Right-hander Juan Nicasio, out since June 2 with a strained left knee, will not throw his simulated game on Thursday because of fluid on the knee. Nicasio threw a 40-pitch bullpen session on Tuesday and ran agility drills, then reported with the fluid on the knee Wednesday. This is the second such buildup; doctors drained the knee days after the injury was sustained. Nicasio was hoping to begin an injury rehab assignment soon. Now that's uncertain.
Veteran pinch-hitter Jason Giambi was not available during Tuesday night's 3-2 victory over the Cardinals because of a stiff back, and his availability on Wednesday was questionable as well.
Giambi's lack of availability explains manager Jim Tracy's decision on Tuesday not to pinch-hit for pitcher Jeff Francis in the bottom of the fifth with two out and nobody on, even though Francis was not going to pitch the sixth.
With two out in the seventh on Tuesday night, Tracy made a double-switch to bring in reliever Matt Belisle. The problem was that it cost him outfielder Tyler Colvin, who had accounted for all of the Rockies' runs with a three-run homer earlier in the game. Tracy said the move pained him, but he had to use Belisle in the next inning -- a number of relievers weren't available because of Josh Outman's tough two-inning outing the previous night -- and he wanted to do all he could to delay Belisle's spot coming up in the batting order.
