The Washington Nationals manager blew up at umpires after a controversial call went against shortstop Trea Turner during Game 6 of the World Series against the Houston Astros, and Martinez gave the umpire crew an earful.
After play continued, Martinez went out for more between innings and had to be restrained as umpires ejected him from the game.
Martinez — in considerably better spirits ahead of Game 7 after the Nationals prevailed on Tuesday — told reporters on Wednesday that a fan and a team doctor were concerned for his health during his outburst.
Martinez was hospitalized in September for a cardiac catheterization after feeling chest pains in the dugout during a game against the Atlanta Braves.
