john buckSeveral times this season John Buck’s fast start fueled speculation that with Travis d’Arnaud’s promotion the Mets might deal him at the trade deadline.

After all, who doesn’t want a hot-hitting catcher who calls a crisp game behind the plate? Most every team would and that includes the Mets, who, along with Buck exceeded early expectations.

It’s not as if Buck has gone from trade bait to indispensable, but he isn’t going anywhere any time soon. And, that has more to do than with d’Arnaud’s broken foot that will keep him out for two months. Buck is simply the Mets’ best offensive weapon and has been solid behind the plate, drawing raves fromMatt Harvey and Jon Niese.However, manager Terry Collins said it best: “John Buck seems to be in the middle of everything that’s good right now.’’

Buck homered in the Mets’ 2-0 victory over Washington Sunday, a comprehensive display of the fastest start of his career. There was the homer, giving him seven and a league-high 22 RBI, but also his defense and the game he called for Dillon Gee.

The Mets’ pride is their young pitchers, and Buck could be the same steading influence Jerry Grote once was to Tom SeaverJerry Koosman and Jon Matlack.

Harvey has been the darling at 4-0 and a sub-1.00 ERA, swears by Buck. There’s no way the Mets break up that duo.

Harvey said he’s shaken off Buck maybe five or six times this year ins describing the same instinctual chemistry a quarterback would have with his best receiver.

“He already knows what’s coming,’’ Harvey said. “It’s really fun every time I take the mound and see him back there. It’s just positive energy. It’s more fuel.’’

It’s not luck or coincidence that has Buck putting down the correct fingers. It’s the culmination of hard work spent in the first nine years of his career. He keeps copious notes on his pitchers and opposing hitters, and they complement the game plan drawn up by pitching coach Dan Warthen.

On the day of the game Buck meets early with Warthen and the pitcher to go over the scouting reports and film. Later, he’ll meet with the pitcher privately. However, he talks to all the pitchers throughout the week, not just on the days they start. The communication is constantly flowing.

Harvey said Buck’s preparation is inspirational to the point where he’ll incorporate what he’s learned throughout his career.

“He knows what the hitters are going to do,’’ said Harvey. “The studying that he does and the video that he watches and the plan that he comes up with for each individual pitcher, it’s something that I’m learning still. And it’s awesome.’’

Buck and d’Arnaud’s lockers were side-by-side in spring training, and it wasn’t by accident, either.

“I like to pick his brain,’’ d’Arnaud said this spring. “He’s very easy to talk with and I’ve learned a lot from being around him.’’

Buck said in spring training he understood he was brought here to help d’Arnaud and that attitude hasn’t changed despite the latter’s injury. It’s not as if when he heard the news he moved out of his apartment and bought a house.

“My stance is still the same,’’ Buck said. “I truly feel if I do good, then he does good. I’ve been around too much to take positive thoughts out of something bad happening to someone else. … Until someone tells me otherwise, I’ll just keep going about my business.’’

Nobody will be telling Buck otherwise any time soon.

As for trading him, in an exclusive interview with Metsmerized Online, Sandy Alderson said very emphatically, “No. No, we won’t. We will not trade John Buck.”
