• The results of Nicasio's 5 2/3-inning start against the Brewers were mixed -- three hits, three walks, three strikeouts. But Weiss saw a split-finger pitch that could take him deep into ballgames when the games are for real.
"He's moving forward," Weiss said. "The thing I liked today was he threw some real good splits. That's the most confidence I've seen him have in that split-finger. I think that's the pitch that's really going to take him to the next level.
"If that's a pitch he can develop a lot of confidence in, it makes him a different guy."
• Rockies right-handed pitcher Jhoulys Chacin's comeback from a right shoulder strain took a step forward Thursday, when he threw off the mound. The next step for him will be a bullpen session. Rockies senior vice president of Major League operations Bill Geivett said Chacin won't be back until sometime in May, but Chacin said if rehab goes well there's a possibility he'll return in April.
