Polanco is not in the Mariners' starting lineup against the Rangers on Saturday.
Polanco will take a seat after going 1-for-4 with two walks and two RBI during Friday's 7-6 extra-innings win. Julio Rodriguez will serve as the Mariners' designated hitter while Randy Arozarena, Luke Raley and Dominic Canzone start in the outfield from left to right.
