Problem: You're umpiring at third base in a game between Westwood and Brownsburg. A Westwood hitter lifts a looping fly ball down the left-file line and the Brownsburg left fielder races over and reaches for the ball as it's about to drop onto the field. As he makes a reach for the ball, his body is in fair territory, but the ball and his glove are in foul territory. The ball glances off his glove and lands in foul territory. Is the ball fair or foul? And why?
