Philadelphia Phillies first baseman Jim Thome will have season-ending surgery on his right elbow next week. The four-time All-Star was placed on the 15-day disabled list July 1, his second stint on the DL this season. He hit .207 with seven homers and 30 RBI in 59 games this year. Thome played for Class-A Clearwater on Tuesday as part of his minor-league rehabilitation assignment. He went 4-for-9 with a home run in four games as the designated hitter for Clearwater, but the Phillies announced Wednesday that the slugger will miss the rest of the season. Dr. James Andrews will perform the operation in Birmingham, Ala., next Tuesday to repair a frayed tendon. Thome, who turns 35 on Aug. 17, has 430 homers since making his major-league debut in 1991. He is due about $12.5 million in 2006 and $14 million in each of the final two seasons of his six-year contract. The Phillies have a club option for 2009, and he has a no-trade clause.
