Wedge has spent the last two days in a hospital after being diagnosed with a very mild stroke suffered during batting practice Monday at Safeco Field, team officials revealed.
The 45-year-old skipper was helped off the field after feeling dizzy and has been absent since the incident.
Bench coach Robby Thompson has been in charge of the squad during the last three games, in which the Mariners were 1-2 against Cleveland.
The Mariners said Wedge is expected to make a full recovery, but won't be on the bench during the M's next series against Minnesota nor will he accompany the team when it goes on a road trip to Boston and Baltimore.
