"That'd be the earliest," Wedge said. "We have to see how he feels tonight, see how he feels tomorrow."
Wedge said the best-case scenario would be for Saunders, who was the designated hitter on Friday, to DH again on Saturday and play the field Sunday before joining the Mariners at Safeco Field on Monday to play the Baltimore Orioles.
Saunders can't get back soon enough, Wedge said.
"His attitude has always been that way," Wedge said. "From the day we told him he was going to go on the DL. ... He's anxious to get back. He came in last night before he left. He's anxious to play, period."
Saunders was batting .286 with a home run, a double, a triple, five RBIs and three stolen bases before going on the DL.
"He took huge strides last year, and even coming into this year, he just kept going," Wedge said. "Both on and off the field for me. There's a lot of strength and personality there. There's leadership qualities there. There's a lot to like with Michael Saunders."
