Athletics signed RHP Phil Humber to a minor league contract. The 30-year-old right-hander spent the 2013 season with the Astros, compiling a horrendous 0-8 record, 7.90 ERA, 1.74 WHIP and 36/20 K/BB ratio over 54 2/3 innings. He's just two seasons removed from a very effective season in the White Sox rotation, so perhaps the A's feel like they can resurrect his career. He'll likely begin the 2014 season at Triple-A Sacramento.
