The Dodgers and Clayton Kershaw are making progress towards a seven-year contract extension, according to a pair of sources.

The contract is expected to be the largest for a pitcher in Major League history.

The two sides discussed a variety of proposals earlier in the negotiations -- including 10 years, $250 million and 12 years, $300 million, sources indicated.

Kershaw has a 5-4 record and 1.84 ERA on the season.
