Gibson (2-5) allowed four runs on seven hits and three walks while striking out six over five innings, but received no decision Friday at the Rangers.
Gibson left the contest with a 5-4 lead, but the bullpen quickly lost the lead in the sixth inning, leading to the no decision. He's only fired one quality start over his last four outings, and he has a 5.02 ERA on the year. He'll make his next start after the All-Star break.
