Athletics left fielder Mark Canha will hit second in Friday night's game against the Mariners, according to MLB.com.
A day before in the series-finale against the Rangers, Canha hit seventh. This season, Canha is already 4 of 9 with two double and four RBI. Catcher Stephen Vogt will move down the lineup and bat seventh.
Shortstop Marcus Semien and second baseman Eric Sogard also switched places from Thursday's lineup. Semien will hit eighth and Sogard ninth.
