Playing for the Rancho Cucamonga Quakes, Bob Zimmermann was at his best from the windup. He limited the leadoff batter of an inning to a .188 average against and with surrendered just 24 hits in 117 opponents at bats with the bases empty. Those numbers were far below his season average of .229 against.
As the team's primary closer, where he shut the door effectively in 17 games, Zimmermann did have to enter the game with runners on base. His success in that area was sporadic as the opposition hit .257 with runners on base.
Closer or bridge?
While the number of times he entered the game in the ninth inning dwarfed his eighth inning chances, the right-hander was dominant when he was called upon to perform in frame eight.
Zimmermann allowed just three hits in 37 at bats in eighth inning work. Ironically, nearly all of that work came when he also worked the ninth inning.
In the 14 games that he worked more than one inning, he allowed just two earned runs. Goose Gossage would be proud.
After a slow start to the season where he allowed eight runs in his first 10.2 innings, the now 24-year old gave up eight earned runs over the next three months – spanning 34 innings.
During that time, Zimmermann held the opposition to a .198 average, giving up 24 hits. He also struck out 43.
Zimmermann gave up three homers on the year in 59.2 innings of work and all were served up to left-handed hitters. In fact, lefties had a batting average that was 84 points higher off him than righties (.276 to .192).
In 22 less at bats off Zimmermann, left-handed hitters notched four more hits and 16 of the 22 earned runs that crossed the plate were courtesy of a left-handed bat knocking them in.
Zimmermann also walked on of every 5.7 left-handed hitters and one out of every 21 right-handed hitters.
