Logan, Chacin take steps in rehab process

MIAMI -- Two key Rockies pitchers beginning the season on the disabled list -- lefty reliever Boone Logan and righty starter Jhoulys Chacin -- made progress on Monday.

Rockies head athletic trainer Keith Dugger said Logan, signed for three years and $16.5 million even though he underwent a left elbow cleanup surgery while with the Yankees at the end of last season, threw 21 pitches in one inning on Monday. The plan is for him to make rehab appearances for Triple-A Colorado Springs on Thursday and Friday. Logan is eligible to be activated from the DL on Saturday, since his placement was backdated to the day after his only Major League Spring Training appearance.

Chacin is expected to be out until anywhere from late April to mid-May because of a right shoulder strain, but the rehab continued to go well Monday when he completed a 25-pitch bullpen session. He'll throw another 25-pitch session on Thursday, possibly with hitters standing in the box, Dugger said. After that, it's possible the hurler will face hitters swinging the bat.
