It seemed to me that my closer blew a lot of saves this year so I figured I'd compare him to the other closers in the WBA. Turns out he was below average but nowhere near the bottom of the list when it came to the percentage of save opportunities that he blew. Here's the list. The first number is the total number of save opportunities, the second number is the number of blown saves, and the third number is the success percentage.
chen, groove 31- 1 96.8
hollanda, coqui 29- 1 96.6
whitfield, cobras 52- 3 94.2
rousset, folders 34- 2 94.1
escobedo, stars 48- 3 93.8
foong, dolphins 29- 2 92.9
shimizu, jaguars 50- 4 92.0
lobato, flight 35- 3 91.4
ling, palmchats 23- 2 91.3
vargas, meteors 40- 5 87.5
arenos, toucans 30- 5 83.3
valdez, foxes 41- 7 82.9
datini, pharaohs 22- 4 81.8
ono, emeralds 46- 9 80.4
uborevich, fleur-de-lis 36- 8 77.8
werfel, generals 18- 4 77.8
chalcott, falcons 18- 4 77.8
powell, jacks 11- 3 72.7
gardella, aztecs 36-10 72.2
pierre, dragons 14- 4 71.4
It's interesting to me that the top two guys both pitched for last-place teams.
The guy who hurt his team the most, in my estimation, is Gardella of Mexico City. He led the league in blown saves, and he did that for a team that was in playoff contention.
