MEN’S BASKETBALL

U.S. International announced the signing of Derek Ivilein, a 7-foot center from Nigeria. Ivilein, a junior transfer from Florida A&M;, will redshirt next season. Gary Zarecky, USIU’s coach, said Ivilein contacted USIU after seeing the Gulls last season in the Ball State tournament, in which Florida A&M; also participated.

“He wants to be in a running game, and Florida A&M; plays more of a half-court offense,” Zarecky said.

Claude “Robbie” Robinson Jr., who was an All-San Diego Section basketball player at Madison High School last season, was sentenced to perform 250 hours of community service as a condition of three years’ probation on a conviction for unlawful sex with a minor.

Robinson pleaded no contest to the misdemeanor charge of having sex with a minor. Municipal Court Judge Patricia Cowett said she felt the incident did not involve force or violence but that even though the act was consensual, it was a crime under state law.
