DENVER | The Colorado Rockies have bolstered their starting rotation, acquiring right-hander Jason Marquis from the Cubs for reliever Luis Vizcaino.

The 30-year-old Marquis was 11-9 with a 4.53 ERA last season for the Cubs. The Rockies also receive cash as part of the deal.

Vizcaino struggled in his first year with Colorado, going 1-2 with a 5.28 ERA in 43 relief appearances.

It's the second trade the Rockies have made this offseason. They dealt All-Star outfielder Matt Holliday to Oakland in November for reliever Huston Street, lefty Greg Smith and promising outfielder Carlos Gonzalez.
