Boston Red Sox closer Tanner Houck's decision to remain unvaccinated against COVID-19 means he is not currently allowed to play games against the Toronto Blue Jays north of the border.
His absence was felt in a huge way on Tuesday as the Red Sox blew a ninth-inning lead and fell to the Blue Jays in walk-off fashion.
After grabbing the lead in the eighth inning, Boston manager Alex Cora turned to right-hander Tyler Danish for the home half of the frame, then left him out to begin the ninth. After allowing the first two batters to reach, Hansel Robles replaced Danish on the mound and served up back-to-back RBI singles to Bo Bichette and Vladimir Guerrero Jr.
