#10- Doyle Alexander- 13.6 WAR
The Blue Jays signed Doyle Alexander after the hurler was released by the New York Yankees in the summer of 1983. The pitcher would spend parts of four seasons in Toronto winning 17 games in consecutive campaigns.
The friendly confines of Exhibition Stadium seemed to bring the best out of Alexander, the veteran accumulated his two best WAR seasons while pitching north of the border. In 1984, Alexander went 17-6 with a 3.13 earned run average while putting up a 6.1 WAR in 35 starts. In 106 games with Toronto, the former 9th round pick of the Los Angeles Dodgers totaled a 13.6 WAR. Alexander ranks 10th on the Blue Jays all-time WAR list.
Alexander pitched in two forgettable postseason games for the Blue Jays in 1985. The Royals would obliterate the hurler for 10 runs scattered over 14 hits in 10.1 playoff innings. The Jays would eventually lose the ALCS series in seven games to Kansas City.
In the summer of 1986, the Blue Jays would deal Alexander to the Atlanta Braves for pitcher Duane Ward. Alexander would play for eight different teams compiling a career 34.7 WAR over the course of his 19-year career.
