FEATURE: Southisene Brothers Shine at 17U Champs NC

Brothers Ty and Tate Southisene stand out at the 2023 National Team Championships in North Carolina

From the DiMaggio’s to the Diaz’s, brothers have been a staple in the game of baseball since its creation.

Brothers Ty and Tate Southisene, members of the USA Prime National 17U team, are continuing the trend of exceptional brother duo’s in baseball at the 2023 National Team Championships in North Carolina.

A third Southisene brother, Tee, is also a member of USA Prime National 17U and a University of Southern California commit, but was unable to attend this week’s event.

While all three brothers are members of the 17U team, twins Ty and Tee are members of the 2024 graduating class while younger brother Tate is slated to graduate in 2025.

Despite the difference in age, the brothers are accustomed to playing together as they play on the same team at their high school in Henderson, Nevada, and take pride in competing together.

“It's great,” Ty said. “We all come to the same field at the same time in the same car so it's way easier for everybody. You get to see these guys develop, and you get to see your brothers develop. Being the older brother, all you want to do is see your little brother succeed when you know how hard they work. All you want to do is wish them the best and hope they do well.”


Although the brothers love being on the field together, a natural sense of competitiveness has formed among the three Southisene’s over the years.

“I'm always trying to beat him,” Tate said. “I’m always trying to do better than him, be better than him, be faster than him. We work out together and I’m always trying to lift more than him. Everything's a competition between our brothers, trying to make each other better.” 

After the 2022 National Team Championships in North Carolina last year, Ty was able to earn a place on the 2022 18U National Team roster.

The two-way player donned the red, white, and blue as an infielder and right handed pitcher at the 2022 World Baseball Softball Confederation (WBSC) World Cup Americas Qualifier in Mexico where he played in seven games and appeared twice on the mound.

Ty was an integral part of the team’s success, contributing 10 runs and five RBIs while posting a .381 average and 2.10 ERA in Team USA’s gold medal run.

“It was a great experience,” Ty said. “Learning from everyone from different parts of the country and playing for Team USA is a special feeling. It's a different atmosphere and it's a different ‘why.’ Why you want to play baseball and why you want to do certain things. It's bigger than baseball when you play for your country.”

With his older brother finding such success following last year’s edition of the National Team Championships in North Carolina, Tate entered the tournament looking to put himself on the radar of the USA Baseball Task Force and contribute to USA Prime’s success.

The team holds a 2-2 record through three days of competition and will compete in a final consolation game on Friday.

“We're definitely walking into tomorrow’s game trying to win,” Ty said. “We walked into today trying to win, but I think this time we’re trying to go in with a better attitude and more ‘why.’ A bigger chip on our shoulder to show these people that we're the real deal.”

The Southisene brothers will have one final year playing together at Basic Academy (Henderson, Nev.) before Ty and Tee begin their collegiate careers across the country from one another at the University of Tennessee and University of Southern California, respectively.

Tee will be joined by Tate, who is also a USC commit, in one more year, but Ty will be carving his own path at Tennessee.

“It’s definitely going to be hard living across the country from my family, but I was committed to Tennessee first and these guys committed to USC second,” Ty said. “I feel like my heart's at Tennessee and I'm hoping to do good things there.”

Whether they’re playing together or apart, the Southisene brothers' futures in baseball are bright.
