Sloppy defense contributes to loss: The Red Sox didn't help themselves at all in the field Friday night, committing three errors, two of which led to two unearned runs, and in turn, a loss to Houston. They were nearly out of trouble in the second inning when Steve Pearce threw wildly past Chris Sale, who was covering first. The ball ended up behind the plate where Sandy Leon retrieved it, then lost a foot race to home plate as second baseman Aledmys Diaz, who scored all the way from second. A two-out error by shortstop Xander Bogaerts didn't prove as costly in the third, but in the fourth, with runners at the corners and one out, Bogaerts tried to throw home to cut down Robinson Chirinos and threw wildly, past Leon. The Sox then had Jake Marisnick in a rundown between first and second, but as second baseman Michael Chavis ran Marisnick back to the first base bag, Pearce ran past the baserunner, giving him a clear path back to the bag.
