Camp, who was the Cubs' only free agent, returns to the team after making a career-high 80 relief appearances. He finished tied for the Major League lead in appearances and ranked fifth in the National League with 77 2/3 innings. Camp, who turned 37 on Sunday, is the ninth Cubs pitcher to reach 80 appearances, and first since Sean Marshall did so in 2010.
Cubs manager Dale Sveum picked the durable right-hander as the team's first half Most Valuable Player. He totaled a career-high 18 holds, retired 57 of his first 80 batters faced and stranded 15 of 22 inherited runners.
Camp was released by the Mariners on March 23, and signed a Minor League contract with the Cubs three days later. He made the Opening Day roster and was one of the few veterans in the bullpen.
