Boston, MA (Sports Network) - Adrian Beltre finished 2-for-5 with a two-run homer and knocked in three runs, and Kevin Jepsen pegged pinch-hitter Daniel Nava with the bases loaded in the seventh inning to force in the go-ahead tally, as Boston downed the Los Angeles Angels of Anaheim, 7-5, in the middle test of a three-game set at Fenway Park.
Victor Martinez added three hits, an RBI and scored twice, while Bill Hall also homered for the Red Sox, who recorded their ninth straight win over the Halos this season and have taken 11 of the last 12 meetings.
John Lackey (11-7) beat his old club for the third time in 2010, allowing 10 hits and five runs with five strikeouts over seven innings.
Jonathan Papelbon turned in a scoreless ninth to post his 30th save and became the first pitcher in baseball history to record at least 30 saves in each of his first five full seasons.
Jepsen (2-3) took the loss and the blown save as David Ortiz scored the go- ahead run in the seventh inning. Jepsen was charged with two runs on two hits with two walks over one inning.
Boston forged ahead with a two-run seventh inning against Jepsen. Martinez singled and David Ortiz followed with a double to left-center, then two batters later Mike Lowell walked to load the bases. Jepsen then bounced a pitch in front of the plate that escaped to the backstop with pinch-hitter J.D. Drew at bat, which brought in Martinez with the tying run.
Drew was given a free pass before Nava was plunked to plate Ortiz for a 6-5 Red Sox edge.
In the home half, Marco Scutaro doubled and later scored on a Martinez base hit for a two-run lead.
Papelbon then closed out the game by fanning all three Angels he faced.
The Sox picked up a run in the first as Dustin Pedroia walked with one out, stole second, moved to third on a throwing error and later came in on a Beltre base hit.
Napoli reached the Green Monster seats to start the third, and Howie Kendrick added an RBI single in the fourth, but Hall led off the home fourth with a long homer to left.
However, Beltre ripped a two-run shot just to the left of dead center to make it 5-4 in the home half.
