Mariners' Jarrett Grube: Likely headed back to Triple-A soon

Grube, who was called up Wednesday, could be sent back to Triple-A Tacoma this weekend, the Tacoma News Tribune reports.

The Mariners needed a fresh arm, and Grube was it. He was scheduled to start Wednesday at Tacoma. Grube, though, is not considered a candidate for the Seattle rotation, so the team likely will add a starting pitcher Friday, which will cost Grube his spot.
