#11- Josh Donaldson- 21.4 WAR
Josh Donaldson put up a ton of WAR in a short period of time with the Blue Jays, pretty amazing considering he battled injuries the past two seasons in Toronto. Donaldson rivals McGriff as a player who could be atop this list had he remained with the team for an extended period.
J.D. was acquired from the Oakland Athletics following the 2014 season, he would spend the next four seasons with Toronto before being shipped to Cleveland late last summer. From 2015 through 2016, Donaldson put up WAR totals of 8.5 and 7.6 over the course of two years with the Blue Jays. Those totals followed back to back campaigns in Oakland where he accumulated 7.7 and 7.5 WAR totals.
In 2015, Donaldson hit .297/.371/.568 with 41 homers, 123 runs batted in and 122 runs scored in 158 games. That stat line was good enough for his ridiculous 8.5 WAR and the AL MVP award.
Thus far, Donaldson sports an impressive 38.5 WAR career rating over 8 MLB seasons with three different teams. J.D. will attempt to channel his inner 2015 in his first season reunited with former GM Alex Anthopoulos in Atlanta.
