In the critical 4th game of the NBA Western Conference Finals, the San Antonio Spurs will face the Oklahoma City Thunder. Scott Foster, Curtis Blair, and Nick Buchert have been assigned as referees for this important game. Oklahoma City Thunder leads the series 2-1 and defeated San Antonio 123-108 in the previous game. Foster is known among fans by the nickname 'The Extender.' This nickname stems from the perception that teams trailing in games officiated by Foster are more likely to extend the series. However, according to Sporting News' 2020-2025 NBA playoff data, the winning rate of the trailing team in games refereed by Foster is around 50%, which is not as high as the nickname implies. Foster also officiated the 4th game of the first-round series between the Orlando Magic and Detroit Pistons. Although the Magic took a 3-1 lead in that series, the Pistons won the series in 7 games. The 4th game between the Thunder and Spurs is seen as a crucial turning point that will determine the fate of the series. The game will start on Sunday at 8:00 PM ET.
