Ed Hillel said:28 outs in a row to start a game is still pretty good, though.
Harvey Haddix did better than that. Pitching for the Pirates on May 26, 1959, he retired the first 36 Braves before Mantilla reached on an E5 leading off the bottom of the 13th, sacrificed to 2nd, IBB, double by Joe Adcock and he lost 0-1.
