Ike Davis got just enough of the pitch.

Enough to make him Sunday's hero.

And enough to prevent him from looking like a fool, as he described it.

The first baseman's walk-off homer in Sunday's 2-1 win over the Astros barely cleared the wall -- and the glove of outfielder Ben Francisco. Davis hadn't busted it out of the box as he felt that the ball had cleared the ball comfortably. It was his second homer on a day he provided all the Mets' runs.

"I thought I hit it a little bit better than I did," Davis said. "Outfielder kind of deked me a little bit and scared me because I would looked like a fool because I didn't run out of the box and get on second base. That's the only thing that came through my mind."

The Mets struggled to hit all weekend, and they were again helpless on Sunday against Houston. They had just four hits, two from Davis. The first baseman pulled both balls into the right-field seats to give him 24 homers.

In the fourth, he belted a no-doubt shot to give the team a 1-0 lead. It appeared that was going to hold up until the Mets blew the lead. In the ninth, batting second, Davis helped the Mets avoid what would have been an embarrassing series loss by clearing the wall in right. He now has 70 RBIs on the year.

"We needed it bad," Mets manager Terry Collins said. "You look up in the ninth and a guy's really pitching good, we had one run on the board again and three hits and you're just thinking, 'Hey, somebody's got to get this going. Fortunately I think that's what Ike did today. I think he got it going."

While Davis, at .223, has struggled to hit for average all year, he's notched a career-high in home runs and is just one RBI short of his career-best. He came into the year wanting to hit 20, which he had never done, and admitted he didn't foresee himself being within six homers of reaching 30.

"I was so bad for so long and hitting .220 would have seemed pretty outrageous at that time but it started turning around a couple months ago," Davis said. "Hopefully I can continue to get better and grind out at-bats and we'll see what happens."
