ST. LOUIS (AP) -- Mike Pelfrey could get used to this kind of run support.
The Mets beat the Yankees 15-6 in Pelfrey's last start, he won a 9-6 game last month, and had a 3-0 lead against the Cardinals before throwing one pitch.
"If you can't win with that kind of run support, you know you're going to have problems," Pelfrey said. "It takes all the pressure off, and you don't feel like you have to be so perfect."
Carlos Delgado had a two-run homer and three RBIs as the Mets pounded rookie Mitchell Boggs, rebounding from a one-run loss to earn a split in the four-game series entering a four-game series at NL East-leading Philadelphia starting Friday.
"We just kept the line moving, and that's what it takes for this offense to be successful," New York third baseman David Wright said. "It seemed like everybody chipped in. You get a big walk here, a big two-out RBI there and we just kept rolling."
Damion Easley, the stand-in starter at second base with Luis Castillo (quadriceps) on the 15-day disabled list, had two hits and an RBI for the Mets and finished 7-for-13 in the series. The Mets had 39 hits and 25 runs the last three games of the series after losing the opener 7-1, and have double-digit hit totals four of the last five games.
Wright was removed in the middle of the sixth as a precaution after interim manager Jerry Manuel said he appeared to tweak his groin running the bases. But Wright said he was fine and wouldn't miss any time.
Boggs (3-1) surrendered 11 runs, 10 hits, six walks and two wild pitches in six innings, taking a massive hit to his ERA with manager Tony La Russa intent on saving his bullpen for a three-game weekend series against Central-leading Chicago.
No relievers even warmed up while Boggs faced 10 batters in the third and the Mets went ahead 9-0. La Russa was booed by the sellout crowd of 43,098 after making a brief visit to the mound, presumably to tell Boggs there would be no help.
"I would rather save [him] the beating when it's not his night," La Russa said. "I was concerned about that, but I was much more concerned about the effect on the rest of our pitching staff trying to finish that game with three more to play before an off day."
The Cardinals used five relievers in an 8-7 victory on Wednesday and a sixth, Brad Thompson, worked four innings on Tuesday. The 24-year-old Boggs, who entered with a 4.37 ERA and exited at 6.59, also committed a fielding error that allowed an unearned run to score in a three-run first.
"I'll tell you, I'm disappointed," Boggs said. "I let it get away from us early. I've got to get better, there's no sugarcoating it."
Aaron Miles extended his hitting streak to a career-best 15 games, also the Cardinals' high this season. Yadier Molina and Adam Kennedy each had two hits in a game delayed for 26 minutes at the start by rain.
Pelfrey (6-6) allowed a run and six hits in seven innings in his first career appearance against St. Louis, winning his fourth straight on the road, and the Mets have won six of his last seven starts. He had been 2-for-57 (.035) for his career before his RBI single in the third.
"I'm definitely having a lucky night if that happens," Pelfrey said. "I was just happy it dropped because I thought it broke my bat. I don't even remember seeing the pitch. I probably closed my eyes."
Wright made the first and last outs in the third, which included an RBI double by Endy Chavez. Reyes leads the majors with 10 triples, two ahead of the field after a drive over the head of center fielder Rick Ankiel, and his 62 career triples tied Mookie Wilson's franchise record.
Delgado, who was 5-for-12 in the series with four RBIs, made it 11-0 in the sixth with his 15th homer.
Mets bench player Fernando Tatis had 34 homers and 107 RBIs in 1999 with the Cardinals, and this was his first trip back to St. Louis. "It meant a lot to me, this place," Tatis said. ... Miles is batting .400 (26-for-65) during his hitting streak, which tops Albert Pujols' 14-gamer from April 30-May 15 as the team's longest this year. ... Molina is batting .351 (13-for-37) during a 10-game hitting streak.
