TAMPA — Beginning on Saturday many of the Yankees will get their first taste of working with a pitch clock involved.

MLB is using a 20-second clock in exhibition games with an eye on implementing the rule in the regular season contests via an agreement with the Players Association or commissioner Rob Manfred doing it himself.

Most of the Yankees pitchers asked about working with a clock — that is meant to quicken the pace of the game — didn’t think it would have that big of an effect.

The lone dissenter was veteran left-hander J.A. Happ.

“I don’t like it, I don’t think it is necessary,’’ Happ said Friday at George M. Steinbrenner Field on the eve of the Yankees’ opening the exhibition season with a game against the Red Sox in Fort Myers on Saturday in which a clock will be used.

“I don’t think the numbers prove the game needs it and it doesn’t feel right.’’

As for the possibility of using the clock when real games begin, Happ didn’t know for sure but said, “I hope not.’’

According to FanGraphs, Justin Verlander was the slowest between pitches among those who qualified with a 27-second clocking. The other four slowest were David Price (26.9), Aaron Nola (26.6), Jake Odorrizi (26.1) and Zack Godley (25.6).

Yankees ace Luis Severino needed 22 seconds between pitches, while Happ was at 22.3.

Aroldis Chapman was at 29, Masahiro Tanaka at 27, Zack Britton at 26.4, Tommy Kahnle at 26.3, Jonathan Loaisiga at 26.3 and Jonathan Holder at 25.8. None of them, though, worked enough innings to qualify among statistical leaders.

The clock will begin after the first pitch of an at-bat, once the pitcher is in the dirt circle of the mound with the ball and the catcher is in position. A pick-off throw, wild pitch or passed ball would cause the timer to be reset to 20 seconds, starting again once everyone is in position. If the pitcher fakes a pick-off throw or steps off the rubber with runners on base, the clock would reset immediately.

“It will be interesting to see. As long as I don’t pay attention I don’t think it will be a distraction and I will be fine,’’ Dellin Betances said. “I don’t know if it will quicken the game.’’

Aaron Judge has experience with the clock, which was introduced in the minor leagues in 2015.

“I dealt with it in the minor leagues. To me I didn’t notice it,’’ Judge said.

According to CC Sabathia the clock won’t deliver drastic change.

“I don’t think so, most guys work quick. Some relievers are slow. I don’t think it will be a huge difference,’’ Sabathia said.

Adam Ottavino said he will attempt to push it out of his mind.

“Try not to think about it,’’ the reliever said. “See how it works and adjust accordingly.’’

Austin Romine doesn’t believe the clock will have an impact.

“I don’t think it will matter,’’ the catcher said of the rule that also forces hitters not to loiter at the plate. “It’s there, abide by it and move on.’’
