#7- Rogers Clemens- 20.1 WAR
It is no secret that Roger Clemens was a special talent but what he did in his two seasons with the Blue Jays is absolutely mind-boggling. Clemens won 41 games and posted a 20.1 WAR in only 67 games with Toronto.
The Blue Jays inked Clemens as a free agent at the conclusion of the 1996 campaign. The Rocket would dominate baseball in a Blue Jays uniform winning back to back Cy Young awards and posting his best ever WAR season in 1997.
In 1997, Clemens went 21-7 with a 2.05 earned run average while fanning 292 batters in 264 innings of work. Clemens would make 34 starts totaling an 11.9 WAR on the season. PED’s or not, this guy is a Hall of Famer.
The Rocket’s son, Kacy Clemens is an 8th round draft pick of the Blue Jays and finished last season in High-A ball in Dunedin.
Following the 1998 season, the Blue Jays would ship Clemens to the Bronx Bombers in exchange for David Wells, Homer Bush and Graeme Lloyd. Clemens would hang up his spikes after the 2007 season pitching for four teams spanning 24-years, he would compile an insane 139.0 WAR total.
