SEATTLE — The Seattle Mariners placed rookie right-hander Bryan Woo on the 15-day injured list Tuesday with inflammation in his right forearm.
Seattle is expected to fill Woo’s spot in the starting rotation by promoting top pitching prospect Emerson Hancock from Double-A Arkansas. Hancock was in the clubhouse before Tuesday’s game against San Diego, but Seattle was expected to wait on the roster move until Wednesday.
Woo pitched six innings Thursday against the Los Angeles Angels, allowing two runs and four hits. The 23-year-old didn’t feel “100 percent” following a bullpen session, Mariners manager Scott Servais said.
“I thought he threw the ball outstanding the other night in Anaheim,” Servais said. “And I don’t think this is anything serious. It just didn’t feel 100 percent, so we’re giving him a chance to catch his breath.”
