David Wells began his MLB career with the Blue Jays after being selected in the 2nd round of the 1982 draft. Wells went 30th overall while Barry Bonds went 39th overall in that draft class to the San Francisco Giants. Bonds would opt not to sign and attend Arizona State University.
Boomer would spend six seasons with the Jays before being released in the spring of 1993. He would latch on with the Detroit Tigers days later.
Wells would reunite with the Blue Jays after the team acquired him back in the Rogers Clemens deal with the Yankees in 1999. During his two stints in Toronto, Wells compiled a 15.0 WAR in 306 games that included 138 starts.
His best season statistically would come in 2000 when the burly hurler went 20-8 with a 4.11 earned run average earning a 4.8 WAR in 35 starts. He finished third in AL Cy Young voting only behind Pedro Martinez and Tim Hudson.
During his 21-year career, Wells totaled an impressive 53.8 WAR in 660 career games on the bump.
