When Kevin Plawecki went on the disabled list with a broken hand April 13, he was hitting all of .150. When he returned May 28, he immediately went out and pretty much tried to make up for lost time. He was better. But not by much. The Mets catcher hit .193 in his next 18 games.

But since mid-June, Plawecki has turned it on. In his past 14 games with an at-bat, entering the start of the current Subway Series with the Yankees on Friday, Plawecki has hit .302. The reason? Approach, not health. He is using the whole field.

“Definitely approach-wise,” Plawecki said. “I just focused on keeping my approach to right field.

“Coming back from my injury, it took me a little bit longer to find that contact point in my swing. A lot of balls I should be driving, I was catching out front rather than catching them deep and being able to drive balls instead of rolling over and hitting ground balls. And I’ve just been trying to swing at strikes.”

That helps, too. It is a universally accepted practice among hitters to lay off pitches that bounce, sail over one’s head or are located in adjacent zip codes.

“Really, that’s about it. Just keeping my approach to right center and just reacting,” said Plawecki, who did not start Friday.

No one is arguing with the results. In that 14-game stretch, including 11 starts, Plawecki went 13-for-42 with two homers, five doubles, a triple and eight RBIs.

“Our hitting coaches have worked really hard with him on making sure he stays inside the ball and is driving the ball to right field in his early work,” manager Mickey Callaway said. “He’s able to cover more pitches that way. One of the things we valued in Kevin coming into the year was his ability to lay off of tough sliders and breaking balls that are strikes, the ball on the outside corner.

“He’s done a really good job and has really worked diligently to stay inside the ball and drive the ball to right-center. That allows him to cover mistake breaking balls to the pull-side [and] to drive the ball to right-center.”

And with some success, Plawecki finds himself in a better mental place, too.

“In the past, being young in the league and trying to establish yourself and trying to prove to people you know what you’re capable of, it’s frustrating,” Plawecki said. “It goes back to maybe putting too much pressure on yourself and trying to make things happen rather than trying to take it day-by-day and flushing what happened yesterday. … It goes back to the second half last year. It was mentally how I kind of flipped the switch.

“Finally comfortable. It’s part of the process, part of the learning curve part of learning to play in the major leagues.”
