Thanks to Maura Johnston for this :

Colorado Rockies shortstop Clint Barmes will undergo surgery tomorrow (Tuesday, June 7) to repair a fractured left clavicle. He is expected to miss a minimum of 12 weeks.

The surgery will be performed by Rockies Medical Director Dr. Thomas J. Noonan at the Steadman Hawkins Clinic in Denver. Dr. Noonan will re-set the fracture with the insertion of a plate.

Barmes suffered the injury at his home on Sunday evening (June 5) after taking a fall while carrying groceries up a flight of steps.

The 26-year-old was leading all National League rookies in nearly every offensive category this season, including batting average (329), runs (40), hits (74), doubles (16), home runs (8), RBI (34), total bases (116) and multi-hit games (22). He currently ranks seventh overall in the league in batting average, tied for third in multi-hit games, tied for fourth in hits, tied for fifth in runs scored, ranks sixth in total bases and tied for seventh in doubles.

Barmes will meet the media today at 3:00 p.m. in the interview room at Coors Field.

Ken Kercheval, Kellen Winslow Sr. and David Wells were unavailable for comment.
