Input: Question: Which pitcher that opened the series was older? Passage:The Giants opened the series with Jake Peavy on the mound to counter Nationals starter Stephen Strasburg. Joe Panik put the Giants on the board in the 3rd inning with an RBI single and Brandon Belt followed suit in the 4th to support Peavy, who didn't allow a hit until the bottom of the 5th inning. The first signs of trouble for the Giants came in the bottom of the 6th when, after a leadoff double from former Giant Nate Schierholtz and a two-out walk to Jayson Werth, Peavy was taken out of the game. Javier López came into the game only to surrender a walk to Adam LaRoche. With the bases loaded, Hunter Strickland came on to make just his tenth overall Major League appearance and struck out Ian Desmond to end the threat. The Giants added a 3rd run when Panik tripled to lead off the 7th, and Buster Posey singled to knock him in. This run was to prove crucial, as when Strickland came out in the bottom half of the inning, he allowed home runs to both Bryce Harper and Asdrúbal Cabrera to make it a one-run game. Jeremy Affeldt finished off the Nationals in the 7th and Sergio Romo pitched a scoreless 8th, before Santiago Casilla retired the side in order for the save, as the Giants held on to win by a score of 3-2.
