David Allan Righetti, nicknamed "Rags", is an American professional baseball coach and former player. A left-handed pitcher, Righetti played in Major League Baseball from 1979 through 1995 for the New York Yankees, San Francisco Giants, Oakland Athletics, Toronto Blue Jays, and Chicago White Sox. He served as the pitching coach for the Giants from 2000 through 2017.
Righetti began his career as a starting pitcher, but the Yankees converted him into a relief pitcher, using him as their closer, in 1984. He won the American League (AL) Rookie of the Year Award in 1981. As a starter, he threw a no-hitter on July 4, 1983. As a closer, he was twice named the AL Rolaids Relief Man of the Year and pitched in two MLB All-Star Games. He was the first player in history to both pitch a no-hitter and also lead the league in saves in his career. Dennis Eckersley later duplicated the feat, as did Derek Lowe.
