Speier (shoulder) began a rehab assignment with High-A Everett on Wednesday, allowing three runs on three hits, including two home runs, over one inning. He struck out two.
It's not the result Speier was looking for in his first game action in three weeks, but he did notch a couple strikeouts. The Mariners have not revealed a target date for Speier's activation from the 15-day injured list, but as long as he bounces back well, he could join Seattle for the start of its road trip Friday.
