|It took a while for Joe Torre to trust him in important situations, but eventually [G]uo saw regular use in a season that left him with a 2.14 ERA (199 ERA+), 96 strikeouts against 84 baserunners in 80 innings, and no trips to the disabled list.|
An ERA+ of 199 are you kidding me? That's a great feat for a 26 year old pitcher. One of the best in the last 20 years I'd guess. Well, using B-Ref, I performed a quick query of the last 20 years, with pitchers having thrown 80+ innings in their age 26 season. The results put Guo's 2008 ERA+ as #10 on the list. Click here to see the Baseball-Ref query and the complete list of best ERA+ seasons as a 26 year old. And if you filter by only LHP, Guo shoots up to #2 on the list only behind J.C. Romero's amazing 2002 season with an 236 ERA+. Guo is slated to be the setup man and likely backup closer should anything happen to Broxton. With that the case, I'd expect Guo to cherry pick atleast a half a dozen or so saves this year.
