D. J. Carton

On April 15, 2020, Carton committed to continue his career at Marquette. He is expected to sit out his first season with the team due to transfer rules.

Carton was named the Big Ten preseason freshman of the year, but Florida State transfer C. J. Walker started ahead of him at point guard to begin the season. Carton scored a season-high 19 points on December 15, 2019, in a 84–71 loss to Minnesota. On January 26, 2020, Carton scored 17 points and had three assists in a win over Northwestern. He decided to take a leave of absence from the team on January 30, citing mental health issues. Carton averaged 10.4 points and 3.0 assists per game as a freshman, shooting 40% from 3-point range. Following the season, he opted to transfer from Ohio State.

Growing up, Carton's family moved several times before settling in Geneseo, Illinois. He excelled at baseball and could throw 75 miles an hour by seventh grade. He also played running back on the football team, but a rotator cuff injury forced him to concentrate on basketball. Carton moved to Bettendorf, Iowa after eight grade and he attended Bettendorf High School, where he became a starter on the basketball team as a sophomore. As a junior, he was a first-team all-state pick, averaging a school-record 26.3 points per game to go with 5.7 rebounds and 3.3 assists per game. He scored 49 points against Davenport West High School during his senior season. Carton led the Bulldogs to a 21–2 season and the top of the Class 4A state rankings before they fell to Dubuque Senior High School in the state Sweet 16 despite 27 points from Carton. As a senior, Carton averaged 24.4 points, 7.6 rebounds and 6.0 assists per game. Carton finished his career as the all-time leading scorer with 1,198 points and was among the school's all-time leaders in rebounds (372) and assists (257). He was named Co-Iowa Mr. Basketball in 2019, alongside Jake Hilmer. In AAU play, Carton competed for the Iowa Barnstormers before joining the Quad City Elite. Ranked the 21st bast player in his class and a five-star prospect, Carton committed to Ohio State on July 14, 2018, over offers from Indiana, Michigan, Iowa, Marquette and Xavier, among others.
