Koo’s most memorable moment as a Major Leaguer occurred on May 21, 2005, when he recorded his only major league hit, a double off of Randy Johnson of the New York Yankees. This came right when Fox TV analyst Tim McCarver commented on how Koo’s plate appearance was “the biggest give-up at bat”. Koo had taken two pitches and struck out in his first at-bat, leading everyone to believe that he was ready to go up just to sit down again. On a 1-and-1 count, Koo crushed a deep line drive right over Bernie Williams’s head one hop off the wall in right-center field. Upon reaching second base, the home crowd and his teammates in the dugout cheered and chanted “KOOOO!” When asked about what he thought about the hit, Koo responded, “Other people say that I swung my bat with my eyes closed. But, of course I saw it –I hit it! It has been 18 years since I batted last – when I was in high school. Occasionally I went to the batting cages and swung the bat a couple of times. But, there really wasn’t any difference.” A slow runner with little base running experience, Koo advanced to third base on a sacrifice bunt dropped by the following hitter, José Reyes. However, after Koo slowed down approaching third base, he re-accelerated and ran towards a vacant home plate left uncovered as Reyes was getting thrown out at first base. Yankees’ catcher Jorge Posada promptly ran towards home in a foot race with Koo. Upon retrieving the thrown ball from first base, Posada applied the tag onto Koo’s left shoulder as he slid head first towards home plate on a close play. Home plate umpire Chuck Meriwether called Koo safe on the play. With that, the home crowd once again cheered and chanted his last name. His teammates enthusiastically greeted him, with celebrations ranging from his teammates brushing the dirt off his uniform to Doug Mientkiewicz fanning him with a towel. On his reception by his teammates, Koo said that “they said a lot of things. I just couldn’t understand what. I think they were saying ‘Good job.'” It was his final Major League at-bat.
