Catcher Erik Kratz got Eugenio Suarez looking on a 59-mph knuckleball

Very quietly, Eugenio Suárez has been one of the best hitters in baseball this year. Through 65 games, Cincinnati's third baseman had slashed a blistering .303/.387/.570 with 16 homers and a league-leading 60 RBIs. But during Saturday's 12-3 win over the Brewers, Suarez was no match for Erik Kratz -- yes, we said Erik Kratz, Milwaukee's backup catcher.
To be fair, not every backup catcher has a knuckleball like this:

"We don't want to wear anybody else's arms out," Kratz told MLB.com's Adam McCalvy after the game. "So if it can get some guys fresh so we can use them tomorrow or the next day, I definitely take pride in that."
That's not even Kratz's first Major League strikeout -- he made two pitching appearances back in 2016, one with the Astros and one with the Pirates, and recorded a K with Pittsburgh. Does one of baseball's best bullpens happen to have an opening?
