Montes (hip) will serve as the designated hitter and bat eighth Tuesday against the Rangers.
Montes entered Seattle's last two games off the bench after suffering a hip injury Friday, and he's now feeling well enough to return to the starting nine for Tuesday's series opener. The 21-year-old homered in his MLB debut last Tuesday but has since gone just 1-for-10 with an RBI and six strikeouts in four contests.
