The Rockies purchased the contract of left-handed pitcher Mark Redman from Triple-A Colorado Springs on Friday and designated catcher Alvin Colina for assignment.
The Rockies are the fourth organization for Redman this season.
He was a member of the Atlanta Braves’ season-opening rotation, but was released May 25. He was 0-4 with an 11.63 ERA while with the Braves.
Redman signed minor-league contracts with Texas and Toronto, but was released each time. He signed a minor-league deal with Colorado on Aug. 19. Redman was 0-0 with a 2.92 ERA in 12-1/3 innings for the Sky Sox.
The 33-year-old Redman was a first-round draft pick by the Minnesota Twins in 1995 and has a 64-80 record in 204 major league games with Minnesota, Detroit, Florida, Oakland, Pittsburgh, Kansas City and Atlanta.
Redman was an American League all-star last season with the Royals.
Colina, 25, did not appear in any games for Colorado this season. However, he did make a one-day appearance on the 25-man roster against Milwaukee on Aug. 8. Colina spent the season at Colorado Springs, where he was hitting .195 with five home runs in 80 games.
