John Buck will take the increased expectations that are sure to come if he can continue anywhere near this pace.

The Mets catcher just concluded one of the great debut months in franchise history and doesn’t believe it was a fluke. So if you now expect the 32-year-old Buck to deliver a big hit on a regular basis, go ahead, he says.

“It’s more positive energy in my favor,” said Buck, who will bring his nine home runs and 27 RBIs to Turner Field tonight against the Braves.

His latest important contribution came Wednesday, when Buck delivered a two-run double in the seventh inning as part of a 3-for-5 performance in the Mets’ 7-6 victory over the Marlins that snapped a six-game losing streak.

The Mets never saw this coming. Buck had been an All-Star with the Blue Jays in 2010, but after two mediocre seasons with the Marlins, he was hardly considered a significant component in the December deal that sent R.A Dickey to Toronto and returned an elite catching prospect in Travis d’Arnaud.

Buck’s nine homers last month tied a Mets record for April, and he was the NL leader in RBIs as yesterday’s play began. The Mets are 11-15, but realize without Buck’s great start, the season might already be completely flushed.

“I can’t begin to tell you where we would be if he didn’t get off to the start he got off to,” manager Terry Collins said. “We could be five-and-whatever.”

Buck hit .192 with 12 homers and 41 RBIs in 343 at-bats for the Marlins last season and was traded as part of the blockbuster deal that sent Jose Reyes to Toronto. Almost immediately, he was informed by Blue Jays general manager Alex Anthopoulos there was a good chance he wouldn’t be staying, as the team would seek to trade either him or J.P. Arencibia.

“A lot of players like Alex Anthopoulos so much because he is so upfront, which helped me realize right away going into the offseason I’ll be playing every day, whether it’s in Toronto or someplace else,” Buck said.
