LOS ANGELES (AFP) — Shai Gilgeous-Alexander scored 34 points as the Oklahoma City Thunder punched their ticket to the playoffs with an impressive 118-112 victory over the reigning champion Boston Celtics in a potential National Basketball Association (NBA) Finals sneak preview on Wednesday.

Gilgeous-Alexander enhanced his credentials as favorite for the Most Valuable Player award with a superb performance to silence Boston’s TD Garden home crowd in an absorbing duel settled by a burst of fourth-quarter Thunder scoring.

The Canadian point guard shot 11-of-20 from the field to finish with five rebounds, seven assists and 34 points, including 10-of-11 from the free throw line.

The win lifted Western Conference leaders Oklahoma City to 54-12 and guaranteed their place in next month’s playoffs.

Wednesday’s win over a vastly more experienced Boston lineup marked another mature display from a Thunder side that is the youngest in the league.
