SP5: Jim Clancy - 24.8 WAR
Jim Clancy was a solid pitcher for the Blue Jays during his tenure from 1977 to 1988. The big right-hander was known for his strong arm and durability, as he consistently provided stability to the teams' pitching staff during the infancy of the franchise. Clancy's ability to pitch deep into games and eat up innings is what his success was based around.
His lone All-Star appearance came in 1982 where he owned a 16-14 record with a 3.71 ERA and a league leading 40 games started. He recorded 128 victories, placing him third on the team's all-time wins list. His WAR with the team was 24.8, placing him fifth in the all-time rotation, mostly due to his longevity because Roger Clemens played just two seasons in Toronto and owned a WAR of 20.1. Clancy might not have been elite, but he was a good Blue Jay for the first 12 seasons of the franchise.
