The Baseball Zealot notes that Jacoy Ellsbury has a great vertical leap.

When I was a freshman in high school (Central HS, Bridgeport, CT) out basketball team won the state championship. Our tallest player was 6' 3", but they all could out jump taller players. This was the era before possession arrows, so there were plenty of jump balls. Our players would coil themselves close to the floor, which gave them extra power (think of the way Rickey Henderson generates power uncoiling from his crouch). They easily won jumps against players two or three inches taller.

They also won the states on a buzzer beater after trailing by 10 with five minutes to go in the game.
