Matt Olson is one of the better defensive first baseman in baseball, but even he is prone to some pretty bad mistakes. The A's first baseman made a pretty egregious gaffe during Friday night's contest, somehow misplaying a slow-roller from Max Kepler.
This is the MLB equivalent of dropping a wide open screen pass in football. There was simply no excuse for Olson not to come up with the ball, as it would have ended the inning for Oakland, stranding a pair of base runners.
Instead, one run scored on the play, and what Max Kepler thought was a weak groundout resulted in runners on the corners and the inning staying alive.
