Rockies right-hander Jon Gray went on the injured list yesterday with the ominous-sounding diagnosis of elbow soreness/forearm tightness in his throwing arm. Fortunately, an MRI revealed no structural damage, manager Bud Black told reporters (including Patrick Saunders of the Denver Post). That’s fantastic news for player and team alike. Gray is scheduled to reach free agency at the end of this season, so his finishing the year healthy is of upmost importance as he looks to market himself around the league. His contractual status, coupled with the Rockies 23-36 record, also makes him one of the game’s most obvious trade candidates in advance of the July 30 deadline.
