For golf fans, the "shot heard round the world" is Gene Sarazen's double eagle on April 8, 1936 at the 1936 Masters. Sarazen holed a 235-yard shot with his 4-wood on the Par 5 15th hole at Augusta National.
Sarazen came to the 15th trailing by three strokes. He drove to about 230 yards from the green. His caddie suggested he use a 3-wood for his approach. Instead, Sarazen used his 4-wood, and without a practice swing, he struck the ball. The ball landed on a flat spot just beyond the water hazard, bounced onto the green, and veered right to left before finding the hole.
This incredible shot tied him with Craig Wood at six under par, forcing the Masters' only 36-hole playoff, which Sarazen won.
To this day, no one else has double eagled the 15th hole at Augusta in Tournament play.
