The Colorado Rockies are working "multiple fronts as they attempt to bolster their rotation," and the club has expressed interest in several free agents, including right-hander Kevin Correia and left-hander Jeff Francis, reports Troy Renck of The Denver Post:

The Rockies are working on multiple fronts as they try to attempt to bolster their rotation. While a trade remains possible, Colorado has expressed interest in numerous free agents, including right-hander Kevin Correia and left-hander Jeff Francis, according to sources.

Renck adds that the Rockies are seeking a pitcher to fill the role of right-hander Jeremy Guthrie, who the team traded to the Kansas City Royals last summer. Colorado wants a pitcher that offers a reliable arm and gives the team a chance to win every five days.

Renck believes Correia fits the profile and adds that the 32-year-old has pitched well at Coors Field (3.61 ERA in 42-plus innings).

Over 32 appearances, including 28 starts, for the Pittsburgh Pirates last season Correia maintained an ERA of 4.21. He owns a career ERA of 4.54 over 10 seasons at the major league level.

Francis, 31, posted an ERA of 5.58 over 24 starts for the Rockies last season. He owns a career ERA of 4.86 over eight seasons.
