Barton leads A's past Rangers 7-6 in 13 innings

ARLINGTON, Texas (AP) - Daric Barton hit a two-out RBI single in the 13th inning after homering in the 11th, and the Oakland Athletics beat the Texas Rangers 7-6 on Tuesday night in the opener of a 3-game series between the AL West's top teams.

Barton had been 0 for 5 before his two-out solo homer. But the Rangers tied it in the bottom half of the 11th when David Murphy hit a leadoff single and scored on Julio Borbon's base hit.

Tyson Ross (1-0) pitched the final three innings for Oakland.

Mavs C Dampier has arthroscopic left knee surgery

DALLAS (AP) - Mavericks center Erick Dampier has undergone arthroscopic surgery to clean out debris in his left knee.

The procedure was performed Tuesday by Dr. T.O. Souryal.

Various ailments, including the balky knee, limited Dampier to 55 games this season. That was his fewest since he played 43 games for Golden State in 2000-01.

Dampier averaged 6.0 points and 7.3 rebounds in the sixth year of a 7-year, $73 million contract with Dallas.

Stars, G Lehtonen agree on 3-year, $10.65M deal

DALLAS (AP) - The Dallas Stars and goaltender Kari Lehtonen have agreed to a 3-year, $10.65 million contract extension.

The deal announced Tuesday locks up Marty Turco's replacement through the 2012-13 season. General manager Joe Nieuwendyk (NOO'-ehn-dyk) said last month the Stars were moving on without Turco, their top goalie for nine seasons.

Dallas acquired the 26-year-old Lehtonen in February from Atlanta. He was the No. 2 pick in the 2002 draft by the Thrashers.

Lehtonen was 6-4 with a 2.81 goals-against average in 12 games with the Stars this season.
