San Diego Padres v Seattle Mariners

The San Diego Padres are expected to offer third baseman Chase Headley a multi-year extension that would make him the highest-paid player in franchise history, according to the San Diego Union-Tribune.

Headley, who missed the first two weeks of the regular season with a thumb injury, has posted a  .280/.373/.540 line in 13 games this year, with three home runs. Over his career, the former second round pick of the Padres in the 2005 draft owns a .273/.352/.420 line with 70 home runs, and a 16.1 combined fWAR.

This season, Headley will earn $8.575 million and is arbitration eligible next season. He isn’t eligible for free agency until the 2015 season.

The largest deal in franchise history is still Jake Peavy’s four-year, $54 million deal, signed in 2007, with the next largest being a four-year, $34 million deal to Phil Nevin back in 2001.

UPDATE: According to Corey Brock of MLB.com, Chase Headley maintains he will not negotiate a new contract during the season.

“We made it abundantly clear [before] that we didn’t want to talk about it during the season I didn’t think that for me and for the team that it was good to get caught up with all of this during the season. … It’s flattering they feel the way they feel about me. I love playing in San Diego, I love the fans. But I just don’t think now is the time to get involved with this. That’s it. If there’s an opportunity to engage after the season, so be it. I didn’t want to have to deal with the fallout I’m dealing with”
