Rays - 100 000 000 - 1 7 1 Red Sox - 000 220 00x - 4 8 1Rick Porcello (7-6-1-0-5, 94) pitched seven strong innings, Xander Bogaerts belted a two-run homer in the fourth, and Dustin Pedroia added a two-run single in the fifth.
Porcello gave up a home run to his second batter of the afternoon, but Bogaerts erased Tampa's early lead with none out in the fourth, after Pedroia had walked.
In the fifth, Sandy Leon singled. He went to third and Mookie Betts reached second on an error by center fielder Steven Souza. Pedroia then brought both runners home with a single. Bogaerts walked and it looked like Boston was poised for a big inning. But the next three hitters - David Ortiz, Jackie Bradley, and Aaron Hill - were retired by Matt Moore (6-7-4-3-4, 107).
Matt Barnes pitched a perfect eighth and Koji Uehara allowed only a leadoff single in the ninth.
