The pitcher grabbed the wheel to keep the bus under control and avoid disaster.
Rustin Dodd of the Athletic provided additional details and a view of the windshield:
The team bus was traveling from the airport to their hotel in Toronto ahead of their series against the Blue Jays.
The driver, Fred Folkerts, sustained a cut on his face but his injuries were not considered serious. Meanwhile, Boyer gave him all the credit for remaining focused during the chaos.
"He was a stud," Boyer said of the driver, per ESPN. "That guy Fred was a trooper. He had shards in his face, and he was locked in on trying to get the bus slowed down."
The weather has been a major problem for the Royals in recent days. In addition to the problems in transit, the team had its game against the Angels Sunday postponed due to cold weather, while Monday's game was postponed due to damage to the roof at the Rogers Centre.
Falling chunks of ice from the nearby CN Tower reportedly caused the damage, per Alexandra Jones of the Toronto Star.
While the cancelations have been an inconvenience in the Royals' schedule, at least the team is safe thanks in part to Boyer's actions.
