Haddix will always be remembered for taking a perfect game into the 13th inning against the Milwaukee Braves on May 26, 1959. He retired 36 consecutive batters in 12 innings, essentially relying on two pitches: fastball and slider. However, Braves pitcher Lew Burdette was also pitching a shutout, which was seriously jeopardized on only three occasions: the 3rd inning, when a base-running blunder negated three consecutive singles; the 9th, when Pittsburgh finally advanced a runner as far as third base; and the 10th, when pinch hitterDick Stuart came within a few feet of ending Burdette's shutout bid with a two-run homer. A fielding error by third basemanDon Hoak ended the perfect game in the bottom of the 13th, with the leadoff batter for Milwaukee, Félix Mantilla, reaching first base. Mantilla then advanced to second on a sacrifice bunt by Eddie Mathews, which was followed by an intentional walk to Hank Aaron. Joe Adcock then hit an apparent home run, ending the no-hitter and the game. However, in the confusion, Aaron left the basepaths and was passed by Adcock for the second out and the Braves won 2-0. Eventually the hit was changed from a home run to a double by a ruling from National League president Warren Giles; ultimately, only Mantilla's run counted, resulting in a final score of 1-0, but the Pirates and Haddix still lost. Haddix's -inning, one-hit complete game, against the team that had just represented the NL in the previous two World Series, is considered by many to be the best pitching performance in MLB history. Mazeroski later said of Haddix's dominance in the game, "Usually you have one or two great or spectacular defensive plays in these no-hitters. Not that night. It was the easiest game I ever played in." After the game, Haddix received many letters of congratulations and support, as well as one from a Texas A&M fraternity which read, in its entirety on university stationery, "Dear Harvey, Tough shit." "It made me mad", recounted Haddix, "until I realized they were right. That's exactly what it was." In 1991, Major League Baseball changed the definition of a no-hitter to "a game in which a pitcher or pitchers complete a game of nine innings or more without allowing a hit;" the rule's formalization had the effect of proclaiming Adcock's drive singularly fatal to Haddix's no-hit bid, irrespective of the score or the game's ultimate outcome. Despite his having thrown more perfect innings than anyone in a single game, Haddix's game was taken off the list of perfect games. Haddix's response was "It's O.K. I know what I did." In May 1989, Milwaukee's Bob Buhl revealed that the Braves pitchers had been stealing signs from Pittsburgh catcher Smokey Burgess, who was exposing his hand signals due to a high crouch. From their bullpen, Braves pitchers repeatedly repositioned a towel to signal for a fastball or a breaking ball, the only two pitches Haddix used in the game. Despite this assistance, the usually solid Milwaukee offense managed just the one hit. All but one Milwaukee hitter, Aaron, took the signals.
Career
Over his 14-year career, Haddix had a 136-113 record with 1,575 strikeouts, a 3.63 ERA, 99 complete games, 21 shutouts, 21 saves, and 2,235 innings pitched in 453 games. He was in the spotlight in the 1960 World Series against the Yankees. After winning Game 5 as a starter, Haddix relieved late in Game 7 and was credited with the win when Bill Mazeroski hit his Series-ending famous walk-off home run. Haddix went 2-0 in the 1960 Series, with a 2.45 ERA. As a hitter, Haddix was better than average, posting a.212 batting average with 95 runs, 37 doubles, 9 triples, 4 home runs, 64 RBI, 4 stolen bases and 46 bases on balls. Defensively, he recorded a.957 fielding percentage which was the league average at his position. Haddix later followed his namesake Brecheen into the ranks of major league pitching coaches, working with the New York Mets, Cincinnati Reds, Boston Red Sox, Cleveland Indians, and Pirates.
