Shaun Marcum (thoracic outlet surgery) will throw another live batting practice session Tuesday.
Marcum has been brought along slowly this camp as he works his way back from thoracic outlet surgery. He won't have time to compete for the fifth starter job but should serve as nice rotation insurance at Triple-A.
David Lough (neck) will rest for the next 48 hours.
Lough has been out since last Friday due to a stiff neck. It shouldn't be a long-term concern.
Casper Wells was scratched from Monday's lineup due to back spasms.
It's not clear how long he might be sidelined. Wells is competing for a bench spot as a non-roster invitee.
Cubs prospect INF Arismendy Alcantara was 3-for-3 with his first spring home run on Sunday against the Mets.
Headed into the game, Alcantara, 22, was 0-for-12 in spring games, so his breakout performance on Sunday is certainly encouraging. Last season, the middle infielder batted .271/.352/.451 with 15 home runs and 31 stolen bases at Double-A Tennessee. Alcantara is likely to reach the major leagues at some point during the upcoming season, but keep in mind he has Javier Baez ahead of him on the organizational depth chart.
Nick Masset recently underwent surgery to have a staph infection removed from his right shoulder.
Staph infections can be scary, but Masset has returned to Rockies' camp and is back on schedule. The reliever thinks he still has time to get ready for Opening Day.
Mike Olt was scratched from Monday's lineup due to fatigue in right shoulder.
Olt has battled shoulder issues on and off all spring, but Cubs manager Rick Renteria isn't concerned. "We're looking to keep him healthy," the skipper said. Olt is expected to begin the season at Triple-A.
Cubs manager Rick Renteria said Monday that Starlin Castro (hamstring) continues to make progress and could make up for lost time with at-bats in minor league games.
Renteria has said previously that he was hoping Castro could return to Cactus League games this week. There doesn't appear to be much concern that the shortstop won't be ready for Opening Day as long as he can avoid setbacks.
Chase Headley (calf) is hoping to make his Cactus League debut on Thursday.
Headley faced live pitching over the weekend and felt fine. It's not clear how much, if any, running he's done, so he could be eased into game action in the designated hitter spot. The third baseman remains hopeful of getting ready in time for Opening Day.
