While it was a pretty embarrassing play for Kepler, no beer league player makes that catch because they're ten feet from the ball when it drops. You're really underrating Kepler's speed and how quickly he was moving to get that ball. It was not an easy play to make because many right fielders don't get there in time. Kepler got there but he dropped the ball and that's on him. He's such a smooth player that while it really hurt to watch the ball drop, it's not something I expect to see often from him.
