It was a clean sweep for the three Long Island-based Catholic high school basketball teams that competed at the fourth annual Oceanside Christopher Christmas Challenge Dec. 17 at Chaminade H.S., Mineola. Kevin Bowles had 16 points, including three 3-pointers, and six rebounds to propel Kellenberg Memorial, Uniondale, to a 66-37 victory over Oceanside. Mike Walsh scored 13 points and grabbed 14 rebounds as Chaminade overcame a late-game deficit to beat Xavier, Manhattan, 52-47. Jason Oder scored 21 points, including three 3-pointers, and had 10 rebounds as Holy Trinity Diocesan, Hicksville, defeated South Side, Rockville Centre, 67-54. Oceanside Christopher dedicated this year’s Christmas Challenge to Jim Quinn, Chaminade’s veteran teacher and hoops coach. A 1968 Chaminade grad, Quinn has taught and coached at the school for 40 years. He has been the varsity basketball coach for the past 25 seasons, compiling more than 400 victories along the way. Coach Quinn, who will retire at the end of the academic year, is shown with Joseph Garay, president and CEO of Oceanside Christopher. In action, Kellenberg’s Bryan Gellineau, who had eight points and 10 rebounds, eyes the basket; Chaminade’s John Gallego, who had 12 points, five assists and three steals, drives to the basket; Holy Trinity’s Isaiah Rowe drives past South Side’s Dane Flaherty.
