The pairing was a nod to the future, an appetizer of seasons to come. Matt Harvey, 23-year-old ace-in-waiting, threw 39 pitches to Travis d’Arnaud, 24-year-old heir to The Kid.

The results could have used a coat of wax. Harvey surrendered a home run to former Mets outfielder Fernando Martinez; d’Arnaud went 0-for-3 with two strikeouts.

But the thought of these two twinned together – not just for a spring training game in central Florida, but for a string of summers in Queens – was enough to get both men and their manager beaming about the bright lights down the road.

"I thought they both did a good job," manager Terry Collins said after the team’s 7-all tie with the Houston Astros at Osceola County Stadium. "I thought Travis did a nice job of handling, calling the game. And I thought his receiving was very good. Matt threw good. He made some good pitches."

With 10 major league starts looped to his belt, Harvey did not have to battle as many heart palpitations. He allowed one run over two innings. Three times he set down an opposing hitter on strikes.

One National League talent evaluator who scouted the Mets’ prized arms on back-to-back days – Zack Wheeler on Saturday in Port St. Lucie, Harvey on Sunday in Kissimmee – said Harvey is further along right now.

"[But] not much," he said. "They’re pretty close."

Harvey’s fastball bounced between 94 and 98 mph, according to that same evaluator. He threw 39 pitches, 25 for strikes.

"The arm and the body [are] in shape," Harvey said. "It’s just a matter of the location. I’m not quite there. I made a lot of good pitches, but I also made some that missed the plate a little too much."
