Shai Gilgeous-Alexander And GF Welcome First Child Together, Playoff Baby!

Shai Gilgeous-Alexander will have a bit of extra motivation through the rest of the playoffs -- the Oklahoma City Thunder star is a new dad!!

The MVP candidate and his longtime girlfriend, former college soccer player Hailey Summer, revealed they were expecting last December ... and on Tuesday, SGA announced to his 3.2 million fans on Instagram their son has arrived.

"Ares Alexander 🤍," SGA said in the caption.

Ares was born on April 25, 2024 ... which was right in the middle of the Thunder's first-round series against the New Orleans Pelicans.

Luckily, SGA was off that day ... as the Thunder were fresh off a Game 2 win the night prior.

SGA's fans think this will be like a superpower for the Canadian baller ... with many flooding the comment section to give their two cents on the impact the family milestone might have on his game for the rest of the postseason.

"Shai is about to get a fatherhood attribute boost," one follower said.

Shai averaged 30.1 points and 6.2 assists per game this season ... so it would be great news for OKC fans, who are celebrating their first playoff series win since the 2015-16 season.

The Thunder are now waiting for the Clippers and Mavericks series to end ... and the winner will meet them in the conference semifinals.
