Rangers' David Murphy is congratulated by Josh Hamilton after scoring in the eighth.

ARLINGTON, Texas — Pinch-hitter David Murphy delivered a tiebreaking, two-run double in the eighth inning and the Texas Rangers rallied for a 9-5 victory over the Boston Red Sox on Friday after raising their American League championship flag.

Murphy's slicing liner off Daniel Bard (0-1) kicked up chalk when it landed on the left-field line. That sent Rangers newcomers Mike Napoli and Yorvit Torrealba home to break a 5-all tie. Murphy scored on a double by Elvis Andrus before another double by AL MVP Josh Hamilton.

Napoli, Ian Kinsler and Nelson Cruz all homered off Jon Lester for Texas, which played its season opener exactly five months after a Game 5 loss to San Francisco at home ended its first World Series.

Darren Oliver (1-0) got the victory after allowing a tying homer to David Ortiz in the eighth. Adrian Gonzalez had two hits and drove in three runs in his Boston debut. Carl Crawford went 0 for 4 with three strikeouts while leaving a runner in scoring position each at-bat.

WHITE SOX 15, INDIANS 10: At Cleveland, Carlos Quentin homered and drove in five runs, Adam Dunn homered and had four RBIs in his debut for Chicago and the go-for-broke White Sox built a huge lead and held off Cleveland's scrappy comeback in their season opener. The White Sox splurged during the offseason in an attempt to win the AL Central after finishing second to Minnesota in 2010, and the club's $125 million payroll looks like money well spent — so far.

ROYALS 2, ANGELS 1: At Kansas City, Mo., Kila Ka'aihue hit Michael Kohn's second pitch of the ninth inning for a game-ending home run, lifting Kansas City over Los Angeles. Kohn (0-1) relieved Jordan Walden to start the ninth and was ahead 0-1 in the count when Ka'aihue, who had struck out twice, slammed the ball 393 feet to right.

BLUE JAYS 13, TWINS 3: At Toronto, J.P. Arencibia homered twice and drove in five runs, Jose Bautista and Adam Lind also went deep and Toronto handed Minnesota its third straight season-opening loss. Arencibia, who also hit two homers in his major league debut last August, tripled home two runs in the fifth.

ORIOLES 4, RAYS 1: At St. Petersburg, Fla., Jeremy Guthrie allowed three hits in eight shutout innings while outpitching David Price, and Baltimore opened the season with a victory over Tampa Bay. Taking up where they left off during a nice two-month stretch to end last season under manager Buck Showalter, the Orioles ruined a festive evening in which the defending AL East champions hoisted their latest division title banner at Tropicana Field.

MARINERS 6, ATHLETICS 2: At Oakland, Calif., Felix Hernandez gave up a two-run homer in the first inning to Josh Willingham, then found his Cy Young form in a hurry, pitching a five-hitter for his 12th career complete game and the majors' first this year, as Seattle Mariners beat AL West rival Oakland.

Chone Figgins hit a go-ahead solo home run in the sixth inning, Ichiro Suzuki singled twice, drove in a run and stole a pair of bases.
