Jeff Samardzija struggled with his command at times in a three-inning outing Wednesday in a Colorado Rockies split-squad's 7-5 victory over the Chicago Cubs on Wednesday.

The Cubs' possible opening-day starter gave up two straight singles then, after a sacrifice bunt, hit a batter and walked the next in a rocky two-run third inning. In three innings, he gave up three runs and four hits.

Rockies projected starter Tyler Chatwood gave up one unearned run in 2 2-3 innings. He walked two and struck out three.

The Rockies committed three errors behind Chatwood, who gave up only one hit.

Javier Baez, rated the No. 5 prospect by Baseball America, and George Kottaras connected for back-to-back homers in the sixth off the Rockies' Chris Martin.
