Spencer Jones’ girlfriend, Ava O’Connor, shared a sweet message responding to the 6-foot-7 outfielder getting called up by the Yankees after Jasson Domínguez was injured during Thursday’s game.

“Let’s go baby! The most deserving incredible man. I love you!” O’Connor wrote on her Instagram Story, including the MLB breaking news post and a fire flame emoji and a blue heart.

The Post’s Jon Heyman was the first to report the news Thursday.

Jones, the Yankees’ No. 6 prospect on MLB Pipeline, has 11 homers and a Triple-A leading 41 RBIs to start the season.

The 24-year-old slugger will get his chance at the majors after he struggled with strikeouts in the minors this season, tallying 46 through his first 33 games with Triple-A Scranton/Wilkes-Barre.

Jones was called up after Domínguez crashed into the outfield wall while making a catch during the first inning of the 9-2 win over the Texas Rangers on Thursday.

Domínguez, who was filling in for an injured Giancarlo Stanton, was emotional as he left the game on a cart.

An MRI revealed a sprain in the AC joint in his left shoulder, sending him to the injured list.

Yankees manager Aaron Boone cited consistent at-bats recently when asked about Jones after Thursday’s game.

“Feel like the last three, four weeks, been having a lot of consistent at-bats,” Boone said. “The power’s been there. Less swing and miss. … The signs have been encouraging.”

Jones will suit up Friday for the start of the Yankees’ three-game series against the Brewers in Milwaukee.
