It’s a Midwest showdown as Kansas City looks for their first series win of the season this afternoon against the Brewers in Milwaukee. The Royals won in a blowout Monday before their bats were silenced in a 5-0 loss yesterday to even the series.

In the 10th, Royals closer Carlos Estévez came on from the bullpen. He threw a wild pitch and allowed a double to Brewers star Jackson Chourio. Eventually, the score was tied, 2-2, with runners at first and second and no one out. Then, one moment caught the attention of home plate umpire John Tumpane, who called a balk on Estévez. What happened?
