Gibson (4-3) took the loss Tuesday in Texas, allowing three runs on seven hits while striking out four in 6.1 innings.
Gibson faced the minimum through the first four innings thanks to two double-play groundballs. In the fifth, he gave up back-to-back homers to Nathaniel Lowe and Jonah Heim. One inning later he gave up another run. It marked the second straight start and fourth time in his last nine in which Gibson didn't hand out a single free pass.
