Unbelievably, it's at least the third time Adrian Houser has vomited during an MLB game.

I remember an NHL goaltender who vomited before every game and played for two decades.
Hockey Hall of Famer Glenn "Mr. Goalie" Hall was known for vomiting before most of his games, a ritual he believed helped him perform better. He felt that if he didn't experience this pre-game nausea, he wasn't giving his all to the team. This unusual habit was so well-known that the Chicago Black Hawks even kept a bucket on the bench for him.
Hall himself confirmed this habit in interviews, stating that he believed he played better if he was physically sick before a game. He described it as a way to "get wired" for the game and ensure he was pushing himself to his highest standard. According to one article, he would even drink a glass of orange juice after vomiting.
While it may seem strange, Hall's pre-game ritual was a well-documented part of his career, and he continued this practice throughout his time in the NHL.
