On May 12, 2004 — In one of the most remarkable at-bats in major league history, Alex Cora fouls off 14 consecutive pitches and then hits the 18th pitch over the right field fence for a two-run home run off Cubs pitcher Matt Clement. The homer extends Los Angeles’s lead to 4 – 0. The Dodger Stadium crowd cheers each foul ball as the total starts to be displayed on the scoreboard.
