The Rockies activated catcher Ramon Hernandez from the disabled list. Hernandez had missed 42 games while recovering from a left hand injury.
The Rockies filled the roster vacancies by purchasing the contracts of infielder Josh Rutledge from Tulsa and right-hander Mike Ekstrom from Triple-A Colorado Springs.
To clear a spot on their 40-man roster for Ekstrom, the Rockies moved pitcher Jorge De La Rosa from the 15- to the 60-day disabled list. De La Rosa has been sidelined since undergoing reconstructive elbow surgery a year ago.
Rutledge, Ekstrom and Hernandez were all available to play against the Phillies.
Helton was batting .235 in 63 games, well below his career average of .320. He has been bothered recently by hip soreness and he's expected to undergo an MRI soon to try to determine the extent of the injury. It's the first trip to the disabled list for the 38-year-old Helton since a stint from July 7-Aug. 3, 2010, because of lower back stiffness.
Rutledge, one of the Rockies' top prospects, was hitting .306 with 13 home runs and 35 RBIs for Tulsa.
Prior to his recall, Ekstrom was with Colorado Springs, going 2-1 with a 2.64 ERA and one save. He was a non-roster invitee to the Rockies spring training after signing with the team last December as a minor league free agent.
Ekstrom has pitched in the big leagues with San Diego (2008-09) and Tampa Bay (2010-11). He's 0-3 with a 5.36 ERA in 36 career appearances.
