St. John’s offseason isn’t off to a great start.

Forward Aaron Wheeler has opted to bypass his final year of eligibility and go pro, his father Bill told The Post.

The move isn’t a surprise as the 23-year-old Wheeler already has graduated from college.

He transferred to St. John’s after three seasons at Purdue, and had a strong season following a slow start. Wheeler could’ve played a fifth season, since the 2020-21 campaign didn’t count because it was played during the height of the COVID-19 pandemic.

The 6-foot-9 wing averaged 10 points, 4.7 rebounds and shot 38.5 percent from 3-point range. He broke the news to coach Mike Anderson on Tuesday afternoon, according to his father.
