PHILADELPHIA -- Enter Endy Chavez. Exit Brian Lawrence.

The Mets activated Chavez before Tuesday's game and optioned Lawrence to Triple-A New Orleans. Chavez is recovered from a strained left hamstring in June. He played nine innings of Binghamton's 14-inning victory over Trenton on Monday, finishing 0-for-3 with two walks.

But it was more satisfying for Chavez to see his name written in the Mets' lineup rather than a rehabilitation game.

"I'm happy and I'm ready to be on the field, to do the things I used to do," said Chavez, who batted eighth and started in right field. "I see myself back to life again."

In six rehabilitation games with rookie league Gulf Coast, Class A St. Lucie and Binghamton, Chavez was 11-for-23 with one double, six RBIs and five runs scored. What Chavez also added was speed and defense, two things Mets manager Willie Randolph said he missed.

"Those are very important elements," Randolph said.

While Chavez was thrilled to be back, Lawrence (1-2, 6.31 ERA) was obviously discouraged after giving up 10 hits and five earned runs in 4 2/3 innings on Monday.

"I'm disappointed in the last couple of games," Lawrence said after the loss. "My game is, 'Keep the ball on the ground,' and I feel like I've done that. It's just the ball has gotten through the infield and found some holes. That's frustrating to me."

Lawrence echoed similar thoughts in the clubhouse Tuesday after he learned of the decision.

"It wasn't a surprise," he said. "I didn't pitch great. It didn't help things. But I can get outs here. I've shown that. I've made mistakes but I'm getting better."

There's a distinct possibility that Lawrence could rejoin the Mets when rosters expand on Saturday.

"He'll be back," Randolph said. "Brian did a nice job for us. Brian held his own pretty well, kept us in games, for the most part."

Thomas 'K' Glavine: With five weeks remaining in what likely is his final season, Tom Glavine seemingly has little chance of moving closer to the top of the list of career victories. He had 301 before his start against the Phillies on Tuesday night. Mickey Welch is next on the list, in 20th place, with 307. Glavine probably has six starts remaining.

He continues to move up the list of career strikeouts, though. Glavine moved into sole possession of 27th place when he struck out Jayson Werth in the second inning Tuesday. He had been tied with Jerry Koosman at 2,556.

If Glavine gets to 2,584 -- not likely -- he will have three more strikeouts than Bob Feller and one more than Warren Spahn, his father's hero.

Trade winds: Mets general manager Omar Minaya is always looking to add another player to bolster the club's depth.

On Aug. 20, the Mets acquired Jeff Conine from the Reds for Minor Leaguers Jose Castro and Sean Henry. Could another deal take place before Friday, the last day a player would be eligible for postseason play?

"Something may show up," Minaya said. "But most of the guys have been getting claimed."

Rare hook: David Wright was surprisingly tossed from Monday's game in the top of the ninth inning by home-plate umpire C.B. Bucknor. Wright had questioned Bucknor's strike zone in two at-bats and was ejected while sitting in the dugout.

It was only the second time Wright had been ejected.

"It's over," Wright said. "Slight philosophical difference. It's forgotten."

Saturday starter: When Lawrence was optioned out, it left a vacancy for Saturday's starting pitcher in Atlanta. It could be Mike Pelfrey. It could be a couple of other players at Triple-A. But it won't be Pedro Martinez just yet.

"Most likely, it's going to be something internal," Minaya said.

Martinez is expected to make at least one more rehab start before his long-awaited Mets seaon debut, likely to be either Sept. 7 or 8 against the Astros.

Extra bases: Catcher Ramon Castro's sore lower back is likely to keep him sidelined after the rosters expand. ... Outfielder Carlos Gomez had a rehabilitation game Sunday night at St. Lucie and went 0-for-3. He has missed almost two months with a fractured bone in his left hand. ... Relief pitcher Ambiorix Burgos (sore elbow) was scheduled to undergo Tommy John elbow ligament replacement surgery, according to Minaya.

Coming up: Left-hander Oliver Perez (12-8, 3.34 ERA) gets the start for the Mets on Wednesdy at 7:05 p.m. ET. Perez will face 44-year-old lefty Jamie Moyer (11-10, 5.16 ERA).
