Paul John Quantrill (born November 3, 1968) is a Canadian former professional baseball right-handed relief pitcher. He played in Major League Baseball (MLB) for 14 seasons, from 1992 to 2005; his longest tenure was six seasons with the Toronto Blue Jays. Quantrill appeared in 80 or more games five times, led his league in pitching appearances for four consecutive seasons, and did not walk more than 25 batters in a season from 1996 onwards.
Originally considered a starter, Quantrill eventually found consistency as a reliever after several years of splitting time between the bullpen and the starting rotation for several teams. Some of his best years came for the Toronto Blue Jays, a team located in his home province of Ontario. Quantrill earned a reputation for being very durable and having impeccable control; commentators[who?] often joked that he had a "rubber arm".
Before the 2004 season, Quantrill signed a two-year, $6.8-million deal with the New York Yankees. Quantrill pitched effectively for the Yankees as a set-up man for most of the season, leading Yankees announcer Michael Kay to create the nickname “Quan-Gor-Mo” for the “three-headed monster” that made up the Yankees usual bullpen progression of Quantrill, Tom Gordon and Mariano Rivera (known as “Mo”).[1]
