On June 29, 2009 In Milwaukee, 3B Casey McGehee plays both the goat and the hero. In the top of the 6th, his drop of a routine pop fly leads to two New York runs; in the bottom of the inning, he hits his first career grand slam; in the 7th, he takes his time fielding a ground ball off the bat of Gary Sheffield, leading to an infield hit and another run; he is then removed in a double switch. Still, the Brewers bang out 19 hits, including 4 by J.J. Hardy and 3 by Jason Kendall, for a 10 – 6 win. With the loss, the Mets fall below .500.
