From MLB.com:

The ever-widening gap between Alex Rodriguez and his American League contemporaries is quickly evolving into a chasm. After a torrid June that saw the New York third baseman bat .406 with 39 hits and a league-high .781 slugging percentage, Rodriguez garnered his second American League Player of the Month award in three months, his fifth as a Bronx Bomber and the ninth of his career.

As part of the award, he gets a 52" LCD TV from Sharp.

His injury last night is being called a "strained hamstring". We'll know more today as he's going in for tests.
