The recently acquired Resop, reeled in via trade from Pittsburgh on Nov. 30, is reportedly set to make $1.35 million in 2013.
The 30-year-old righty only further deepens an already talented A's relief corps that includes the likes of Grant Balfour, Ryan Cook and Sean Doolittle. Resop tossed a career-high 73 2/3 innings for the Pirates last season, compiling a 3.91 ERA along the way.
The A's still have four players on their roster eligible for arbitration: Jerry Blevins, George Kottaras, Brandon Moss and Seth Smith. Teams and players submit arbitration salary figures on Jan. 18.
