Freshman guard Stephon Castle scored a season-high 20 points and top-ranked UConn held off Providence 74-65 Wednesday night in a foul-filled Big East battle. Tristen Newton added 16 points and 11 rebounds, and Cam Spencer scored 15 as the Huskies (19-2, 9-1) won their ninth straight in a game that included 48 fouls — 29 of them on Providence. “These are steel cage matches,” UConn coach Dan Hurley said.
