NEW YORK -- Cliff Floyd stood and watched another home run sail deep into the upper deck at Yankee Stadium.
Everyone is teeing off against the Bronx Bombers lately, including their crosstown rivals.
"You can't come in here and expect these guys to make mistakes. But if they do, we have to capitalize, and we have," Floyd said.
Tom Glavine pitched six effective innings, sending the bumbling Yankees to their fourth straight loss and leaving both Big Apple teams at 37-37.
"I feel embarrassed. We take a lot of pride in what we do and it's just not working out," said catcher Jorge Posada, adding that he's not sleeping well lately.
"We are doing a lot of things that look bad out there," he said. "I've never seen it like this. You see signs of good things where we're playing good and then you see really, really bad signs. It's really a roller coaster."
"It would be awesome," Floyd said.
They've already won a series there for the first time -- the Mets lost all seven previous interleague series in the Bronx.
Bernie Williams had another embarrassing lapse in center field, and rookie Sean Henn was roughed up again for the Yankees, who have dropped five of six to the Devil Rays and Mets -- both last-place teams -- after going 6-0 to start their 13-game homestand.
"I think we're just trying to do too much," manager Joe Torre said. "We don't feel very good about ourselves right now, and that goes from the first player to the 25th player and the staff."
With chants of "Let's Go Mets!" filling a sold-out Yankee Stadium, the Bronx Bombers fell 6½ games behind first-place Boston in the AL East. They are 0-26 when scoring three runs or fewer.
"The Yankees are the Yankees and they have a ton of expectations. For them to be .500 this late in the season I'm sure is disappointing to a lot of people," Glavine said. "I would be shocked if they don't turn it around."
Glavine (5-7) won for the first time in four starts, working out of trouble on a humid, 90-degree afternoon. He scattered seven hits for his 267th win, passing Bob Feller and Eppa Rixey for sole possession of 32nd on the career list. Next up is Hall of Famer Jim Palmer with 268.
"There's no better place to pitch than here, and there's no better test than this lineup, regardless of what they may or may not be doing," Glavine said.
Tagged twice by Tampa Bay, Henn (0-3) didn't fare much better in his third major-league start. He allowed six runs and seven hits -- including three homers -- in 4 1/3 innings.
The Yankees have allowed 12 home runs in their last five games.
Williams, struggling in center the past few days with physical and mental gaffes, hesitated after putting away Carlos Beltran's routine fly in the first inning, apparently thinking it was the third out. That allowed Mike Cameron to tag up and move to second.
"I was just out of position trying to catch that ball in the middle of the sun," Williams said. "I caught it and then Ruben (Sierra) told me that he was tagging and it was just too late.
"There's no room for mental mistakes."
Floyd then drove a 3-2 pitch into the right-field upper deck for a 2-0 lead. He said he didn't think he'd ever hit a ball that far before.
Wright connected leading off the second, his 11th.
Henn backed Floyd off with a high-and-tight fastball in the third, but Floyd wasn't fazed at all.
Two innings later, he followed Beltran's RBI double with another two-run shot, making it 6-2. It was Floyd's 20th homer of the season and fourth in five games. He also walked twice and scored three times.
"I don't know what to say. Hitting after him, I'm starting to get an inferiority complex," Mike Piazza said. "He's just a monster right now."
Cano homered in the ninth off Danny Graves.
"They're still champions in my mind. They'll be fine," said first-year Mets manager Willie Randolph, a longtime coach with the Yankees. "In a lot of ways in my heart, they're still my boys."
- Mets 1B Doug Mientkiewicz left in the fifth with a tight right hamstring and is day to day. But he said there's "no chance" he'll play Sunday night.
- Floyd has 12 career multihomer games, three this season.
