Chase Headley hit a walkoff homer in the bottom of the 10th as the Padres topped the Pirates 7-5 on Tuesday. Headley also had a single to go along with his two-run homer off Daniel McCutchen to end it. Headley has 21 homers this season. He's the first Padre other than Adrian Gonzalez to hit 20 since Kevin Kouzmanoff finished with 23 in 2008. Besides Gonzalez, only Khalil Greene (27 in 2007) has hit 25 homers for the Padres since 2005.
