Juan Dominguez may or may not make one more start in the minors. He’s not expected to rejoin the Rangers after rosters expand.
Dominguez will be sent to the instructional league on Sept. 15, as the Rangers want him to improve his slider and work on holding baserunners. The hope is for Dominguez to pitch in winter ball with the slider to go with his fastball-changeup combination. Exactly who will replace Dominguez in the Texas rotation remains unclear. With Monday’s day off, the Rangers won’t need a fifth starter until Saturday.
