The Japanese team haven't been seen too many times this season, but are trending upwards after their best performance of 2023.
Saitama went up a gear in the knockout stages with thrilling victories over Paris (FRA) and Tubingen (GER) to qualify for the final.
They were unable to crack Raudondvaris Hoptrans, but Saitama can feel well pleased with their efforts and it's a performance to build on.
Sizzling Sucur: The 23-year-old Petar Sucur has impressed in his first season on the 3x3 pro circuit.
And he stole the show for his team in Hongcheon with a lights out shooting display, proving particularly dangerous when he went into attack mode.
Sucur is the latest Serb to dominate the half-court and he's just getting started.
The Final: Raudondvaris Hoptrans 21-Saitama ALPHAS EXE 14
The Lithuanians entered as favorites after beating Saitama on Day One and started quickly with walking bucket Aurelijus Pukelis red hot from the get go.
Saitama needed to hit the scoreboard and turned to Petar Sucur, who attacked the rim for a layup before splashing from downtown to get the Japanese back in the contest.
Saitama had the momentum as they hit the lead at the halfway mark before Raudondvaris took over with deadly duo Pukelis and Marijus Uzupis reeling off seven straight points to turn the game on its head.
The pair were unstoppable with Uzupis nailing a two to clinch Raudondvaris' deserved title.
Pukelis sealed his MVP with a game-high 10 points capped by an insane 10 of 10 shooting from the half-court.
