The Kansas City Royals will travel to Toronto for a four-game series against the Blue Jays without 10 players because they have not received the COVID-19 vaccination.

The vaccine requirement for border crossing into Canada will affect Andrew Benintendi, Whit Merrifield, MJ Melendez, Hunter Dozier, Brad Keller, Brady Singer, Michael A. Taylor, Kyle Isbel, Dylan Coleman and Cam Gallagher.

"At the end of the day, it's their choice," Royals president of baseball operations Dayton Moore said. "It's what they decide to do. And we've always been an organization that promotes and encourages individual choices. Unfortunately, some of this affects the team. We're disappointed in some of that, but we realize it's part of the game and part of the world we live in. We're just really looking forward to providing these players an opportunity who are getting a chance to play in Toronto."

Prior to Kansas City, the most players a team had missed in Toronto was four, and 25 total players had hit the restricted list due to being unvaccinated.
