Dodgers beat World Series champion Giants 2-1

Clayton Kershaw struck out nine in seven dominant innings and Matt Kemp scored the go-ahead run on a throwing error by catcher Buster Posey in the sixth, sending the Los Angeles Dodgers to a 2-1 victory over the defending World Series champion San Francisco Giants in their season opener Thursday night.

Kershaw (1-0) allowed four hits and walked one in his first opening-day start. The 23-year-old left-hander struck out three of the four batters he faced in the first, giving him 500 strikeouts in his career.

Jonathan Broxton, back in the closer's role after losing it in the second half of last season, gave up a one-out homer to Pat Burrell in the ninth but hung on for the save after a scoreless eighth by Hong-Chih Kuo.

Former Yankees star Don Mattingly won his managerial debut for the Dodgers, making him the first rookie manager to beat the defending World Series champions on opening day since Lou Piniella debuted with the Yankees on April 8, 1986.

Frank McCourt watched from the owner's box as his legal tussle with ex-wife Jamie McCourt over ownership of the Dodgers continues into a second season.

Tim Lincecum (0-1) gave up an unearned run and five hits in seven innings for San Francisco. The two-time Cy Young Award winner struck out five and walked three in his third consecutive opening-day start.

The right-hander was in control throughout, but his defense let him down in the sixth.

Kemp walked with one out and James Loney followed with a grounder to shortstop Miguel Tejada, who threw the ball away trying for the force, allowing Kemp to take third. Lincecum hit former teammate Juan Uribe in the hip with his next pitch to load the bases.

Posey, the NL Rookie of the Year last season, blocked a pitch in the dirt and tried to pick off Kemp, who took too big of a lead. The throw got past Pablo Sandoval, allowing Kemp to score.

The Dodgers added a run in the eighth on Loney's RBI double off Santiago Casilla after Kemp walked and stole second.

The Giants had two other errors, in addition to Posey's passed ball in the second, and they could have had a fourth. Center fielder Andres Torres would have been charged with an error for overrunning Uribe's bloop single, but Uribe was thrown out trying to take the extra base in the second.

The game between the bitter rivals began in unseasonable 85-degree heat. Two planes towed banners over Dodger Stadium during batting practice featuring insults directed at each team. As if the Dodgers, who missed the postseason last year, and their fans needed a reminder, another banner read, "SF Giants 2010 Champs Beat LA."

Four of the Giants' five hits were singles, including a grounder behind first base by rookie Brandon Belt in his major league debut.
