SAN DIEGO -- Chase Headley, who made his Major League debut for the Padres in Chicago last week, was back in the starting lineup Tuesday night making his PETCO Park debut against the Orioles.

"The last five days have been pretty incredible starting with when Double-A [San Antonio] manager Randy Ready called me in the office and said he had to talk to me about something," Headley said. "Then, a couple hours later I was on a plane to Chicago and played the first three games at Wrigley Field. It's been pretty much an unexplainable five days."

While third baseman Headley went 1-for-10, he did see 44 pitches in 11 plate appearances and showed some patience at the plate and was steady in the field.

With Kevin Kouzmanoff still ailing with a lower back problem, Headley got to start his fourth straight game Tuesday. However, Padres manager Bud Black said that Headley would likely return to the Minors when Kouzmanoff is ready to go, which could be during this six-game homestand.

Headley, like the Colorado Rockies' Todd Helton, is a University of Tennessee product.

"Todd's been a tremendous player throughout his career," said Headley. "Other than both of us going to Tennessee, I can't really draw too many comparisons yet. But maybe down the road that would be something very exciting to be compared to him.

"I'm just up here playing day-to-day. I'm not trying to think about what is going to happen in the future. I'm just going to come out here ready to play every single day that I'm here and try to help this club win a few games."

Headley has done his work to get to the Majors, putting on 20 pounds during the offseason.

"I just worked hard in the weight room, but the biggest thing I did was my diet or lack thereof," said Headley. "I was eating five times a day as much as I possible could, just to get the calories in. It was more so the eating better more than the lifting. I've always tried to lift pretty hard, but taking more calories really helped put on the weight."

The switch-hitting Headley was batting .357 with 13 homers in 227 at-bats at the time of his recall from the San Antonio Missions.

Headley's parents were at the game in Chicago where he got his first hit, and they have the baseball.

Asked about the biggest difference between the Majors and the Minors, Headley said, "I'd have to go with the food.

"I've had some great meals since I've been in the big leagues," said Headley. "Minor League spreads hadn't really filled me up as much as the Major League spreads have. I guess that would probably be the No. 1 thing that I have enjoyed so far."

Black backs Peavy All-Star start: Black offered his endorsement of Jake Peavy being the starter in the All-Star Game for the National League.

Asked if he wanted Peavy starting the July 10 All-Star Game, Black said, "If Jake is selected to be on the team and they chose him to start, I think it would be awesome.

"I want our guys to play," said Black. "It's a great honor."

The way the schedule looks now, Thursday, July 5, at home against the Marlins would likely be Peavy's last start before the All-Star Game, "if we keep the rotation as it is," Black said.

Black said he would not start Peavy on three days' rest to get him an extra start before the All-Star Game.

Injury updates: Brian Giles (bone bruise on his right knee) and Kouzmanoff (lower back soreness) are both making progress.

"I think Brian is going to increase his work load [Tuesday] a little bit from Chicago," said Black. "He's progressing. He'll be coming off the DL soon and will go on a rehab assignment."

"I'm going to go hit right now and then we'll go from there," said Kouzmanoff, "Just walking around today, moving around, I feel pretty good. We'll see when I get out there and swing.

"There is still a little soreness, but a lot of it has gone away. I mean, I feel good. Saturday, I hit in the cage," said Kouzmanoff. "It's noticeably better, day-to-day."

On deck: Padres right-hander Justin Germano (5-0, 2.36 ERA) will be trying to stay perfect when he makes his first career appearance against the Orioles in what will be his eighth start of the season. The Padres are 5-2 in his seven starts and Germano is 2-0 with a 2.65 ERA in three Interleague starts this season. Southpaw Erik Bedard (4-4, 3.64 ERA) will pitch for the Orioles. First pitch is scheduled for 7:05 p.m. PT.
