The club's official tweet was that an MRI exam revealed Gonzalez had a strained right wrist, but there was no word on whether he will be placed on the 15-day disabled list.
Rockies head athletic trainer Keith Dugger said the club will have a better idea how much action Gonzalez will miss when he is re-evaluated on Friday before the Rockies open a three-game set against the D-backs in Phoenix.
Gonzalez, who first reinjured his wrist crashing into the center-field wall while making a catch on July 3, grimaced and doubled over in pain after fouling off a pitch from the Braves' Tommy Hanson in the bottom of the fifth inning. Ryan Spilborghs replaced him.Gonzalez's injury dates back to August, when he hurt his wrist and thumb while fouling off a pitch from the Giants' Jonathan Sanchez. Gonzalez went on to win the National League batting title, but his power was compromised for the rest of the season. This new wrist injury occurred just as it appeared he was recovering from the pain that forced him out of the starting lineup for all but one of nine games after the injury. Gonzalez returned to the regular lineup on Sunday. In the first inning on Thursday, he homered into the right-field bullpen off Hanson for his second home run of the homestand. Gonzalez's two-run homer on Tuesday night was part of a 12-3 victory over the Braves. He also knocked the walk-off single in Wednesday night's 3-2 victory over the Braves. The Rockies will begin a nine-game, NL West road trip on Friday that could go a long way toward determining if their playoff hopes are legitimate or a pipe dream. Colorado is 10 games behind the first-place Giants.
