• Weiss said it's unlikely that right-hander Jhoulys Chacin will make his next start on Tuesday for Triple-A Colorado Springs at Memphis. Chacin, who sustained a right shoulder strain at the start of Spring Training and has been gradually working his way back, is determined to be healthy after throwing 80 pitches in his last start.
Weiss said the Rockies haven't come to an official decision, and his thought could change based on what happens in the coming days, but he is leaning toward having Chacin's next start be in the Minors.
• Weiss' effort to keep the right-handed-hitting outfielders sharp resulted in his starting Brandon Barnes, who had a key pinch-hit double Friday, and Drew Stubbs on Saturday, with Charlie Blackmon and Corey Dickerson sitting against Dodgers lefty Paul Maholm.
Blackmon, however, is hitting .398 and has done well against lefty pitching. That means he is a candidate to start the next two games, Sunday against the Dodgers' Hyun-Jin Ryu and Monday at Arizona against Wade Miley.
