HOUSTON -- Braves third baseman Chipper Jones left Tuesday's 4-2 win against the Astros in the sixth inning after fielding Hunter Pence's grounder down the third-base line and making a leaping throw across his body for the out at first.

After the throw, Jones landed awkwardly and was on the ground for a few minutes. He eventually limped off the field with help from Braves trainers and was replaced by Brooks Conrad. Jones, who tore his ACL in 1994, said he didn't think he tore it again.

"I don't think it's my ACL because when I did it before it sounded like my knee exploded," Jones said. "While I did hear a pop, it wasn't the same pop."

Jones will get an MRI in Atlanta on Thursday to see what the exact diagnosis will be. Jones said he received all of the ACL tests after the injury.

"I have a lot of pain in the left side of my knee," Jones said. "I don't know what that means. Hopefully it's just a sprain."

Jones added that his knee isn't swelling as much as it did when he tore it the first time and he doesn't have as much fluid as he did then either.

Jones had entered Tuesday's game on a tear, hitting .361 over his past 10 games. Manager Bobby Cox said losing Jones for an extended period of time would be tough.

"I hate to see it because he's playing so good right now," Cox said. "It's about as good as I've seen him swing the bat in two years."

Heyward out of lineup due to sore knee

HOUSTON -- Braves right fielder Jason Heyward was scratched from Tuesday's lineup with a sore right knee.

Heyward, who hit a homer on his 21st birthday on Monday, was replaced by Melky Cabrera, who moved over from center field. Outfielder Rick Ankiel then came on to fill in for Cabrera at center.

Heyward is considered day to day. Shortstop Alex Gonzalez moved up from eighth to second in the order.

Wagner has fond memories of Houston

HOUSTON -- With Billy Wagner set to retire after this season, he's making his last stop in Houston. Wagner began his career with the Astros and played for them for nine seasons. He said he will always have fond memories of his time with the Astros.

"When you're put in an organization that takes care of your players, it makes it easier," Wagner said. "I always enjoyed my time here and didn't want to leave."

Wagner led the Astros to the playoffs multiple times playing with former teammates Jeff Bagwell and Craig Biggio.

"The experience was really good," Wagner said. "Baseball was exciting in Houston and wherever you went you were recognized. You just really enjoyed playing here."

With the Astros' recent trades of Lance Berkman and Roy Oswalt, Wagner said he facing a much different team than the one that he's used to.

"I don't know anybody over there really," Wagner said. "It makes it tougher to face these guys."

After debut, Minor feels like he belongs

HOUSTON -- With his first Major League start in the books, Mike Minor can appreciate it a little more. After he threw six innings and gave up three runs in a no-decision on Monday, Minor said he's ready for his next one.

"I feel like it was a good first start," Minor said. "Looking back on it today, it's pretty tough out there, but I think I belong there."

Minor said he's glad that his first start is over because he won't have as much anticipation that came with his first one.

"Yesterday I was sitting here five hours before the game and it was the longest five hours of my life," Minor said.

While he can rest on his days off, Minor said he looks at the preparation that veterans Derek Lowe and Tim Hudson put in on their off-days. This can include watching film as well as treating his body right.

"What you don't see is the stuff they do with the film," Minor said. "Everyone has the stuff to be here but it's the work you put [in] that really pays off."
