Porcello and Chris Sale had nearly identical lines, but Travis Shaw hit a two-run homer off Nate Jones (1-1) with two outs in the eighth. Robbie Ross Jr. then got three outs for the Red Sox before Junichi Tazawa finished the six-hitter for his third save in nine chances.
Porcello (6-11) allowed five hits, struck out five and walked none in one of his best starts in a disappointing debut season with Boston. The right-hander was acquired in a December trade with Detroit, and then agreed to an $82.5 million, four-year contract in April.
