A dominant second quarter and a composed closing stretch gave the Alphas a double-digit win that will be remembered as one of their most balanced offensive nights of the campaign, with five players finishing in double figures and the bench contributing heavily.

How the Game Unfolded

The opening quarter was a scrappy, energetic affair. Iwate's guards attacked the rim early and drew contact, while Koshigaya answered with patient half-court execution and a pair of early three-pointers from the wings. Neither team led by more than five points across the first ten minutes, and the Alphas went into the first break with a slender 22-20 advantage.

The second quarter is where the match was effectively decided. Koshigaya opened with a 12-2 run built on transition baskets and offensive rebounds, forcing Iwate into a timeout before the midway point of the period. The Big Bulls struggled to contain dribble penetration, and the Alphas punished every late close-out with an extra pass and an open corner three. By the time the halftime buzzer sounded, the visitors had stretched the margin to ten at 48-38.

Iwate responded with their best stretch of the game in the third quarter. A 9-0 burst midway through the period, sparked by aggressive defence and a pair of steals that turned into easy points, cut the deficit to six and brought the arena to life. But Koshigaya's composure never cracked — a steadying mid-range jumper and a tough finish in traffic restored a double-digit cushion before the fourth quarter.

In the final period, the Alphas simply closed the door. They shot efficiently from the free-throw line, controlled the defensive glass and milked the clock on offence, stretching the lead to as many as 17 points before Iwate added a pair of late consolation baskets. The 13-point final margin flattered the home side slightly, given how much of the second half was played on Koshigaya's terms.

Standout Performers

Marcus Whitfield was the engine of the Koshigaya attack, finishing with 22 points, 11 rebounds and 4 assists while shooting 9-of-15 from the field. His ability to score inside and out made him a matchup problem all afternoon, and his work on the defensive boards limited Iwate's second-chance opportunities.

Point guard Daiki Sugimoto added 15 points and 7 assists with just one turnover, orchestrating the offence with maturity in the closing minutes. Ryota Hayashi was excellent off the bench with 14 points, including four three-pointers, while Taiki Nakamura chipped in 12 points and 6 rebounds.

For Iwate, Darius Coleman led the way with 19 points and 9 rebounds, battling hard inside despite constant double teams. Sho Takeda scored 16 points and Yuto Kaneshiro added 12, but the Big Bulls lacked a consistent third scoring option once Koshigaya tightened up defensively in the second half.
