Philip Humber Joins Cy Young, Sandy Koufax, Other Legends on Exclusive Perfect Game List (Photos)A no-hitter is one of the toughest feats in all of sports. A perfect game is even harder to accomplish.

Chicago White Sox starter Philip Humber managed to toss a perfect game on Saturday, though. He threw 96 pitches and struck out nine batters in a 4-0 victory over the Seattle Mariners at Safeco Field.

Humber is the 21st pitcher in major league history to pitch a perfect game. He joins a prestigious list that includes the likes of Cy Young, Kenny Rogers and Roy Halladay.

Humber may not have the best "stuff," but he had enough to take down the weak offense of the Mariners on Saturday.
