NEW YORK -- One night after blowing a lead, the Milwaukee Brewers handled the late innings perfectly.
Bill Hall homered in the seventh to end Martinez's most dominant stretch of the game and Carlos Lee added a tying shot in the eighth for the Brewers, who couldn't hold a four-run lead in Tuesday's 11-inning loss but rallied against the Mets' bullpen Wednesday.
With two outs in the ninth, Wes Helms reached on an infield single against Mets closer Braden Looper (4-5) and Brady Clark singled. Looper walked Rickie Weeks, loading the bases, before Overbay singled up the middle for a 6-4 lead.
"Those at-bats in the ninth inning when we had two outs were great," Overbay said. "Perfect hopper in the little hole right there and he was safe at first with Wes, and Brady's been doing that all year, and Rickie had that great at-bat. You don't see three pretty good at-bats in a row."
Rick Helling (1-0) worked the eighth for his first major league win since Sept. 20, 2003, for Florida against Atlanta. Derrick Turnbow, who gave up Mike Cameron's tying homer in the ninth Tuesday, bounced back to retire Carlos Beltran with runners at second and third for his 22nd save in 25 chances.
"I was glad I got the opportunity," Turnbow said. "Any time you don't pitch well you want to get back out there and compete and hopefully get the job done."
Cliff Floyd and Mike Piazza homered for the Mets, who lost for the second time in nine home games. David Wright had a two-run single but committed an error to start the ninth.
Martinez settled down after a rocky start and left with a 4-3 lead after allowing eight hits in seven innings. He struck out eight, raising his NL-leading total to 163, but Roberto Hernandez gave up Lee's 27th homer with one out in the eighth.
Hernandez and Looper each pitched two innings Tuesday, but Mets manager Willie Randolph didn't think that was the reason for their ineffectiveness Wednesday.
"They were ready to pitch. They told me before the game they were ready," Randolph said. "That's the life of a reliever. It was a big game for us, they were ready to go."
The Brewers went up 2-0 in the second. Lee led off with a double, and Damian Miller lined a two-out RBI double to right-center. J.J. Hardy singled to center on the next pitch to score Miller.
The Mets answered in the bottom half when Floyd led off with his 25th homer, a drive estimated at 420 feet that appeared to bounce off the top of the home run apple in center field.
Piazza fouled off three 3-2 pitches in the fourth before sending a drive over the left-field bleachers, tying it at 2-all and earning another curtain call -- as he has done after each of his recent homers at Shea Stadium.
Martinez kept the Brewers in check from there, allowing just one hit and striking out six between the third and sixth. He fanned four straight in the fifth and sixth, including Overbay, Lee, and Geoff Jenkins -- the middle of Milwaukee's order.
"I found my groove," he said. "I was able to get my breaking ball over. Once I got in like the third inning, I was able to make pitches pretty consistently."
Wright's two-run single in the fifth gave the Mets a 4-2 lead, but the Brewers got a big run in the seventh on Hall's 14th homer leading off the inning. Milwaukee got two more hits in the inning before Martinez retired Weeks with two on.
"Any time you can get within one, that's huge," Brewers manager Ned Yost said. "And Billy Hall stepped up and did that for us. We still had time left."
Piazza's homer was his 391st, breaking a tie with Graig Nettles for 45th place on the career list. ... Beltran was booed after his first two at-bats, despite hitting the ball hard for outs both times. He was booed throughout his return to Houston last weekend, then again while going 0-for-6 Tuesday. "I can't control the fans, the only thing I can control is how I play the game," Beltran said before the game. "When it's going to change, I don't know. But I feel like it has to." ... The Mets lost an NL-record 146 consecutive times when trailing by at least four runs before rallying to beat Milwaukee 9-8 in 11 innings Tuesday night, according to the Elias Sports Bureau. New York hadn't overcome a four-run deficit since July 28, 2002, against Cincinnati. ... The Brewers, 15th in the NL in fielding percentage, had played a season-high six straight errorless games before Hardy's error at SS in the fifth. ... Mets SS Jose Reyes extended his hitting streak to 16 games, the longest current run in the majors.
