Rockies lefthander Christian Friedrich, who was recently promoted to high Class A Modesto, has not pitched since June 10. Rockies farm director Marc Gustafson said Friedrich has been sidelined with irritation in the back of his left triceps—something that occurred during a bullpen session after his last start.

"We’re going day-to-day and we’re probably being a little conservative, but obviously we need to be," Gustafson said. "We’ll give him the time he needs to make sure he’s pain-free and has a full bullpen session before he throws again."

On the season, Friedrich is 4-3, 2.34 with 86 strikeouts and 20 walks over 65 innings.
