He heard the broadcaster say David Wright made a diving stop at third, so Glavine opened his eyes to make sure the throw to first was on line and in time.
With his second diving stop of the game, Wright preserved New York's 4-3 win over the Philadelphia Phillies on Saturday, giving Glavine his first win since June.
"I know what's going on. I knew I hadn't won a game in a while," Glavine said. "You start hearing that stuff, and it starts getting in your head a little bit."
Ryan Howard hit a three-run, opposite-field homer to left in the first, but Glavine (12-4) didn't allow any more runs.
"It didn't look good for a while there," Mets manager Willie Randolph said.
Lieber led 3-1 and hadn't allowed a runner since the first when he fielded Carlos Beltran's check-swing grounder with two outs in the sixth and threw wildly to first for an error. The game turned on the next four pitches.
"I just have to make that play. I'm trying to get off the mound quick. I was trying to rush it," Lieber aid. "It's embarrassing."
Carlos Delgado singled up the middle, just past the outstretched glove of shortstop Jimmy Rollins, and Wright took a ball, then lofted a high drive to left field off the end of his bat. Frustrated he didn't make good contact, Wright didn't hustle out of the batter's box. But on a sunny, cloudless afternoon, the ball fell between Rollins and left fielder Pat Burrell for a single that scored Beltran and left runners at the corners.
"I should have caught the ball," Burrell said. "It was my play, and I didn't make it."
In the Phillies dugout, manager Charlie Manuel took off his cap and rubbed his head.
"Today we kind of beat ourselves," he said.
Wright knew he should have been on second, and when he got back to the dugout, he apologized to Randolph.
"I'm fortunate he didn't snatch me out of the game there," Wright said.
Chavez, who entered in the bottom of the first when Cliff Floyd left because of sore left Achilles' tendon, drove the next pitch off the fence in left-center to put the Mets ahead.
"I attacked the fastball and I was trying to be aggressive. I made good contact. It felt great," Chavez said. "It's hard when you know you're not in the lineup every day."
Glavine got 16 groundball outs, including two on Chris Coste's inning-ending double play in the sixth. Glavine had been 0-2 in seven starts since June 23, matching the third-longest winless streak of his career, according to the Elias Sports Bureau.
After allowing five hits in seven innings, he felt good about his performance.
"You start putting pressure on yourself to do some things," he said.
Aaron Heilman pitched a perfect eighth, and Wagner got into trouble and escaped once again for his 24th save in 29 chances.
Howard singled leading off the ninth before Burrell took a called third strike and Coste struck out swinging. Chase Utley pinch hit a day after the Mets stopped his hitting streak at 35 games, and singled to right to move the potential tying run to third.
Wright had made a diving backhand stop on Shane Victorino in the third and threw out Coste from foul territory in the fourth, with Delgado applying the tag. On this Wright, he made the backhanded stop on Lieberthal and threw to first to end it.
"You can't really practice it or teach it," Wright said. "It has to be a first-step reaction."
Wright's dives reopened a cut on his arm sustained in Florida earlier in the week.
"It's going to be sticking to the sheets tonight," he said.
New York, which had lost three of four, reopened a 12-game lead over the second-place Phillies in the NL East. Philadelphia, which had won four straight, lost for just the second time in nine games.
"This is a huge loss," said Lieber, who pitched a six-hitter for his first complete game since June 14 last year. "That's the bottom line."
- Floyd, held out of the starting lineup on July 30 because of the tendon, aggravated it when he unsuccessfully chased Aaron Rowand's foul in the left-field corner.
- Howard has four homers against the Mets this year.
- Jose Reyes doubled leading off the bottom of the first and scored on Lastings Milledge's single.
- Lieber has won once in nine starts since May 13.
