10 years ago, Mike Piazza ate his words when a Mets reliever doubled off Randy Johnson

Dae-Sung Koo pitched all of 23 innings in MLB. Across 33 games, he took a total of two at-bats. But 10 years ago on May 21, 2005, he hit a double in one of the most joyous moments in recent MLB history.

At the time, Koo was 35 years old out of Nippon Professional Baseball -- where he'd never had a plate appearance. In his first at-bat ever, Koo wanted no part of the plate, standing halfway to the dugout -- the New York Times called it "anti-batting."

So, for Koo's second at-bat against the Yankees pitcher and future Hall of Famer Randy Johnson, expectations were low. And then he ripped off a double to the wall:

That is what a moment of pure joy looks like. 

You can imagine the reactions in the Mets' dugout. David Wright went bonkers. Mike Piazza, so sure of Koo's fate, promised, "If [Koo] gets a hit, I'll donate a million dollars to charity." After the game, Piazza told the New York Daily News, "It's going to be a significant amount (to charity) over the next 20 years."

Koo, who is currently playing in the Australian Baseball League, eventually came around to score on a bit of bold base running after a sacrifice bunt from Jose Reyes. The Mets won, 7-1.  

Then-manager Willie Randolph told the Times, "I'm going to use him as a pinch-hitter tomorrow." It's a shame he didn't follow through.
