PHILADELPHIA -- The Philadelphia Phillies may have found a fifth ace.
Worley (2-0) allowed one run and four hits, striking out a career-high seven in his fourth start in the majors. Worley is filling in for the injured Joe Blanton.
The 23-year-old righty has allowed just one run and six hits in 12 innings in his two starts since coming up from Triple-A Lehigh Valley. He already has as many wins as Cliff Lee, one member of Philadelphia's star-studded pitching staff. Roy Halladay and Cole Hamels both have four wins and Roy Oswalt has three.
"I'm just trying to contribute the best I can," Worley said. "Some things are going my way."
Despite his two impressive starts, Worley is likely going back to the minors once Blanton returns from the disabled list. He's making quite an impression while he's here.
"He's been very good," manager Charlie Manuel said. "He has good stuff, keeps his composure and he's focused on what he's doing. He's shown he can pitch."
The NL East-leading Phillies have won 10 of 13.
Jason Marquis (3-1) gave up 10 hits and six earned runs in five-plus innings in his worst start of the season. His ERA rose from 2.62 to 3.66. Marquis was seeking his 100th career win and was trying to go 4-0 for the first time.
"I was leaving balls up," Marquis said. "If I got it down, I got the contact I wanted."
Ibanez snapped an 0-for-35 slump with two doubles on Tuesday and is now 5-for-7 since the skid.
Ibanez gave Philadelphia a 1-0 lead when he connected on the first pitch from Marquis in the fifth. Ibanez hit a high drive deep into the seats in right center.
"I feel better at the plate, starting to feel more comfortable and seeing the ball better," Ibanez said.
Adam LaRoche hit an RBI double to cut Washington's deficit to 3-1 in the sixth, but Philadelphia chased Marquis with four runs in the sixth.
On a chilly night at the ballpark, a crowd of 44,123 made it 152 straight sellouts in Philadelphia, including postseason play.
Nationals manager Jim Riggleman was ejected in the fourth when he came out after LaRoche was upset with a called third strike. LaRoche dropped his bat at the plate and had a few words for umpire Alfonso Marquez, so Riggleman left the dugout and got the quick ejection.
"Adam doesn't say anything. He's quiet," Riggleman said. "So if he complained, I felt I had to."
J.C. Romero pitched a scoreless seventh for the Phillies in his first appearance since going on the disabled list April 19 with a right calf strain.
The Nationals said Michael Jacob Allen, the stepson of Davey Johnson and son of Susan Johnson, died Tuesday at 34 from infection and pneumonia in Orlando, Fla. Davey Johnson is the senior adviser to general manager Mike Rizzo. ... Nationals outfielder Jayson Werth went 1-for-4 against his old team. ... Nats left fielder Michael Morse was a late scratch because of right knee soreness. Laynce Nix took his place in the lineup. ... Brian Schneider was 1-for-25 off Marquis before hitting a single in the fifth. ... Washington's Matt Stairs singled in the ninth for his 100th career pinch-hit, most among active players. ... Manuel said catcher Carlos Ruiz is expected to take batting practice Thursday. Ruiz hasn't played since April 27 because of lower-back tightness but wasn't placed on the DL.
