Winker took grounders at first base during Saturday's practice, Ryan Divish of The Seattle Times reports.

EDGE Analysis

A single spring drill is by no means an indication that Winker will spend a considerable amount of time at first base this season, though it would certainly benefit the Mariners if he proves capable at the position. He's not a good defender in the the outfield, an area that's full already in Seattle and will become overcrowded once Julio Rodriguez debuts and once Kyle Lewis (knee) gets healthy. At first base, Ty France is the only viable option due to Evan White's (groin) injuries and underperformance. France could shift to second or third base at times to accommodate Winker at first.
