Agbayani is also fondly remembered by Mets fans for two clutch home runs hit during the 2000 season, earning him the nickname "Hawaiian Punch" (after the popular fruit drink). On March 30, his 11th inning grand slam against the Chicago Cubs gave the Mets their first win of the season, and a split in the two-game series the Mets and Cubs played in Tokyo, Japan. (It remained the only regular-season MLB grand slam ever hit in Japan until Domingo Santana hit a grand slam for the Seattle Mariners vs the Oakland Athletics on March 20, 2019.) Later that year, on October 7, he hit a game-winning home run in the 13th inning of Game 3 of the National League Division Series against Aaron Fultz of the Giants. Agbayani also drove in the winning run in the only game the Mets won in the 2000 World Series.
