SEASON OVER: Chad Billingsley will undergo a season-ending operation next week to repair a partially torn flexor tendon in his right elbow. The operation could mark the end of Billingsley's time in Los Angeles, as the Dodgers are expected to decline the $14-million team option in the right-hander's contract for next season. Billingsley made the decision after a conversation Sunday with team physician Neal ElAttrache. "It's the best chance I'll be able to pitch next year," said Billingsley, who never returned from an operation he underwent last year to repair a torn ulnar collateral ligament. Billingsley said if he rehabilitates his flexor tendon instead of having it surgically repaired, there is significant chance he could reinjure his UCL. That would require him to undergo a second Tommy John operation. "The percentages weren't in my favor," he said. Billingsley said he expects to be sidelined for six months.
