I always feel sorry for this fella. As the game was 0-0 after 9 innings it didn't count as a perfect game. 12 perfect innings in total and still not on the official list.
On May 26, 1959, Harvey Haddix of the Pittsburgh Pirates pitched what is often referred to as the greatest game in baseball history.[59] Haddix carried a perfect game through an unprecedented 12 innings against the Milwaukee Braves, only to have it ruined when an error by third baseman Don Hoak allowed Felix Mantilla, the leadoff batter in the bottom of the 13th inning, to reach base. A sacrifice by Eddie Mathews and an intentional walk to Hank Aaron followed; the next batter, Joe Adcock, hit a home run that became a double when he passed Aaron on the bases. Haddix and the Pirates had lost the game 1–0; despite their 12 hits in the game, they could not bring a run home. The 12 perfect innings—36 consecutive batters retired in a single game—remains a record.
