Jordan Zimmermann has become an extremely reliable starter. In the last three years his ERA has been between 2.94 and 3.25, his WHIP has been between 1.09 and 1.17, and his strikeout rate has been between 18.6% and 19%. Those rate stats along with 12 wins in 2012 resulted in an ADP of 20-25 among starters for Zimmermann prior to the 2013 season. Despite posting similar rate stats, Zimmermann outperformed his 2013 ADP and finished as the 11th most valuable starter according to our valuations thanks to a jump up to 19 wins.
Zimmermann helped himself in the win category by pitching a little deeper into games. He made the same amount of starts in 2012 and 2013, but he threw 17.2 more innings in 2013. That works out to Zimm leaving the game with an average of 1.65 more outs per game. He also got a bit more help with run support as his run support per innings pitched was five runs compared to 4.7 in 2012. So he was leaving later in games and probably leaving with a lead more often. But those improvements aren’t huge and weren’t worth seven extra wins. When you also consider that we’ve only had 42 19+ win seasons in the last decade and that only six pitchers have had back to back 19+ win seasons in that time frame, it’s highly probable that Zimm’s win total will decline in 2014.
Because of the increased win total, Zimmermann is likely to be drafted as more of a top 15 starter as opposed to a top 25 starter like he was last year. But if his win total does indeed decrease, he’s going to have improve in other areas in order to produce a similar value next year and to be worthy of his draft day price. And given the consistency in the rate stats that was detailed above, an improvement in any of those areas may seem unlikely. But I think Zimmermann may have a proverbial ace up his sleeve.
