Red Sox 2, Rangers 1: Mike Aviles singled in the go-ahead run in the ninth inning as visiting Boston snapped a four-game slide and earned a rare victory at Texas.

Kelly Shoppach added an RBI double and Alfredo Aceves picked up his 21st save in 25 chances for the Red Sox, who improved to 5-12 in their last 17 games in Arlington.

Texas closer Joe Nathan (1-3) came into a tie game in the ninth and got two quick outs before walking Daniel Nava and Jarrod Saltalamacchia. Aviles worked the count to 3-2 and reached out for a slider, sending a soft line drive just over the leap of shortstop Elvis Andrus to score Nava and grab the lead.

Boston struck first, pushing a run across in the fourth inning against Rangers rookie starter Martin Perez. Cody Ross drew a leadoff walk and looked like he would be stranded until Shoppach came up with two outs and drove a 3-1 pitch the opposite way, where it glanced off right fielder Daniel Murphy’s glove for an RBI double.

Texas got that run back in the sixth, when Andrus doubled off Clay Buchholz, moved to third on a wild pitch and came across on Josh Hamilton’s groundout. It marked the league-leading 81st RBI for Hamilton.

Perez, who was recalled to fill in for the injured Colby Lewis, ended up allowing one run and five hits in six innings.

Buchholz lasted seven frames, surrendering one run and four hits while walking three and striking out one. Vicente Padilla (4-0) tossed a scoreless frame for the win.
