ARLINGTON, Texas -- Vicente Padilla kept throwing fastballs, one after another. Inside and outside. Up and down.
"Each one of those pitches looks different halfway to home plate. His ability to mix them all in, use every part of the strike zone was key," Texas catcher Rod Barajas said. "I had the easiest job on the field. He had it going on."
After allowing runners in each of the first four innings, twice hitting A.J. Pierzynski with pitches, Padilla (6-4) retired 14 of his last 16 batters. The right-hander struck out seven -- five in a six-batter span -- and walked three.
Pitching coach Mark Connor said the first 50 pitches Padilla threw, into the fourth, were fastballs.
"You want the other team to make the adjustment, and for some reason they weren't able to get on that fastball," Barajas said.
Francisco Cordero pitched the ninth to wrap up the Rangers' fifth shutout of the season. The White Sox were held scoreless for only the second time.
Hank Blalock snapped out of his offensive slump with a homer and an RBI double in his turn as the Texas designated hitter.
Blalock led off the second with his 10th homer -- a 416-foot blast into the second deck of seats in right field -- that put the Rangers ahead to stay. His double an inning later was part of a four-run outburst in which they batted around to go up 5-0.
Blalock was the DH for only the second time this season. The two-time All-Star third baseman was 2-for-17 his previous four games, 0-for-8 in the series, before his 21st multihit game.
Gary Matthews Jr. was 3-for-5 and also homered for Texas, which avoided its first three-game losing streak since being swept May 5-7 by the New York Yankees.
Javier Vazquez (7-4) struck out seven over six innings, but allowed six runs and 10 hits to end his three-game winning streak.
Mark DeRosa, who started at third instead of Blalock, made a run-saving defensive play in the third after the White Sox -- helped by a walk and a wild pitch -- had runners at second and third with no outs in a 1-0 game.
"It was an instinct play. I saw (Mackowiak) out of the corner of my eye and I knew that I could beat him to the plate," DeRosa said.
"If you don't make that play, the gates are open," manager Buck Showalter said. "Where they are in their order to come out with no runs ... it's a crazy game."
Blalock's third-inning double came right after Mark Teixeira's RBI double, which followed Michael Young grounding into a double play. Kevin Mench and Ian Kinsler had consecutive RBI singles later in the frame.
Pierzynski was hit by pitches his first two at-bats, prompting home plate umpire Phil Cuzzi to issue warnings to both benches in the fourth.
"I don't know what the deal was. He had pretty good control and then he runs two first pitches in on me," Pierzynski said. `Why did he do it? You're going to have to ask him. I faced him maybe two times in the National League."
Padilla didn't comment after the game.
Pierzynski took a called third strike, a pitch on the outside corner, when he batted in the sixth.
Sean Tracey relieved Vazquez to start the seventh, and the right-hander got leadoff hitter Blalock out on a grounder. But White Sox manager Ozzie Guillen slammed a water bottle to the ground, brought Agustin Montero into pitch and then was seen in the dugout barking at Tracey, who pulled the collar of his jersey over his head.
"I tried to get Montero ready (to face Blalock) and wasn't able to. It was a little late," Guillen explained. "It was my mistake. I didn't get him up quick enough. I didn't want Tracey in that situation."
Tracey refused comment.
