A quick back-and-forth sequence in the Boston Celtics-Toronto Raptors game on Sunday gave former Texas A&M star Robert Williams a chance to bust out the windmill dunk.

He converted a Raptors turnover to an easy deuce to pad the Celtics 20-point lead late in the third quarter. The Celtics had a runaway lead by late in the fourth as they led by 24 points in Game 1 of the NBA’s Eastern Conference Semifinals played in the bubble in Orlando.

Williams had 10 points in 19 minutes of action including 5-for-5 from the field, 5 rebounds and 2 assists in the game.

Williams missed time earlier this season with a left hip injury. He’s averaging 5.2 points per game, and 4.4 rebounds.

Boston drafted Williams 27th overall with the team’s lone draft pick in the 2018 NBA Draft. He averaged 11.1 points on 59.1 percent shooting and 8.7 rebounds in 61 games (40 starts) over 2 seasons at Texas A&M.

As a sophomore in 2017-18, Williams led the SEC in rebounding with 9.2 boards per game. He was also named Co-SEC Defensive Player of the Year after producing a conference-best 78 blocked shots, the second-most by any player in school history.

Williams is from Shreveport, Louisiana, and as a freshman with the Aggies averaged 11.9 points (55.8 percent FG), 8.2 rebounds and 2.5 blocked shots. He earned Second Team All-SEC and SEC All-Freshman Team honors, in addition to being named the SEC Defensive Player of the Year.
