Fatigued Chatwood leaves Arizona Fall League
By Thomas Harding / MLB.com
DENVER -- Rockies right-hander Tyler Chatwood has left the Arizona Fall League after four appearances because of fatigue, but there is no injury concern, the Rockies announced Tuesday.
Chatwood went 1-1 with a 4.60 ERA in 15 2/3 innings over four AFL games for the Salt River Rafters in an attempt to build up his innings. Add that to his time in the Majors (5-6, 5.43 ERA in 19 games, 12 starts) and his combined work in the Minors at Triple-A Colorado Springs and Double-A Tulsa (1-3, 4.70 ERA in 13 games), Chatwood threw 141 2/3 innings in 2012.
Because Chatwood, who turns 23 on Dec. 16, was in the Rockies' bullpen for part of the season and spent some time battling a chest muscle injury in the Minors, the club sent him to the AFL to make up for lost opportunity.
As a rookie in 2011 with the Angels, Chatwood threw 142 innings in the Majors plus 16 in Triple-A.
The Rafters moved Rockies prospect Cory Riordan from the bullpen to the rotation, and the Rockies sent right-hander Mikel Marbry to the Rafters to work in the bullpen. Marbry, 28, went 4-2 with a 4.02 ERA in 49 relief appearances at Double-A Tulsa in 2012.
Riordan, 26, went a combined 6-5 with a 4.37 ERA in 33 games, including 10 starts, with Double-A Tulsa and Triple-A Colorado Springs.
