The Padres and third baseman Chase Headley were over $3 million apart Friday when they exchanged arbitration salary numbers.

Headley is seeking $10.3 million for 2013. The Padres offered Headley $7.075. Headley made $3.475 million in 2012.

The Padres reached salary agreements with right-handed starting pitcher Edinson Volquez and catcher John Baker Friday. But they couldn't come to agreements with their last three arbitration eligible players – Headley, left-handed starting pitcher Clayton Richard and right-handed setup reliever Luke Gregerson.

The Padres reached agreements with five of their eight arbitration-eligible players. They earlier signed outfielder Will Venable, shortstop Everth Cabrera and left-handed reliever Joe Thatcher.

Volquez, 29, accepted $5.725 million for 2013, his final season of arbitration. He will become a free agent at the end of the 2013 season. Baker, who turns 32 Sunday, agreed to $930,000 for 2013. Volquez more than doubled his 2012 contract of $2,237,500. Baker made $750,000 for 2012.

Headley, 28, finished fifth in the National League Most Valuable Player voting after hitting .286 in 2012 with 31 homers and a league-leading 115 RBI. He was the league's Player of the Month for both August and September and won both the Gold Glove and Silver Slugger awards for National League third basemen.

Headley capped his breakout season by hitting .308 with 23 homers and 73 after the All-Star break.
