Moore's runner-up streak continued in the 1956 World Championship held at Judice's Academy in Brooklyn, New York. He clinched second place, to Willie Mosconi's now almost ubiquitous first, with a 150 to 50 score over Al Coslosky of Philadelphia in 15 innings, a win over Richard Riggie of Baltimore, 150 to 121, with an inspired run of 107 balls, but a loss to Lassiter, 150 to 70 in 7 innings. That same year Moore played Mosconi at a challenge match in Kinston, North Carolina. It was not Moore's day as Mosconi posted a career highlight; a perfect match—150 balls in a row in one inning.
