On August 12, 2000 while a member of the Mets, Agbayani was involved in a particularly memorable play. In the fourth inning, with the Mets leading 1–0, the Giants loaded the bases after a double, an error, and a hit batsman. With one out, Giants catcher Bobby Estalella hit a fly pop to Agbayani in left field. Agbayani, thinking that the catch made three outs, gave the ball to a child, Jake Burns, in the stands and began to trot toward the dugout. Upon realizing his mistake, Agbayani sprinted back to the stands, pulled the ball from the hands of the young fan, Jake Burns he had given it to, and fired a throw toward home plate. Unfortunately for Agbayani, once the ball left the field, the play was dead, and all three runners were awarded two bases—causing Jeff Kent and Ellis Burks to score, and the Giants to take the lead, 2–1. The Mets went on to win the game, 3–2, and Agbayani gave another ball to the fan who had given the previous one back.
