Bobby Korecky (1-0) tossed 1 2/3 perfect innings for Minnesota to earn his first major league win. He also recorded his first major league hit in the 11th.

"It's exciting to win like this," Korecky said. "We've had a lot of close games lately and lost a few, so to come back like this at home in the first game of the series hopefully can get us back rolling again and we'll see what we can do."

Minnesota starter Boof Bonser threw 6 1/3 innings, allowing four runs - three earned - on six hits without issuing a walk. He struck out five.

Milton Bradley was 2-for-6, scoring twice with an RBI and Hamilton was 2-for-6 with his 11th home run of the season for the Rangers, who dropped their second straight game after taking 13 of 17 overall.

Texas starter Scott Feldman surrendered five runs on seven hits and two walks through six innings.

Franklyn German (1-3) came on to work the 12th for Texas. Carlos Gomez led off with an infield single and advanced to second on a groundout. Clark then hit a ball over the outstretched glove of Hamilton to plate Gomez for the winning run.

Texas started the scoring with a two-out homer to left-center from Hamilton in the first.

Texas added another run in the third on a two-out homer from Ian Kinsler.

Minnesota got on the board in the bottom half. An error by Hamilton allowed Brendan Harris to advance to third on a two-out single and Mauer followed with a single to left.

Game Notes:

Texas has the best record in the major leagues since April 25th (15-7)...The Rangers have won seven consecutive series, matching the second longest streak in team history, yet the club is still two games under .500 (22-24)...Cuddyer started in center field for the Twins for the first time in his career, moving over from his normal right field position; Cuddyer has now played every position in the field for the team at least once except for pitcher and catcher...Jason Kubel got the start in right field...Texas started a 10-game road trip Monday night.
