A master of control, as a rookie reliever for the 1954 American League champion Indians, Mossi was 6-1 with a 1.94 ERA and was unscored upon in three World Series appearances against the Giants. From 1954 to 1958 (except for 1957, when he was a starter) Mossi and righthander Ray Narleski formed one of baseball’s best bullpen pairs. In November 1958, Cleveland sent them both to Detroit to acquire Billy Martin and Al Cicotte. Moved into the Tigers’ rotation, Mossi was 17-9 with 15 complete games in 1959. On a team that won 101 games in 1961, he led Tiger starters with a 2.96 ERA while going 15-7. After relief stints with the White Sox in 1964 and the A’s in 1965, he retired with what was then the best-ever fielding average for a pitcher.
