After scoring 19 runs over their first two games, a hitting eruption that included four home runs, Mets manager Terry Collins allowed himself to fantasize about the possibility of power hitters Lucas Duda and Ike Davis becoming modern day Bash Brothers.

Duda and Davis both belted two-run homers in the Mets’ 8-4 win over the Padres on Wednesday night, so Collins couldn’t help but think of good things to come.

“If those two guys are swinging the bats like they can and driving in runs by hitting the ball in the seats, it’s going to be a tough lineup to get through,” Collins predicted.

Not so fast. Padres starter Eric Stults and five relief pitchers threw a cold tub of ice over the Mets’ red-hot hitters as San Diego claimed a 2-1 victory yesterday afternoon at Citi Field. The only noise from the Mets offense came in the ninth-inning when catcher John Buck smashed a solo home run off closer Huston Street. Otherwise, the Mets were punchless, going 0-for-5 with runners in scoring position and striking out 14 times.

“Our offense didn’t really show up,” Davis said. “At least we had a chance. It wasn’t a blowout.”

That’s why it should sting all the more. The Mets (2-1) are the kind of team where games like this matter, even in April, even in the third game of the season. They need every win they can get.

As much as the first two games — wins of 11-2 and 8-4 — raised expectations about what the Mets could be, yesterday’s loss was a reminder of what they are: a team that can pound the ball hard or strike out a lot. Duda whiffed in all three of his at-bats as did David Wright. Davis was 0-for-3 with two strikeouts.

“We got a little anxious,” Davis said. “Instead of staying back on pitches, we tried to hit that three-run homer instead of hitting a nice easy base hit up the middle.”
