KANSAS CITY, Mo. -- Second baseman Neil Walker had two items hanging in his locker in the visitors’ clubhouse at Kauffman Stadium after the New York Mets completed their season-opening series with a 2-0 win against the Kansas City Royals on Tuesday.

One was a Pittsburgh Penguins toiletry bag. The other was the wrestling-style championship belt awarded by David Wright to Walker as the player of the game.

Walker, whose two-run homer in the fourth inning against ex-Met Chris Young accounted for all of the scoring, wasn’t sure he fully deserved the honor, though. After all, Noah Syndergaard fired six scoreless innings in the Mets’ first 2016 victory.

“I’ve heard a lot about it -- the mystique of it that comes along,” said Walker, who was acquired from the Pittsburgh Pirates for Jonathon Niese during the winter meetings in December. “That was a really cool moment to get it today. But I don’t know if I completely deserve it. You saw what Noah did today. I think we’ll split it.”

As for the Penguins bag, the Pittsburgh native said with a laugh: “I was waiting for some questions on that one. Your heart is where your heart is, I guess, when it’s not baseball.”

Walker, of course, succeeded playoff hero Daniel Murphy, who defected to the Washington Nationals for three years, $37.5 million after the Mets acquired Walker and new double-play partner Asdrubal Cabrera.

Asked if he had heard about Murphy’s big debut with the Nationals on Monday at Atlanta (2-for-3 with two walks, a homer and two RBIs, including a game-deciding RBI double in the 10th), Walker initially said: “I’m worried about what’s going on with this team and in this clubhouse. I’m only doing what I can do to help this team.”

Pressed, Walker conceded he was familiar with Murphy’s production.

“Yeah, I knew he hit the home run,” Walker said. “Like I said, it’s not about him. This is about the Mets.”

Manager Terry Collins thought it was “huge” that Walker could contribute during the opening series. Walker went 2-for-8 during the series.

“I think it gives him all of the confidence,” Collins said. “Even though we knew he’s a real good player, the rest of the guys are looking around saying, ‘Hey, we’re in good shape. We’ve got a real good player on our hands.'”

Collins also is pleased with the early returns from his new double-play tandem in the field.

“They’ve been really good up the middle so far,” Collins said. “We’ve turned some double plays that in the past we might not of.”

Said Walker: “I think my play is going to speak for itself. You can never really tell anybody how to think or react. All I can do is go out and play and hope that I’m accepted as a Met.”
