McCarthy delivered, throwing two-hit ball over 7 2/3 innings for his first major-league win as the White Sox beat the Texas Rangers 8-0 Tuesday night for a doubleheader split.
"Right when we needed it," White Sox manager Ozzie Guillen said. "This was a big game for the team. I don't know what it means to him, his first major-league win, but for the team, that's a big win, huge."
Jermaine Dye had two homers and six RBI for the White Sox, who snapped a three-game losing streak.
McCarthy (1-1) was called up from Triple-A Charlotte earlier in the day to make his sixth major league start. He held the Rangers hitless over the first 4 1/3 innings until Alfonso Soriano's double.
"After the first game, I felt like it was about time I came in and contributed my part, and did well," McCarthy said.
In the first game, rookie left-hander C.J. Wilson allowed one run and two hits in five innings of relief for his first major league win, Mark Teixeira drove in six runs and hit a pair of two-run homers off Garland, and the Rangers won 8-6.
McCarthy struck out two and walked one, allowing only two runners as far as second. Bobby Jenks pitched 1 1/3 innings to finish the White Sox's eighth shutout of the season.
Dye had the 10th multihomer game of his career and first of the season while matching his career high for RBI.
"We came out and swung the bats good in both games," Dye said. "We had some tough luck in the first game but we bounced back in the second game."
Chicago built a 3-0 lead after two innings against Edison Volquez (0-1) in his first major league start.
Carl Everett drove in the first run with a first-inning sacrifice fly and Dye made it 3-0 in the second with a two-run homer.
Scott Podsednik had three hits in the second game and Rowand went 5-for-8 with four RBI in the doubleheader.
Volquez allowed five runs and six hits in 4 2/3 innings.
"I was nervous in the first inning, but in the second inning I was just throwing," Volquez said. "I felt good that they gave me an opportunity to pitch. I feel a little bad because I wanted to win my first game in the big leagues."
Dye added his 25th homer, a three-run drive off Wasdin in the seventh, to make it 8-0.
Wilson (1-6) had been winless in 12 major league appearances and in six minor league decisions this season. He hadn't won since 2003, missing the entire 2004 season recovering from elbow ligament replacement surgery.
After the game, the Rangers optioned Wilson to Double-A Frisco to create a roster spot for Volquez, who was called up from the same club. Rangers manager Buck Showalter said Wilson would be back with the Rangers next week when rosters are expanded to 40.
Teixeira's 33rd and 34th homers gave him six multihomer games this season and 10 in his career.
Teixeira's two-run shot in the fourth off Garland (16-8) gave Texas the lead for good at 7-5.
Garland, who started the day second in the AL in wins, allowed eight runs -- five earned -- and seven hits in 4 1/3 innings. He had his shortest outing of the season and is 1-4 in his last seven starts.
Francisco Cordero got three outs for his 29th save in 36 chances.
Geoff Blum's two errors led to three unearned runs, giving the White Sox six errors in a two-game span.
Chicago went back in front 3-2 in the second on Blum's run-scoring single. Texas answered with a three-run second with the help of Blum's error, getting an RBI single from David Dellucci and a two-run double from Teixeira to make it 5-3.
But Benoit couldn't hold the lead in the third as the White Sox tied it at 5-all on Rowand's two-run single.
Rowand's run-scoring single pulled the White Sox within 7-6, but Texas added another unearned run off Garland with the help of Blum's second error.
Blum misplayed Soriano's grounder for a two-base error, and Soriano scored on Adrian Gonzalez's single for an 8-6 lead.
- Both dugouts received a warning from home plate umpire Gerry Davis in the second game after Texas' Erasmo Ramirez hit Dye in the thigh with a pitch in the ninth. Guillen was furious after the game. "I'm not going to say they hit him on purpose," Guillen said. "But (Ramirez) never hit anybody. When you see how big a game Dye had, I don't like the way it happened." Showalter said it was not intentional. "I know what it looks like, but we don't do that. Believe me, that's not the case," Showalter said. "I understand what (Davis) was trying to do."
- Dye had six RBI for the fourth time in his career, second this season.
- The White Sox won for the first time in five games at Ameriquest Field this season. They were outscored 33-14 in the first four games.
- Willie Harris, called up from Triple-A Charlotte on Tuesday, got the first-game start at second base instead of Tadahito Iguchi, who made three errors on Monday night.
- The doubleheader was necessary to make up a rainout on May 28.
- Wilson's last victory was on July 9, 2003, while a member of the Frisco RoughRiders.
- Texas was shut out for the seventh time this season.
