(AP) — Kentucky coach John Calipari can point to the reason why freshman guard De'Aaron Fox has blossomed into the Wildcats' offensive leader at the most crucial time of the season. Fox is coming off the best scoring game of the NCAA Tournament with his career-high 39 points helping Kentucky (32-5) move to its accustomed place in the regional finals Sunday playing top-seeded North Carolina in the South. Ball declared for the NBA draft after Friday's loss. In the six postseason games including the Southeastern Conference Tournament, the 6-foot-3 guard from Houston has averaged 23 points, while connecting on 57 percent of his shots. "There is a reason he is who he is, and the hype he has around him," UCLA guard Bryce Alford said after Friday's loss to the Wildcats. After a couple answers about planning for the national title that could make the Carolina bulletin board, the rest of the Wildcats lightheartedly shut him down. The Wildcats took a 36-33 halftime lead into the locker room with Fox scoring 15 points and making seven of his 12 shots. Junior Justin Jackson, North Carolina's leading scorer, said Fox showed signs of being good when they played for the same AAU team in Texas.
