ARLINGTON, Texas (AP) - A.J. Pierzynski and Mike Napoli had run-producing hits in the first inning against their former team and the Boston Red Sox got above .500 for the first time since three games into the season with a series-clinching 5-2 victory at Texas on Sunday.
Napoli put the Red Sox ahead to stay with an RBI double, two batters before Pierzynski's two-run single. Both went to Boston as free agents after being in Texas - Pierzynski was the Rangers primary catcher last season, and Napoli was there the previous two years.
John Lackey (5-2) struck out nine while allowing two runs over seven innings. The big right-hander threw 75 of 105 pitches for strikes without any walks.
Rangers lefty Robbie Ross (1-4) made it through 6 2-3 innings and a career-high 112 pitches, settling down after being down 4-0 after two innings.
Koji Uehara, who also went from Texas to Boston in 2013, worked a perfect ninth for his ninth save straight save.
The Red Sox (19-18) won the last two games in the series after being held to one hit by Yu Darvish Friday night. They have won six of their last eight games, and have a winning record for the first time since winning two of three in the season-opening series at Baltimore.
Shin-Soo Choo homered for the Rangers, who have lost 10 of 14 overall and dropped seven of their last nine home games.
Dustin Pedroia's two-out solo homer in the seventh chased Ross, and was the first Red Sox hit since Jonny Gomes' one-out single in the third.
Ross faced the minimum 13 batters between that, with only one runner reaching on an error being wiped out on a double play grounder.
It was the second homer for Pedroia, who led off the game with a double before Napoli drove him home.
Lackey, a Texas native, made his 20th road start against the Rangers, surpassing Seattle's Felix Hernandez for the most. Lackey is 14-15 overall with a 5.71 ERA in his career against Texas - those are his most losses and highest ERA against any AL team.
Choo's fourth homer was an opposite-field shot to left-center in the fourth to make it 4-1. Mitch Moreland had an RBI double in the seventh before Lackey struck out his final two batters with two runners on base.
