When Curtis Granderson exploded out of the gate early in the season I analyzed his performance and concluded that it wasn’t sustainable. At the time his ISO was higher than what Alex Rodriguez had posted in 2007, suggesting that his power was due to wain. A bit later on in the season, I followed up on the prediction and concluded that I was correct, Granderson’s ISO had indeed come down and he was struggling. Where does Granderson stand now?
I am happy to report that this is the most sustainable Curtis’ performance has been all season. After last night’s game he’s batting .274/.366/.571. He was batting .270/.339/.622 when I first examined him in May, with an unsustainable .352 ISO and .263/.337/.570 when I followed up again in June. His numbers have improved across the board since that second check up. Most importantly, he’s picked up .029 points of OBP. That’s a big jump and he brought his AVG and SLG up (just a bit) in the process. While his SLG has come down tremendously from where he was, his current line is preferable for the long haul. His ISO of .297 is still amazing, but also sustainable for the remainder of the season given the way Granderson is playing.
It would be an understatement to say that Granderson’s performance to date was unexpected after his mostly frustrating 2010, but this is exceeding even the most optimistic projections of what Curtis would do. So far this is his best season, better even than his .395 wOBA 2007 when he hit .302/.361/.552. While earlier in the season Curtis was sticking out for all the home runs he was hitting, now he has settled into an all around groove, still hitting for power, but also getting on base in other ways. The sum total is that Curtis has been the best Yankee not named CC Sabathia from start to finish this year. As it stands, his .400 wOBA leads the team, and his 4.5 fWAR is better than his season totals from 2010, 2009 and 2008. Austin who?
