to be St. Louis's pitching coach in 1959. Instead, the Cardinals hired him to scout and serve as a minor league coach. Not enjoying the arrangement, Maglie did not renew his contract for the 1960 season. The Boston Red Sox hired Maglie to be their pitching coach before the 1960 season, and he served in that capacity for the next three years. Under his tutelage, Bill Monbouquette had 17 strikeouts in a game in 1961 and quoted Maglie after the feat. "Sal talked about stuff like ‘move this guy off the plate, move his feet, move his legs,’ and oh, he did preach: ‘throw that ball inside!’ And he didn’t mean pitch to get a strike on the inside corner. He meant you’ve got to set that hitter up with a pitch way inside!" When Monbouquette and Earl Wilson threw no-hitters in 1962, they credited Maglie with their improvement. "He taught me how to use the lower part of my body," Dick Radatz said, crediting the advice with adding four or five miles an hour to his pitches' velocity. "I think he was a fine pitching coach. What he taught me helped me for the rest of my career. Without that, I don’t think I’d have been the pitcher I was." When Johnny Pesky replaced Pinky Higgins as Boston's manager after the 1962 season, Pesky chose not to bring back Maglie for 1963, preferring instead to pick new coaches. Maglie did not initially pursue another coaching job because his wife, Kay, was diagnosed with cancer in 1963. He invested in local businesses around Niagara Falls, engaged in public speaking, and joined the New York State Athletic Commission (NYSAC) in 1965. The NYSAC post forced him to turn down an offer to return to the Red Sox in 1965, but he signed a two-year contract to become their pitching coach again in 1966. He was the pitching coach for the "Impossible Dream" Red Sox that went all the way to the 1967 World Series before losing in seven games to the Cardinals. Jim Lonborg, the AL Cy Young Award winner that season, credited his effectiveness that year to Maglie's lessons on pitching inside. The Red Sox later fired Maglie after losing the 1967 World Series, and Maglie criticized manager Dick Williams in an interview a week later. "Dick Williams gave me the biggest disappointment I ever got in baseball," Maglie said.
