PORT ST. LUCIE — Travis d’Arnaud’s energized bat is among the Mets’ positive developments this spring, but results are lacking in another facet of his attempted revival.

The Mets are hardly panicking, based on the limited sample size and the fact d’Arnaud is only half of the equation when opponents decide to run. And yet there is this statistic: d’Arnaud is 0-for-5 attempting to throw out base stealers this Grapefruit League season.

The statistic doesn’t matter to d’Arnaud, who says his work with new catching instructor Glenn Sherlock has been fruitful, bolstering his confidence that a breakthrough is evident.

“I’m firing to second, firing to third, without really thinking right now,” d’Arnaud said Sunday. “I feel like I just over-thought things last year with mechanical stuff. I’m usually not that guy. I usually stay free and easy and loose, and it just happens.”

Manager Terry Collins is looking more at the process than d’Arnaud’s early results. After all, d’Arnaud’s backup, Rene Rivera — who is well-regarded for his throwing — is 0-for-6 against base stealers this spring.

“[D’Arnaud] has got much better action, much better footwork, the ball is coming out of his hand better and he’s not hesitating on anything,” Collins said. “I’ve seen a lot of improvement.

“We have just got to continue to work at the stuff that we came into camp to do, so it becomes second nature to him and hopefully he keeps swinging the bat the way he has been.”

D’Arnaud threw out only 17-of-61 (27.9 percent) of base stealers last season, prompting the Mets to hire the veteran catching instructor in the offseason as a mentor. The Mets were without a catching instructor in 2016, after bench coach Bob Geren left to join the Dodgers.

A year earlier, under Geren’s tutelage, d’Arnaud threw out 14-of-29 (48.2 percent) base stealers.

“The biggest thing I’ve taken away from Glenn this spring is just stay consistent with all my work, have a purpose behind the work, just don’t go through the motions,” d’Arnaud said. “Also, have fun. It’s still a game. You can’t overthink it or anything. Just trust that all the work you do before the game is going to translate.”

Offensively, d’Arnaud has been a bright spot for the Mets this spring — he is 10-for-26 (.385) with two homers and four RBIs. Last season he hit only .247 with four homers and 15 RBIs in 75 games. D’Arnaud said the decision to condense his swing, lowering his hands and eliminating the “wrap” around his head has helped.

“The wrap was making my swing a little longer so I would almost have to cheat to hit pitches versus just reacting to pitches,” d’Arnaud said. “I’m quicker to the ball.”

D’Arnaud will have another mentor in camp for the next two days, when Hall of Famer Mike Piazza visits to serve as a guest instructor. For d’Arnaud it will be another opportunity to receive pointers from a player he idolized in his youth.

The two became friendly in 2014, when Piazza visited camp and worked with d’Arnaud. Before Piazza left, he gave d’Arnaud his cell phone number with instructions to call if he had any questions. D’Arnaud, who grew up in Southern California, admitted it’s been “awhile” since he’s spoken with his boyhood hero, whose illustrious career began with the Dodgers.

But d’Arnaud says he will be listening this week to any wisdom Piazza might want to impart.

“It’s never just an ordinary conversation,” d’Arnaud said. “I am a 10-year-old kid watching a Dodgers player.”
