Headley, 29, led the National League in RBIs in 2012 with 115 and finished fifth in NL Most Valuable Player voting. Last season, he suffered a fractured tip of his let thumb in Spring Training, and played during the season with left knee and right shoulder injuries, and batted .250 with 13 home runs in 141 games. Headley underwent arthroscopic surgery to repair a medial meniscus tear in the knee at the end of the season. This is Headley's final season of arbitration eligibility.
Blanks, 27, signed for $988,000, according to ESPN, and has a year of arbitration left. Blanks hit .243 with eight home runs and 35 RBIs last season.
The signings come one day after the Padres reached one-year agreements with All-Star shortstop Everth Cabrera ($2.45 million), pitcher Ian Kennedy ($6.1 million) and pitcher Tyson Ross ($1.98 million). Previously, they reached one-year deals with outfielders Seth Smith ($4.5 million) and pitchers Tim Stauffer ($1.6 million) and Eric Stults (2.75 million).
Pitcher Andrew Cashner is the Padres' lone remaining arbitration-eligible player. Unsigned arbitration-eligible players and their clubs will trade salary proposals on Friday. If an agreement can't be reached, an independent arbitrator will hear cases and choose either the player's or club's proposed salary for the 2014 season. Hearings will take place between Feb. 1-21.
Yahoo! Sports reported that Cashner is seeking $2.4 million and the Padres are offering $2.275 million. The parties have the option of reaching a one-year deal or using the figures as the basis for a multiyear agreement.
