Mike Anderson’s crucial 2020 recruiting class is starting to take shape.

It began a month ago with the commitment of Brooklyn point guard Posh Alexander. It continued Sunday night with the addition of junior college All-American shooting guard Vince Cole, giving the new St. John’s coach a promising future backcourt.

The 21-year-old Cole verbally committed at the end of his official visit, deciding there was no need to wait for his season to play out.

“It was a really easy decision,” the 6-foot-6 Cole, who will have two years of eligibility, said in a phone interview. “I’ve known [assistant] Coach [TJ] Cleveland and Coach Anderson for a really long time. New York is a great place. Coach Anderson loves JUCO guys and gets them to where I want to go.”

Cleveland and Anderson began recruiting Cole when he was in high school and they were at Arkansas. They stayed in contact when he wound up in junior college and extended him a scholarship in July after they had come to St. John’s.

Anderson and Cleveland recently saw Cole at South Carolina-Salkehatchie, and he felt comfortable during his stay in the city. He got to see Madison Square Garden and Saturday night, the entire team went to Anderson’s house on Long Island after a charity event raising money for cancer research.

“St. John’s had everything I needed as a player and person,” said Cole, a Charleston, S.C., native who was also being recruited by Oregon State, North Carolina State, Fresno State, Illinois State, Buffalo, Coastal Carolina and Akron, among others. “They’re just together all the time. You can tell the relationships that are being built.”

Cole averaged 18.7 points and 6.2 rebounds last season, shot 47 percent from the field and 44 percent from deep. His game has expanded since getting to junior college, developing into a better defender and a well-rounded scorer capable of posting up, getting to the basket and shooting from deep. He also has improved as a ball-handler and will initiate offense for USC-Salkehatchie at times.

“He’s an effortless scorer at all three levels,” USC-Salkehatchie coach Jake Williams said.

St. John’s will need him to produce immediately. Mustapha Heron will graduate, opening up a scoring void.

“I need to be an instant impact guy,” Cole said. “I know if I work hard, I can have the opportunity to do that.”
