ARLINGTON, Texas -- Nick Tepesch allowed two home runs in the top of the seventh as the Chicago White Sox snapped a 2-2 tie and beat the Texas Rangers 5-2 on Wednesday night at Rangers Ballpark.

Rough seventh for Tepesch: For the second straight start, rookie Nick Tepesch had a rough seventh inning. He allowed two home runs with the game tied at two. White Sox third baseman Conor Gillaspie led off the inning with a 384-foot home run to right-center field. With two outs, leadoff hitter Alejandro De Aza smacked a two-run home run to right field for a 5-2 lead. Tepesch had allowed two home runs in 27⅓ innings before Wednesday's seventh inning.

Too long with Nick?: Rangers manager Ron Washington stuck with Tepesch after Gillaspie's tiebreaking home run even though the right-hander was around 100 pitches. The White Sox made the Rangers pay with De Aza's two-out homer for a three-run lead.

Eighth-inning threat crumbles: The Rangers hadn't scored against White Sox reliever Jesse Crain in 27⅓ innings before Wednesday night. They had one of their best shots at him after Elvis Andrus and Lance Berkman led off with singles. But Adrian Beltre continued his struggles with a fly out to center but did move Andrus to third. Nelson Cruz struck out on a high fastball. Sox left-handed reliever Matt Thornton came in and got David Murphy to ground out back to the pitcher.

Baserunning gaffe: The Rangers should have scored more in the bottom of the second. With the bases loaded, Ian Kinsler just missed a grand slam, as his line drive to left field hit off the top of the wall. The Rangers scored just one run because Geovany Soto didn't score from second base.

Beltre scuffles: Beltre, who had a two-run home run in his last at-bat Tuesday night, failed to get a hit with a runner at second base and two outs in the first inning. Beltre is four for his past 31 with runners in scoring position.

Frasor improving: Reliever Jason Frasor retired all four batters he faced with two strikeouts. Frasor hasn't allowed a run in his past six innings.

Up next: The Rangers and White Sox wrap up their three-game series Thursday night when rookie right-hander Justin Grimm (2-0, 1.59 ERA) takes on veteran right-hander Jake Peavy (3-1, 3.38 ERA) at 7:05 p.m. on Fox Sports Southwest and ESPN 103.3-FM and 1540-AM.
