The Oklahoma City Thunder exercised its third-year contract option on guard Josh Giddey, who was all-rookie second team last season despite missing the last 22 games with a hip injury.
The Thunder also exercised a third-year option on guard Tre Mann and a fourth-year option on forward Aleksej Pokusevski.
The 6-foot-8 Giddey, a native of Australia, averaged 12.5 points with 7.8 rebounds and 6.4 assists in 54 games last season. He became the youngest player to record a triple-double at 19 years, 84 days when he accomplished the feat on Jan. 2 against the Dallas Mavericks.
Mann, 21, scored 10.4 points with 2.9 rebounds in 60 games last season, also his first in the NBA. Pokusevski, 20, in his second season with the Thunder last season, scored 7.6 points with 5.2 rebounds in 61 games.
