Short made his first appearance on the mound on April 19, 1959 against the Cincinnati Reds, appearing in the 2nd inning to replace Jim Owens. He allowed five runs on four hits while striking out three and walking three in 3.2 innings. Short was considered a top pitcher from 1964 through 1968 with the Phillies. He was 17–9 in 1964, with a 2.20 ERA in 220 innings pitched. It was his career-best ERA and was third in the league behind only Sandy Koufax and Don Drysdale. Teammate Jim Bunning was 5th that season with a 2.63 ERA. Juan Marichal finished 4th. That year, however, the Phillies and Short suffered a historic collapse in the pennant race. After leading by six and a half games with 12 to go, managerGene Mauch decided to start his two aces, Bunning and Short, for eight of the last 12 games. Short pitched respectably despite the heavy workload, giving up only six earned runs in 18 innings over his final three starts. But weak hitting, ineffective relief pitching and poor defense doomed Philadelphia. The Phillies lost three games in a row to the hot St. Louis Cardinals, who won the NL race by 1 game and defeated the New York Yankees in the 1964 World Series. On October 2, 1965, Short threw 15 shutout innings at Shea Stadium, striking out 18 Mets only to receive a no-decision. The game would end in a scoreless tie after 18 innings. Short ended up winning 55 games from 1964 through 1966, topping off with a 20–10 record in 1966. A back injury during the 1969 season would curtail his season while also proving to hurt his career. His final appearance on the mound was on September 18, 1973 against the Cleveland Indians. He entered in relief of Jim Colborn in the ninth inning, trying to preserve a 5-4 lead with a runner on second base. Facing John Ellis, Short allowed a home run as the Indians won the game 6-5. In 15 seasons, Short finished with a 135–132 record, just over a.500 winning percentage. He had a career ERA of 3.43 and 1629 career strikeouts in 501 games. He allowed 886 earned runs in 2325 innings pitched. Short ranks 4th among Phillies pitchers all time in wins, 5th in games appeared in, 3rd in games started, 19th in complete games, 4th in shutouts, 4th in innings pitched, and 4th in strikeouts.

Between 1985 and 1988, Short taught young pitchers at Suburban Baseball Camp, which was held at Barness Park in Warrington, Pennsylvania. He suffered from diabetes in his later years, along with trying to support his three sons. While working for a Wilmington insurance agency in October 1988, he suffered a ruptured brain aneurysm, lapsing into a coma. He died on August 1, 1991 in a convalescent home, having never regained consciousness. He was posthumously named to the Philadelphia Baseball Wall of Fame the following year. In 2016 Short was one of 16 new members inducted to the Philadelphia Sports Hall of Fame.
