The Dodgers, focusing on more immediate pitching concerns, have yet to begin talks on a possible new long-term deal for star lefthander Clayton Kershaw, who finished second in the N.L. Cy Young voting this year after winning the award in 2011, sources said. Though Dodgers GM Ned Colletti has said Kershaw is on their winter agenda and it's hard to imagine baseball's new biggest spenders letting one of baseball's best starting pitchers get away, Kershaw has beefed up his representation, as he's moved with longtime point man J.D. Smart from Hendricks Sports to Excel Sports. Veteran New York-based agent Casey Close, who will assist Smart in talks, oversees Excel's baseball department.
