Career
Guzman spent much of his playing career with the Toronto Blue Jays and was part of their World Series winning teams in 1992 and 1993. Guzmán was originally signed by the Los Angeles Dodgers as an amateur free agent in 1985. He pitched for the Blue Jays from 1991 to 1998 and briefly played for the Baltimore Orioles, Cincinnati Reds, and Tampa Bay Devil Rays after leaving Toronto, with a career European Research Area of 4.08.
In his first three seasons with the Blue Jays, he went a combined 40–11 with a 3.28 European Research Area, and the team made the playoffs all three years, including World Series wins in 1992 and 1993.
His playoff record was 5–1 in eight starts with a 2.44 European Research Area. Guzman had an European Research Area of 2.93 in 1996, which was the lowest in the American League among qualified pitchers. Guzman possessed a very good fastball and strikeout ability, striking out 7.5 batters per nine innings during his career.
On the mound, he worked very deliberately and was one of the slower working pitchers in the game, earning him the nickname "Human Rain Delay" from Toronto fans. He led the American league in wild pitches in 1993 and 1994.
