After Shamorie Ponds of the St. John’s Red Storm fed Mustapha Heron for a rim-rattling dunk before a capacity crowd at Carnesecca Arena in Queens on Tuesday night, Marvin Clark II walked to the center of the court and stood in the middle of the team’s red logo.

He faced a crowd of more than 5,000 people, including the tennis legend John McEnroe, and waved his arms to stoke the cheers.

Like many of the St. John’s men’s basketball players this season, the 6-foot-7 Clark had seen this sort of thing done before — in other places. He played in a Final Four for Michigan State and Coach Tom Izzo in 2015, notching 10 minutes as a freshman when the Spartans lost to Duke. After his sophomore year, he transferred to St. John’s, where he believed he could play a larger role.

Mission accomplished. On Tuesday night, Clark scored 22 points and grabbed 7 rebounds in an 89-69 win over No. 16 Marquette, the most impressive victory this season for Coach Chris Mullin’s resurgent team, which is 13-1 over all entering an early Big East matchup with Georgetown (11-3) on Saturday in Washington.
