DENVER -- Right-hander Carlos Torres, who pitched for the White Sox in 2009 and '10, spent last season in Japan and has made five starts at Triple-A Colorado Springs, will join the Rockies on Friday for the weekend series with the Braves at Coors Field.
The decision will be announced officially before Friday night's game.
Torres, 29, who takes the roster spot of starter Jhoulys Chacin, who was sent down to Colorado Springs on Wednesday, will be "right now a longer guy out of the bullpen," Rockies general manager Dan O'Dowd said Thursday.
By not calling up a starter, the Rockies are set up to skip Chacin's spot on Monday at San Diego and go with left-hander Drew Pomeranz on normal rest, and pencil in right-hander Jeremy Guthrie to return from his right shoulder injury on Tuesday, the day he is eligible to return.
Torres was was 1-3 with a 6.86 ERA in 13 games including six starts with the White Sox in '09 and '10. Last season, Torres went 1-2 with a 6.26 ERA in six starts for the Yomiuri Giants in Japan.
This season, Torres is 2-1 with a 2.88 ERA in five starts for the Sky Sox. He has 25 strikeouts against 11 walks, with five of those walks coming in his first outing of the season.
The Sky Sox replaced Torres with right-hander Brandon Hynick, a one-time prospect who threw a perfect game for the Sky Sox in 2009. Hynick was traded to the White Sox in late '09 for right-hander Jose Contreras. Hynick rejoined the Rockies' organization after being released by the Reds this spring, and has been pitching at the Rockies' extended spring training.
In another move, left-handed-hitting outfield prospect Charlie Blackmon was placed on the Colorado Springs seven-day disabled list with turf toe in his right big toe. It was the same injury that short-circuited his chances of making the Rockies during Spring Training.
Blackmon is hitting .203 with one home run and five RBIs in 17 games since being activated.
