The Brewers hit Cubs outfielder Ian Happ in the eighth inning in his left knee as he had to leave the 9-0 game on Saturday afternoon.

The Cubs appeared to support Happ as Keegan Thompson hit Andrew McCutchen as payback.

After the hit batter, both teams ran onto the field and had a heated exchange, but nobody was ejected besides Thompson.

The Brewers have hit three Cubs players today, including Willson Contreras, on back-to-back days to start the season.
