Carlos Delgado hit his second homer of the game moments after Jose Reyes provoked excitable reliever Armando Benitez to balk home the tying run in the 12th inning, and the Mets startled the Giants 5-4 Tuesday night. The Mets took advantage of two balks by Benitez to win their fourth in a row. Minus Barry Bonds from the starting lineup, the Giants lost their fourth straight game.
