Lithuanian team revamps games for Ball brothers
The Lithuanian team that signed LiAngelo and LaMelo Ball has withdrawn from the Baltic Basketball League and will play in a series of "friendly" games to get the brothers extensive playing time.
Prienu Vytautas now will play in the "Big Baller Brand Challenge" and the team announced it will show each of the games on Facebook, according to ESPN's Jeff Goodman.
"When you come out and they change it just for the Balls, you know it's real," LaVar Ball, the creator of Big Baller Brand, told ESPN.
Prienu Vytautas will continue to play in the Lithuanian domestic league. The Baltic league is considered lower-level than the Lithuanian league, which features squads from Estonia, Latvia and Lithuania.
"This is a great thing for everybody," Ball told ESPN. "I'm excited for the fact they named something after the Big Baller Brand. Brings exposure to our brand and also gives us quality basketball. People back home get to watch it."
The Ball brothers' first game with Prienu Vytautas will take place Tuesday as part of the Big Baller Brand Challenge, and the opponent now will be Zalgiris 2, the younger team of Lithuania's premier program.
LiAngelo, 19, and LaMelo, 16, and their family were slated to accompany the Lithuanian team to its game in Vilnius on Saturday, but LaVar Ball told ESPN that they did not make the trip after the opposing team did not initially allow the cameras from their reality show in the gym.
LaVar Ball previously said the goal was to find a league overseas where both of his younger sons could play on the court together. His oldest son, 20-year-old Lonzo Ball, was the No. 2 pick in the 2017 NBA Draft and is the starting point guard for the Los Angeles Lakers.
