Boston didn’t indicate why Houck and Crawford were placed on the restricted list ahead of the team’s four-game series against the Blue Jays in Toronto. Prior to the start of the 2022 season, Canada’s restrictions on allowing individuals unvaccinated against COVID-19 into the country led MLB and the MLB Players Association to agree to permissible roster modifications for games in Toronto.
Houck has stated publicly that he is not vaccinated against COVID-19. Boston will need to find a replacement for the 25-year-old when his next turn in the rotation comes up on Thursday.
Houck came out of the bullpen on Sunday and threw 1 2/3 perfect innings against the Rays, lowering his ERA to 2.87 over four games (three starts) this season.
Crawford owns a 9.00 ERA over five relief appearances. He has 11 strikeouts and six walks in seven innings.
