ARLINGTON, Texas —

Marcus Semien hit a leadoff homer for the Rangers before Boyd struck out Corey Seager and Josh Jung. Boyd then had a 2-0 count on Adolis Garcia. He got checked on after throwing a pitch over the head of catcher Jake Rogers.

Vest replaced Boyd and struck out Garcia on three pitches to end the first inning. After giving up a leadoff double in the second and striking out two batters, Vest hopped awkwardly after his follow-through on a 1-1 pitch to Ezequiel Duran.

The trainer and Hinch again went out to the mound and Vest was visibly uncomfortable when he tried to stretch out and throw a warmup pitch.

Mason Englert took over for Vest and struck out Duran to end the inning. The Tigers went on to beat the Rangers 7-2.

Detroit currently has nine pitchers on the injured list.
