LoHud's Josh Thomson is reporting that the results for Curtis Granderson's MRI are back and show that he has a Grade 2 strain of the left groin. He will be placed on the 15-day DL either and the Yanks will callup Mark Melancon from Scranton-Wilkes Barre. There is no timetable for his return at the moment.
You figure Brett Gardner will start in center everyday now, with Randy Winn and Marcus Thames splitting the left field duties. As of now I assume Thames will start against lefties and Winn will start against righties.
If there's a positive in all of this, it's that Mark Melancon will get another shot in the big leagues, and with the way the bullpen has looked lately they could use another arm. In 13 games for the Yankees last year, Melancon went 0-1, with a 3.86 ERA. In 16.1 innings he allowed 7 ER on 13 hits, walked 10, and struck out 10. This year for Scranton/Wilkes-Barre he's 3-0, with a 1.76 ERA in ten games. In 15.1 innings pitched, he's allowed 3 ER on 13 hits, walked 5, and struck out 15.
