It was widely documented how bad the Toronto Blue Jays bullpen was in August. To quickly recap from August 1 through September 3, the Blue Jays bullpen had an ERA of 4.98. In 103 innings pitched they allowed 65 runs (57 earned runs), 11 home runs a 4.34 FIP, and allowed a .312 BABIP.
Those were worrisome numbers for a team that made the bullpen their biggest priority at the trade deadline. They acquired two relievers in Seranthony Dominguez and Louis Varland to be middle-to-late inning options. They also acquired a starter in Shane Bieber to come into their rotation which in theory should have let one of their five arms slide into a swing-man / long relief role to add even more depth to the bullpen.
