On April 21, 2012 — Phillip Humber’s first major league complete game is baseball’s twenty-first perfect game when he retires all 27 Mariners he faces in the White Sox’ 4-0 victory at Safeco Field. The 29 year-old right-hander, who had Tommy John surgery in 2005, is the third Pale Hose pitcher to accomplish perfection, joining Mark Buehrle (2009 vs Tampa Bay) and Charles Robertson (1932 vs Detroit).
