With a fastball timed at 99.5 mph in 1965, Maloney won in double figures for the Reds each year from 1963 to 1969. He went 23-7 in 1963, and was 20-9 in 1965 while pitching two of his three no-hitters. His first, on June 14 against the Mets, lasted ten innings; he struck out 18, but Johnny Lewis hit a leadoff homer in the 11th (and Roy McMillan singled later in the inning), and Maloney lost 1-0. On August 19, he again pitched ten no-hit innings, this time completing a hitless, 1-0 victory over the Cubs. His third no-hitter was an easy 10-0 victory against the Astros on April 30, 1969. Maloney also threw five one-hitters. The strikeout pitcher fanned eight Braves in a row on May 21, 1963, tying what was then a modern NL record. That year, he struck out a career-high 265 in 250 innings. A damaged Achilles tendon and a shoulder injury shortened his career.
