Reader George S. wrote in to ask about Curtis Granderson. Much has been made of "The Grandyman"'s new-found power.
To illustrate what George is talking about, check out Granderson's game logs since August 14th of last year. From then through Sunday, Granderson has 22 HR and 51 RBI in 71 games. On a 162-game basis that's 51 HR and 117 RBI. He has a .938 OPS over that span.
Brian Heyman of the LoHud Yankees blog reports that since last Aug 14., only Jose Bautista and Troy Tulowitski have more homers than Granderson. Heyman also references the change in Granderson's swing instituted around that time by hitting coach Kevin Long.
So is Granderson a changed guy or is this just a got streak? I tend to doubt that he's a whole new guy. From September 25, 2008 to June 19, 2009 (also a period of 71 games) Granderson had 19 HR, 46 RBI, and an .846 OPS. Yes, those numbers aren't quite as good as he's done lately, but they're not that far off. If a few fly balls go over the fence or stay in the yard, the numbers would be just about identical.
It may be true, however, that Granderson's tweaked swing is helping him drive the ball just a little bit further, pushing his power numbers up a bit.
