Alex Liddi wasn't in the lineup Tuesday, as manager Eric Wedge went with a lefty-heavy batting order against Boston's Josh Beckett, but Wedge said he wants to play the rookie third baseman more and will have him in against some right-handers.
Wedge said Liddi could possibly be used at shortstop at some point, a position he played a few games in Triple-A Tacoma last year, and left field is also an option.
Catcher Miguel Olivo, on the 15-day disabled list with a sprained groin muscle, has been catching bullpen sessions in Tacoma, Wash., and will continue working out at Safeco Field now with the Rainiers heading out on the road.
Wedge said Olivo will be watched for a few days when the Mariners return to Seattle on Monday after their current road trip, and he then will be sent out on a Minor League rehab assignment.
Top-pitching prospect Taijuan Walker was removed from Double-A Jackson's game on Monday with a sprained right ankle in the third inning after getting his cleat caught on the mound running to cover first base.
Walker was feeling better on Tuesday and is considered day to day, with his next start scheduled for Saturday if he's deemed ready to go.
