Gordon greeted reliever Stolmy Pimentel (0-1) by pulling a ball into the seats down the right-field line.
Eric Hosmer and Mike Moustakas also homered for the AL Central leaders, who had gone ahead on an RBI groundout by Lorenzo Cain in the ninth. Adrian Beltre's two-out RBI single in the bottom half tied the game again.
After Greg Holland (1-0) took over in the ninth and blew his first save in seven chances this year, the right-hander returned to throw a perfect 10th. It was his first outing this season that lasted more than one inning.
