If you're not a professional baseball player, it's probably hard to impress a Major League Baseball player or coach. Not only are they the best baseball players on the planet, but they witness the athleticism of all the other best baseball players on the planet on a daily basis.
Even so, during the second inning of Monday's 2-0 win over the Padres, a Cardinals batboy made a leaping, barehanded catch on a Jose Martinez foul ball that managed to impress Cardinals players and coaches alike:
This catch wasn't only an impressive display of athleticism, but served the practical purpose of protecting the coaching staff from the flight of the foul ball. In terms of the quality of the effort, the reaction in the Cardinals dugout is all the necessary proof that this batboy made a spectacular play.
