Peterson makes first start at third base

WASHINGTON -- Rookie infielder Jace Peterson saw a few more pitches on Saturday than he did in his Major League debut on Friday.

Peterson saw exactly two pitches in his debut in the Padres' 11-1 loss to the Nationals. He singled on the first pitch he saw from Nationals' starting pitcher Stephen Strasburg in the seventh inning, before he flew out to center field in the ninth inning.

"I was looking for a fastball to hit, and it happened to be on the first pitch," Peterson said after Friday's game.

Peterson, who was added to the 25-man roster from Double-A San Antonio before Friday's game, got his first Major League start at third base on Saturday against the Nationals.

Peterson -- who is filling in for Chase Headley, who landed on the disabled list with a strained right calf -- is the fourth player in franchise history to get his first Major League hit on the first pitch he saw. The others were Sean Kazmar (Aug. 13, 2008), Craig Stansberry (Aug. 25, 2007) and Humberto Quintero (Sept. 3, 2003).

Peterson went 0-for-3 in Saturday's 4-0 loss to the Nationals.
