The Brewers tied the game in the ninth inning when Yelich hit an opposite-field double off closer Aroldis Chapman and later scored on Sal Frelick’s base hit.

With a mighty swing, Yelich delivered a walk-off grand slam, sending a left hook to hanging Liam Hendriks slider, crushing it 400 feet to right-center field in the 10th inning to lift the Milwaukee Brewers to a dramatic, come-from-behind 5-1 win over the Boston Red Sox at American Family Field.
