CHICAGO (Ticker) -- Randy Wolf made the new-look Chicago Cubs ' offense seem rather ordinary.

Wolf tossed a four-hitter for his sixth career shutout and Ricky Ledee and Jim Thome homered as the Philadelphia Phillies posted a 3-0 victory over Kenny Lofton , Aramis Ramirez and the Cubs.

After failing to make it out of the seventh inning in each of his last six starts, Wolf (11-5) went the distance in this one, scattering two singles and two doubles. The lefthander walked three and struck out four en route to his second shutout of the season and first career win at Wrigley Field in five appearances.

"In this ballpark, you don't take anything for granted," Wolf said. "After Thome hit his home run, I really was able to bear down and just try to go through the order one at a time. Pitching a shutout in this park is not that easy."

"That's what an ace is all about," Phillies manager Larry Bowa said. "Randy is our stopper. When you come into Wrigley Field and throw a shutout against a team like the Cubs with their offense, you've really pitched your butt off."

Ledee gave Wolf all the support he needed in the second inning, belting a one-out solo home run. Thome added insurance in the third, blasting a two-run shot to surpass 1,000 RBI in his career.

"I grew up a Cubs fan living in Peoria, Illinois. My parents were here to watch me play in this park for the first time," Thome said. "I can't tell you how emotional it was to hit a home run in front of them here, and also get my 1,000th RBI on the same night."

"When you make a few mistakes like I did tonight, you're not going to win too many ballgames," Cubs starter Matt Clement said. "Thome hit a pitch I wish I could have back".

Thome's homer was his 360th, moving him into a tie for 57th place on the all-time list with Gary Gaetti .

Acquired from Pittsburgh on Tuesday, Lofton and Ramirez combined to go 0-for-8 with a strikeout and an error. Mark Grudzielanek was the only Cub to solve Wolf, stroking two doubles and a single.

"You might say our hitters were flat, but you would be wrong tonight," Chicago manager Dusty Baker said. "Wolf pitched a great game. This guy is an All-Star, and he showed why tonight."

"Ramirez and I traveled quite a bit to get here on time today," Lofton said. "We were playing pretty much on adrenaline. That's not to take anything away from Wolf, who pitched a great game, but I think after a good night's sleep, both of us will be fine, and we'll start helping this team more tomorrow."

Clement (7-9) allowed just three runs and three hits but walked five in seven innings. The righthander, who fell to 6-3 lifetime against Philadelphia, also had five strikeouts.

After getting Placido Polanco to ground into a double play to erase Marlon Byrd 's leadoff single in the first, Clement ran into control problems. Thome and Bobby Abreu drew walks before Clement uncorked a wild pitch. Mike Lieberthal walked to load the bases, but former Cub Tyler Houston grounded to first to end the threat.

The Cubs had an opportunity in the bottom of the inning when Grudzielanek doubled and took third on right fielder Abreu's error. But Wolf fanned Sammy Sosa and induced a groundout by Eric Karros around a walk to escape unscathed.

Ledee's eighth homer in the second gave Philadelphia a 1-0 lead before Chicago attempted to tie the game in the bottom half.

With one out, Alex Gonzalez walked and Damian Miller reached on an error by third baseman Houston. Clement failed to execute a sacrifice, popping up a bunt for the second out, and Wolf struck out Lofton to maintain the shutout.

Grudzielanek opened the third with a double but was thrown out at third trying to advance when a pitch by Wolf got away from catcher Lieberthal.

"Wolf kept us off balance all night," Grudzielanek said. "I had some success with his breaking ball, taking it the other way. He was definitely tough out there. Give him credit for the win."
