Team W/L for each starter
Posted by Andy on August 30, 2007
It's not hard to see which pitchers are the leaders are in wins, losses, and W-L% for any given period. I have gone ahead and calculated something a bit different: team wins and losses for all starts by each pitcher. So that basically takes all no-decisions for each starter and adds them to their win total if the team ending up winning the game, and adds them to their loss total if the team lost.
This stat is pretty easy to see for any individual player. For example, if you check out Bert Blyleven's gamelogs for 1979, you can see that while Blyleven himself earned a 12 and 5 record in 37 starts, the Pirates actually went 23-14 in Blyleven's starts.
I went ahead and got the totals for all starts by each pitcher since 1997, split based on whether the team won or lost. This is really easy to do. Go to the PI Pitching Game Finder, set team W (or team L) on the left, click the bubble for role of Starter, and then sort by Players with games in career. Doing this twice (once for wins and once for losses) generates two long lists. I put those lists into Excel, did alphabetical sorting, and eliminated players who didn't have at least one team win and one team loss. From there, I could calculate leaders by total and percentage.
