DENVER -- Rockies left-hander Drew Pomeranz is not certain to start Wednesday afternoon against the Brewers because of a soreness in his chest area on the left side, manager Jim Tracy said. Tracy said he and pitching coaches Bo McLaughlin and Jim Wright will discuss the issue, and monitor how Pomeranz (1-7, 5.04 ERA) feels. With days off working in his favor, Pomeranz has not thrown on three days' rest as often as other Rockies pitchers, but he is still battling periodic soreness. The Rockies entered the season looking to closely monitor the innings thrown by Pomeranz, who threw 119 1/3 between the Minors and Majors last season and has 111 1/3 this year -- 60 2/3 with the Rockies.
In other health developments: Outfielder-first baseman Michael Cuddyer, currently on the disabled list with a right oblique strain, said Monday night he will play at Triple-A Colorado Springs on Tuesday and Wednesday on a rehab assignment. He hopes to rejoin the club Thursday to open a four-game series against the Marlins. Shortstop Josh Rutledge limped after hitting a ground ball during Sunday's loss to the Giants and received postgame treatment for soreness in his left quadriceps. Manager Jim Tracy kept him out of the lineup on Monday but doesn't expect the problem to be serious. He also rested third baseman Jordan Pacheco. A CT scan has revealed that left-hander Christian Friedrich has a fracture of the L-5 vertebrae. The result confirms that he will miss the rest of this season. Friedrich is doing activities with the club but is wearing a solid back brace.
