BOSTON -- It took nearly eight years, but Texas reliever Bryan Corey finally got his first win in the major leagues.
Ian Kinsler had a tiebreaking two-run single in the seventh inning and Corey outshined a pair of rookie left-handers for his first major league win, lifting the Rangers to a 7-4 victory over the Boston Red Sox on Saturday.
The teams were supposed to play a day-night doubleheader, but rain delayed the start of the first game 4 hours, 47 minutes, forcing the postponement of the nightcap, with the "day" game ending just over eight hours past its original scheduled 1:25 p.m. starting time.
The postponed game will be made up as part of a split doubleheader Sunday, beginning at noon. The regularly scheduled 2:05 game was moved to 5 p.m.
Corey (1-0), who began his major-league career with Arizona in 1998 -- and made just four total appearances with the Diamondbacks and Los Angeles -- struck out all four batters he faced for the win.
The 32-year-old Corey, whose last big league appearance came with the Dodgers in 2002, previously had one strikeout in just five innings.
"Honestly, I'm trying to learn from all my past experiences," said Corey, who also spent part of the 2004 season in Japan. "It's really good with all I've been through. To have it happen here, with all the baseball history."
Corey got his first big-league win on a day that was supposed to belong to Boston left-hander Jon Lester.
Corey had the game ball in his pocket as he spoke to the media.
"I'm very happy for Bryan," Rangers manager Buck Showalter said. "It's been a long road for him."
Highly touted Lester made his first start for the Red Sox and opened by striking out his first batter, Gary Matthews Jr. on four pitches before the Rangers scored a pair of runs. Mark DeRosa hit a two-run double down the left-field line following a double by Michael Young and walk by Blalock.
The 22-year-old Lester pitched 4 1/3 innings, giving up three runs and five hits with four walks. He struck out four before leaving to a standing ovation by the crowd.
"I thought he showed some of the things that we heard about him," Boston manager Terry Francona said. "Today was not an easy day to make a debut. He sat around and I'm sure he had a lot of anxiety."
Francona said Lester would make another start.
"I threw a lot of pitches in four innings. That's the biggest thing right now, to try to keep my pitching efficiency to a minimum," said Lester, who threw 102 pitches. "I was just happy to get the first one under my belt and get it done with."
Hank Blalock went 3-for-4 with a two-run homer and three runs scored for the Rangers.
Manny Ramirez hit his 450th career homer for the Red Sox, becoming the 31st major-league player to reach that plateau.
Francisco Cordero allowed one run in one inning and Akinori Otsuka pitched the ninth for his 11 save in 12 chances.
Blalock, and Mark DeRosa singled before Kevin Mench walked to load the bases with one out in the seventh against Boston reliever Julian Tavarez (1-1). Kinsler snapped a 4-for-25 drought with a grounder that rolled inside the third-base bag, making it 5-3.
Ramirez homered in the eighth off Cordero to bring the Red Sox within 5-4, but Blalock hit a two-run shot off reliever Keith Foulke in the ninth to make it 7-4.
Rangers rookie left-hander John Rheinecker, making his fourth major-league start, lasted 5 2/3 innings, allowing three runs and nine hits. He walked three and struck out one. He pitched eight or more innings in his previous two starts.
The Red Sox cut it to 2-1 in the first when Mark Loretta singled, moved to third on David Ortiz's single and scored on Ramirez's ground out. Boston tied it 2-2 in the third when Coco Crisp scored on Ortiz's double play grounder.
Texas regained the lead on Matthews Jr.'s sacrifice fly in the fourth, but Boston tied it on Alex Gonzalez's RBI single in the bottom half.
Ortiz came into the game just 4-for-24 in June. ... Jerry Hairston Jr., making his first start for Texas since being acquired from the Chicago Cubs on May 31, made diving catches of Mike Lowell's liners in the second and eighth. ...The Red Sox PA announcer informed the fans that it was "Free Dog Night" in the second inning. Management offered free hot dogs -- one per person per trip -- while supplies lasted. ... Lester was 3-4 with a 2.70 ERA in 11 starts with Triple-A Pawtucket.
