When backup catchers are called into action, they are often only relied upon to give the starter rest. When the Chicago Cubs put Taylor Davis in the lineup on Saturday, the 29-year-old did even more.

The St. Louis Cardinals clearly didn’t fear Davis’ hitting prowess since they walked Kyle Schwarber to load the bases just to face Chicago’s backup catcher. The minor-league veteran made them pay for it immediately.

He unloaded a towering blast deep into the stands for the first home run of his career and a game-changing grand slam for the Cubs.

Davis has played in 572 career games in the minor leagues with just 17 appearances in the majors, so Saturday’s grand slam had to feel even more special for a player who earned it

The game-tying grand slam gave the Cubs a huge boost and could be just what they need to turn the game around and grab a win against one of the top teams in baseball. Of course, it all happened thanks to a Willson Contreras receiving a day off and Davis getting an opportunity.
