It’s easy for Yankee players to understand what Giancarlo Stanton will bring to a lineup that had plenty of muscle a year ago.

Yet, what Greg Bird also took away from the news that the Yankees and Marlins have agreed in principle to a deal that brings the reigning NL MVP to The Bronx is the message behind the move.

“It’s a great lineup with Gary [Sanchez], [Aaron] Judge and Stanton but the coolest thing about it is that we are in it to win,’’ the Yankees’ first baseman told The Post via phone on Saturday. “We are firmly committed to winning.’’

Adding Stanton, who led the majors in homers (59) and RBIs (132) last year, certainly helps the Yankees’ chances of winning the AL East for the first time since 2012 and getting to the World Series for the first time since winning it in 2009.

In addition to exciting Bird, it’s likely the Yankees’ fan base feels the same way that Kentucky basketball coach and Yankee fan John Calipari feels about the deal that sent second baseman Starlin Castro and two prospects to the Marlins.

Calipari met with GM Brian Cashman and manager Aaron Boone after the Wildcats beat Monmouth on Saturday at Madison Square Garden.

“We talked about Stanton. We’re going to get that one done,’’ Calipari said.

If Stanton passes a physical the deal could be announced Sunday or Monday.

“I am excited, we are all in,’’ said Bird. “There is a lot of power in that lineup. Getting Giancarlo is huge.’’

The Yankees are expecting power from Bird, who was limited to 48 games last season due to a foot problem that required surgery. He hit .253 (22-for-87) with eight homers, 25 RBIs and a .891 OPS in 29 games from Aug. 26 to Oct. 1. In 13 postseason games Bird hit .244 (10-for-41) with three homers, six RBIs and a .938 OPS.

Former manager Joe Girardi batted Bird third on Opening Day last season. Where Boone hits Bird is yet to be determined, but the first-year manager isn’t likely to bat Judge, Stanton and Sanchez back-to-back-to-back. Boone could break up the right-handed muscle with Bird which would likely result in the left-handed hitting Bird getting pitches to drive.

Bird talked to his new boss after Boone was named the manager and came away impressed.

“Last week, he was awesome,’’ Bird said of the conversation with Boone. “I am looking forward to getting back. I was talking to Judge last week and we are all excited to get back. It’s a good time to be a Yankee.’’
