• Weiss said he is not concerned long term about first baseman Justin Morneau's stiff neck, which has kept him out of action since Friday. However, Morneau will not play in either of the Rockies' split-squad games Wednesday, against the Cubs at Mesa or against the Rangers at Surprise.
"March 4 or whatever it is, you've got a lot of time," Weiss said. "My feeling is hitters don't need many at-bats down here, especially guys that have been around for a while."
• The Rockies are careful not to put a timetable on right-hander Jhoulys Chacin (shoulder strain and inflammation) and are prepared for him to miss some starts early in the regular season. But Weiss said he is progressing positively. The hope is Chacin can return to long-toss in a couple of days and eventually work up to bullpen sessions.
"Sometimes with injuries you hit a plateau and stay there for a week or two, but it sounds like he's progressing nicely," Weiss said.
