The 34-year-old Pierre, who started in left field, batted second in the lineup and had an infield single in the second inning off Pirates starter Charlie Morton. Pierre advanced to second on a single by Shane Victorino, but he was subsequently picked off second by Morton.
The 35-year-old Podsednik, who started in right field, batted sixth in the lineup and had a sharp single to right field after Carlos Ruiz led off the second inning with a single. Ruiz and Podsednik moved up a base after a sacrifice bunt by Tyson Gillies, but both were stranded after Pete Orr stuck out and Michael Martinez grounded out.
Pierre and Podsednik were signed to Minor League deals to add depth to the outfield.
"They're going to start getting a lot more playing time so now's the time for them to show what they can do," manager Charlie Manuel said.
