Porcello did not resemble a pitcher with 17 losses. Instead, he looked more like the guy who won the 2016 AL Cy Young Award, which was apparent from the beginning when he needed just eight pitches to dispose of the Rays in the first.
Porcello allowed one unearned run on five hits to notch a quality start along with his 10th win.
The Red Sox added two more in the sixth on an RBI single by Betts and an RBI double by Rafael Devers for a 3-0 cushion.
The Rays scored in the eighth when Kevin Kiermaier grounded to first with one out. Mitch Moreland stepped on the base and tried to retire Mallex Smith at second to complete the double play. Instead, his throw hit Smith and went into center field, allowing Adeiny Hechavarria, who had hit a leadoff double and advanced on a passed ball, to score on the error.
