A baseball fan threw a beer can at Baltimore Orioles outfielder Hyun Soo Kim during the seventh inning of Tuesday's American League wildcard game.
With the score tied 2-2, pinch hitter Melvin Upton hit the ball to left-field.
Kim made the catch despite the can narrowly missing him as it came out of the stands.
