DENVER -- Phillies right-hander Roy Oswalt made what is expected to be his final rehab start Monday. He gave up seven hits and two runs in six innings for Triple-A Lehigh Valley, with two walks and four strikeouts. Oswalt got 10 outs on ground balls.

Oswalt has been on the 15-day disabled list with lower back inflammation since June 24 -- his second such stint on the DL this season.

He is expected to go back into the Phillies' rotation this weekend in place of Kyle Kendrick, who is scheduled to start Tuesday against the Rockies. Kendrick, who has made 10 starts and 15 relief appearances this season, will go back to the bullpen.

Manuel speaks on Phillies' bullpen, Pence

DENVER -- The Phillies made a huge acquisition Friday, getting right fielder Hunter Pence two days before the non-waiver Trade Deadline from the Astros.

For a first-place club still trying to fend off the Braves and vie for the National League's best record, it was a welcome move.

"I look at our club right now, and I'm very happy with it," said Phillies manager Charlie Manuel. "We could still use a bullpen piece, but I'm not so sure that bullpen piece [isn't] in our Minor Leagues. We got two or three good young prospects down there.

"I'm not saying we have to go make another big trade. I'm just saying [making an acquisition] for depth in our bullpen."

Trade Include

Manuel said he was concerned about relievers Michael Stutes, who has pitched 37 2/3 innings in 37 games since he came up from Triple-A on April 25, and left-hander Antonio Bastardo, who has eight saves while pitching 40 1/3 innings in 44 games, because both are "getting into new territory."

Pence gives the Phillies the right-handed bat they have been seeking since Jayson Werth left for Washington as a free agent in the offseason.

"Jayson Werth takes more pitches [than Pence]," Manuel said. "He hits real good when he's smooth and stays behind the ball and catches the ball out front. This guy's a different hitter because he hacks."

Manuel called Werth more of a technique hitter with better balance than the aggressive Pence.

"[Pence will] hit balls on the inside part of the plate to right field, and sometimes he'll hit balls out away from him to left-center," Manuel said. "He hits the ball all over the field. He's not what you call a real disciplined-type hitter, but he makes contact good enough. He makes contact often. He doesn't strike out as much as Jayson."

Halladay has special fan for start in Denver

DENVER -- Roy Halladay, who grew up in the Denver area, is slated to start the Phillies' series finale with the Rockies on Wednesday. For Halladay, who is 13-4 with a 2.44 ERA, it's no big deal to start at Coors Field.

"It's no different. It's another start," Halladay said. "But I look forward to coming here and seeing my family, and baseball is separate."

Halladay wasn't involved in the decision on May 12, 2010 -- his lone start at Coors Field -- when he allowed 10 hits and three runs in 6 1/3 innings in the Phillies' 4-3 10-inning loss.

"Either way, it doesn't matter," Halladay said of whether or not his turn in the rotation comes while the Phillies are in Colorado. "The sooner, the better."

One of Halladay's well-wishers, who is not family in strict sense, is Helen Campbell. Her husband, Bus, who died in 2008, was a longtime pitching instructor in the Denver area.

Campbell began working with Halladay when the right-hander was 14. He was an associate scout for Toronto when the Blue Jays took Halladay 17th overall in the 1995 First-Year Player Draft out of Arvada West High School in suburban Denver.

Halladay spoke regularly with Bus Campbell between starts and said Helen Campbell will watch him pitch on Wednesday.

"She was always there," Halladay said. "She was great to me, and it's good to be able to see her when we come back."

Lidge feeling healthy, ramping up velocity

DENVER -- Reliever Brad Lidge, who made his 2011 debut for the Phillies on July 25, threw 23 pitches in Sunday's 6-5 win over the Pirates in his fourth outing, three fewer than he threw in his first three appearances combined. He gave up one run on a hit and a walk in one inning.

Lidge began the season on the disabled list with a right posterior rotator cuff strain.

"The good news is I feel healthy, and even after throwing 23 pitches, I'm bouncing back well," Lidge said. "Obviously, when you're getting your feet wet and getting back into the shuffle of things, one of the big factors is in more intense games, as opposed to Minor League rehab outings, are you able to bounce back?"

Lidge made eight rehab appearances between low Class A Lakewood and Double-A Reading, and he said it's easier in the Minors to put the ball where you want and not get that amped up. It's different in the big leagues.

"The intensity goes up, you want to put more on the ball," Lidge said. "So you have to regain the control at the Major League intensity level. Fortunately, my slider's done that. My fastball's not quite there the way I'd like it to be yet."

Worth noting

• According to the Elias Sports Bureau, Raul Ibanez became the first Phillies player to have a walk-off RBI in a game in which he already hit two home runs -- accomplished in the Phillies' 6-5 win over the Pirates on Sunday -- since Hall of Famer Mike Schmidt homered twice and had a walk-off walk against Atlanta in the first game of a doubleheader on July 25, 1980.

Ibanez is the first Major League player to accomplish this feat since Tampa Bay's Carlos Pena did it against Texas on Aug. 22, 2009.
