BRADENTON, Fla. — Josh Beckett was happy with his outing — until the fifth inning.

Beckett failed to record an out in Pittsburgh’s six-run fifth as the Boston Red Sox lost 9-4 to the Pirates on Sunday.

“It’s a shame that a whole outing gets ruined by one inning, but that’s kind of the case,” Beckett said

Ronny Cedeno began the bottom of the fifth with a solo homer to left field. Dusty Brown walked, Andy Marte blooped a double and Jose Tabata was hit by a pitch.

Neil Walker lined the first pitch from reliever Scott Atchison into right for a tying single. Pedro Alvarez’s double put the Pirates up, 5-3. Lyle Overbay added a two-run single.

The first hit off Beckett was John Bowker’s solo home run in the second.
