Agreeing to a deal that is reportedly being discussed would make the Dodgers ace the highest paid pitcher in baseball history.

Clayton Kershaw and the Dodgers are working on what could be a record contract extension for the ace left-handed pitcher, per Ken Gurnick of MLB.com.

Kershaw, who turns 26 in March, was one of 146 players to file for salary arbitration on Tuesday, and with his two Cy Young Awards in the last three seasons could set a record for salary through the process for a player with five years of service time. But rather than a one-year deal, the Dodgers are discussing a mega-deal that would keep Kershaw for some time from reaching free agency, which he is eligible to do after the 2014 season.

"The Dodgers and Kershaw have been in discussions over a record-breaking deal that could pay $30 million per season for as many as 10 years," wrote Gurnick.
