Winners of six of their last seven and four straight, the Padres will try to win a fifth consecutive game Wednesday in Philadelphia for the first time since mid-June, when the club won seven in a row to move two-games above .500.
Standing in San Diego's way will be Phillies left-hander Cliff Lee, who was originally supposed to start Thursday before the club decided to give Roy Halladay an extra day's rest due to flu-like symptoms.
"I think he lost a lot of strength for a couple days there," interim manager Ryne Sandberg said of Halladay. "He actually went home the first day with it. He's feeling much better."
Because of an off-day on Monday, however, Lee will still be on normal rest when he takes the mound Wednesday. The last time the 35-year-old started, he took down the Braves by tossing eight dominant innings, allowing just one run on two hits while striking out 10 as the Phillies won, 2-1.
Opposing Lee for the Padres will be left-hander Eric Stults, who will try to bounce back from one of his worst outings of the year his last time out. The southpaw surrendered seven runs on nine hits over just 4 2/3 innings against the Giants.
"He just wasn't making pitches consistently," Padres manager Bud Black said after the game.
Boding well for Stults is the fact that he pitched well earlier this year against the Phillies, allowing two runs over seven strong innings back on June 24.
Before the game on Wednesday, the Phillies will hold a ceremony commemorating those lost on 9/11. The Philadelphia Police and Fire Departments will do the honor of presenting all 50 state flags on the field.
All on-field personnel, including players, coaches and umpires, will wear an American flag patch embroidered on the side of their caps.
Padres: Medica could debut Wednesday
The Padres still aren't quite sure what to make of first baseman Tommy Medica, who on Sunday was helping the Double-A San Antonio Missions advance in the Texas League playoffs.
They're about to find out, though. Padres manager Bud Black said there's a good chance Medica could get his first start Wednesday.
"There's a little something in his bat," Black said. "We think here in September that he brings us another bat on the bench. He'll get some starts, too. We're looking forward to getting him into the lineup. We feel as though he's deserving of this."
Medica hit .296 with 20 home runs, 65 RBIs and 45 extra-base hits this season between five games in the Arizona League and 76 games with the Missions.
Phillies: Rupp collects first big league hit
Cameron Rupp rose steadily through the organizational catching ranks this year, and he got his reward Tuesday against the Padres at Citizens Bank Park, starting behind home plate and collecting his first Major League hit in the eighth inning.
Rupp hit a combined .258 with 16 doubles, one triple, 14 home runs and 45 RBIs in 94 games between Double-A Reading and Triple-A Lehigh Valley.
"I'm anxious to see where he's at," Phillies interim manager Ryne Sandberg said before Tuesday's game. "I haven't seen him catch at all. It'll be the first time. I know that he's come a long way and he's developed a lot, so I'm anxious to see him work behind the plate and swing the bat."
Rupp ended up going 1-for-4 on Tuesday with a run scored.
• The Padres opened their third and final 10-game road trip of the season on Tuesday with an 8-2 win over the Phillies.
• Since 2004, Philadelphia has gone 44-20 vs. San Diego.
