Nagasaki Delivers Game-Winning Blow: How the Underdog Stunned Okinawa in B.League Championship History
YOKOHAMA, Japan — In a play that will be studied in basketball textbooks for years, Nagasaki’s Keita Baba sank a clutch three-pointer with 12 seconds remaining to send the crowd at Yokohama Arena into a frenzy and hand his team a 1-0 series lead in the B.League Championship. The victory marked the first time in league history that a team making its first-ever Championship Series appearance has taken the opening game against Okinawa’s five-season playoff powerhouse.
The Underdog’s Path to the Final
Nagasaki’s journey to this moment began with a statement victory in their semifinal clash against Chiba Jets, where they outlasted the Eastern Conference’s second seed 102-93 in a game that saw them overcome a 16-point deficit in the third quarter. The team’s resilience was on full display as they forced five turnovers in the final two minutes to seal their spot in the finals.
For Okinawa, the path was equally grueling. Their 90-74 victory over Nagoya Diamond Dolphins in the semifinal was their 11th straight playoff win, extending their streak of consecutive postseason victories to an unprecedented level in B.League history.
The Turning Point: Nagasaki’s Late Charge
With the series tied at 1-1 heading into Game 2, Nagasaki’s strategy centered on exploiting Okinawa’s defensive vulnerabilities in transition. The pivotal moment came when Okinawa’s starting center, the league’s Defensive Player of the Year, fouled out with 3:45 remaining, forcing the team into a zone defense they hadn’t practiced in weeks.
Key Stat: Nagasaki shot 12-of-18 from three-point range in the fourth quarter, including 6-of-10 in the final 5 minutes — a volume and efficiency that shocked Okinawa’s coaching staff.
The game’s most memorable moment came when Nagasaki’s sixth man, Yuto Tanaka, hit a step-back three over Okinawa’s starting point guard with 1:10 remaining to give his team a 98-96 lead. While Okinawa fought back, Baba’s game-winning three with 12 seconds left sealed Nagasaki’s historic victory.
What So for Japanese Basketball
Nagasaki’s victory represents more than just a championship upset—it signals a shifting power dynamic in Japan’s professional basketball landscape. For years, Okinawa has been the league’s dominant force, winning three of the past five championships. But Nagasaki’s run has proven that the B.League’s expansion into new markets is creating genuine competition.
League Perspective: “This is exactly what we hoped for when we expanded the league,” said B.League Commissioner Hiroshi Tanaka in a post-game interview. “We want to see teams from different regions competing at the highest level and Nagasaki has shown that’s absolutely possible.”
The victory also puts a spotlight on Nagasaki’s coaching staff, who entered the season with a record of 22-34. Head coach Takeshi Saito implemented a small-ball lineup in the playoffs that caught opponents off guard, with his team averaging 110.3 possessions per game—12 more than their regular-season average.
Player Spotlight: The Heroes of Nagasaki’s Run
While Baba’s game-winning shot stole headlines, it was Nagasaki’s role players who made the difference. Here’s how the key contributors performed in the Championship Series:

- Keita Baba (G): 24.5 PPG in playoffs, including 8-of-12 from three-point range. His ability to create his own shot in the final minutes has been the x-factor in close games.
- Yuto Tanaka (F): 14.0 RPG and 3.5 SPG in playoffs. His defensive versatility has been crucial against Okinawa’s elite guards.
- Ryohei Fujimoto (C): 18.0 PPG and 8.0 BPG. His shot-blocking and rebounding have anchored Nagasaki’s defense.
Okinawa’s loss wasn’t for lack of effort. Their starting five averaged 22.4 points per game in the regular season, but struggled to contain Nagasaki’s quick transition offense, which averaged 1.25 points per possession in the final quarter of games.
Looking Ahead: Game 2 Preview
The series shifts back to Okinawa’s home court for Game 2, where the home crowd at Okinawa Arena will be a factor. Nagasaki will need to:
- Contain Okinawa’s elite big man, who averages 22.1 points and 10.3 rebounds in playoff games.
- Limit second-chance points, as Okinawa averages 18.2 points off defensive rebounds.
- Maintain their three-point shooting efficiency (42.1% in the series so far).
Schedule Note: Game 2 will be played on May 26 at 7:00 PM JST (UTC+9) at Okinawa Arena. The winner will advance to the Championship Finals, with the series winner being crowned the B.League champion.
Historical Context: How This Changes B.League Playoffs
Nagasaki’s victory marks the first time in B.League history that:
- A team making its first Championship Series appearance has won Game 1.
- A team with a losing regular-season record (Nagasaki’s 22-34) has reached the finals.
- A team from Kyushu has won a playoff series against a team from Okinawa.
This upset could have ripple effects throughout the league, potentially encouraging other expansion teams to invest more heavily in player development and coaching staffs.
