DENVER -- Rockies left-hander Brett Anderson, who suffered a broken left index finger on April 12, and righty Tyler Chatwood, who suffered a right flexor tendon strain April 29, will face hitters for the first time since their injuries on Monday in a live bullpen session at Coors Field.
Both are quick workers and innings eaters that, the Rockies hope, will help the pitching staff by taking pressure off the bullpen.
Rockies head athletic trainer Keith Dugger said lefty Boone Logan, who began throwing bullpen sessions late last week, will need some form of rehab assignment before being activated.
Also, righty reliever Rafael Betancourt, coming back from Tommy John surgery last September, will face hitters for a second time in a live bullpen session on Tuesday. Betancourt, under a Minor League contract, has said he'd like to be pitching at Rookie-level Grand Junction by July 1 and work his way back to the Majors before the end of the season.
