Billy Richmond III scored nine of his 16 points in the second half, allowing 10th-seeded Arkansas to withstand a comeback from second-seeded St. John's and earn a 75-66 victory in Saturday afternoon's West Region second-round action in Providence, R.I. The Razorbacks (22-13), who are 5-1 in their last six games, advanced to the Sweet 16 for the fourth time in five years despite shooting just 2-of-19 from 3-point range and four players getting into foul trouble. In a legendary coaching matchup with Rick Pitino of St. John's (31-5), John Calipari earned his 59th all-time NCAA Tournament win -- the most among active coaches.
