffs, single runs have a bigger impact on the outcome.
A few other tidbits:
There is one series--the 2007 ALDS--that appears twice here, with the Yankees' Johnny Damon and the Indians' Grady Sizemore both leading off different games in that series with homers. The Indians won both games, as well as the series.
Just 1 out of these 22 games was Game 1 of its series. That's a little surprising, although so many Game 1's are pitched by aces that it's not too surprising.
Finally, I would remiss if I didn't mention how much more common the leadoff HR has become, with more than half of these games coming since the 1990s. While there are more playoff games now thanks to the extra layers of playoffs (meaning more total playoff games per year and hence more chances for leadoff HR) the more recent era is over-represented, thanks to the increased overall prevelance of home runs in the game.
