ATLANTIC CITY, New Jersey – The sacrifices Eimantas Stanionis made over the past two months will benefit his unborn daughter someday.

That’s why Stanionis didn’t hesitate to accept a welterweight title unification fight against Jaron “Boots” Ennis that was scheduled for Saturday night, three days after his wife’s due date. Emily Stanionis hadn’t given birth to their first child as of Thursday night.

Her husband still might miss their daughter’s birth because he can’t fly home to Lithuania until Sunday, the day after his career-defining fight with Ennis.

The fact that two of the most significant moments of his life could occur on the same day hasn’t affected Stanionis’ psyche in advance of his 12-round, 147-pound championship clash with Ennis at Boardwalk Hall (DAZN; 8 p.m. ET).

“Honestly, it’s been zero stress,” Stanionis told The Ring after a press conference Thursday at Caesars Atlantic City. “It’s sacrificing a lot. People in the United States, they go to the camp let’s say from New York to Miami. And they say, ‘Oh, I miss my family.’ I go, it’s a 10-hour difference. I sacrifice two months without family, going back and forth.

“That’s a sacrifice. And I miss my family, everybody. My wife, she’s pregnant. I think about it, but I’m not stressing because she supports me, she supports what I’m doing. It’s for us. She says she wants me to be there with her and I want to be there, but it doesn’t work like that.”

The 30-year-old Stanionis spent much of the past two months in Hollywood, California, where he is trained by Marvin Somodio at Freddie Roach’s Wild Card Boxing Club. He is thankful that his resilient wife is in good hands with family in their native country.

“She is mentally strong,” Stanionis said. “Sometimes, I think she’s stronger than me.”

Stanionis (15-0, 9 KOs, 1 NC), a 2016 Olympian, hopes he is mentally and physically stronger than Philadelphia’s Ennis (33-0, 29 KOs, 1 NC) in their fight for Ennis’ IBF, Stanionis’ WBA and the vacant Ring welterweight titles. Ennis is a 6-1 favorite, according to DraftKings, in this battle between The Ring’s No. 1-ranked Ennis and second-rated Stanionis.

Terence Crawford (41-0, 31 KOs) vacated The Ring welterweight crown when the four-division champion moved up to the 154-pound weight class last year.
