With the bases loaded and one out in the first, Willingham hit a drive off the center-field wall that bounced back onto the field of play. Two runs scored easily, before Adam Dunn barreled into Mets catcher Rod Barajas, plating a third run and knocking the ball loose in the process. That prompted Willingham to also attempt to score, though Barajas managed to recover and tag him out -- for a time.
After a brief video review, umpires ruled that the ball hit just to the right of the orange line in center field, indicating a home run. The hit was just the third grand slam Santana had ever allowed.
