Suter was placed on the disabled list Friday with forearm tightness.
The assignment was made retroactive to July 3, so there's at least a chance Suter is able to return before the All-Star break. Forearm tightness is sometimes the initial diagnoses that precedes a more serious injury, though the severity of this particular case is not yet clear. Aaron Wilkerson was recalled from Triple-A Colorado Springs and will start in Suter's place Saturday against the Braves.
