LYNN ? In the three-year history of the Agganis All-Star Men’s Basketball Classic, the South has dominated, including victories in the past two years by blowout margins.All that changed Monday night at the Paul F. Cavanaugh Field House.Wilmington’s Matt Bibeau led the way with 20 points as the North held on to win an overtime thriller, 78-77, giving the North its first victory in the tournament’s young history.”This was awesome,” Bibeau said. “There’s no better way to go end (your high school career). You can’t ask for better than an overtime game.”The overtime was a sluggish affair, with each team struggling with its shots after a basket by North Andover’s Sean McManus off the tip-off. The teams remained scoreless for most of the remainder of the two-minute period, as the South missed two three-point attempts in the final ten seconds. Two more free throws by Malden Catholic’s Corey Ryser put the North up, 78-74, with just over two seconds left.South MVP Paul Rose (20 points) of North Cambridge Catholic ended the game with a three-pointer at the buzzer for the final margin.”I had fun, but I really wanted to win,” Rose said. “I didn’t want to lose my last high school game.”The second half began with the North leading, 33-32, and stayed close the entire period. No team took more than a three-point advantage during the second half.With four minutes left and the South trailing by two, Lynn Tech’s Jose Rios hit a trey to put his team on top, 68-67. After a North free throw, Rios connected on a layup for a two-point South lead.Masconomet’s Kevin Van Lenten connected for a three for a 71-70 North lead before Winthrop’s Jonathan Murdock and Rose followed with layups for a three-point South lead. With less than ten seconds left, St. John’s Prep’s Ryan O’Connell tied the game with a three-pointer from the corner that sent the arena into a frenzy.After a missed attempt by Murdock, an O’Connell runner from half-court at the buzzer just rimmed out, forcing overtime.After the game, Bibeau said he enjoyed playing with such great competitors.”It’s always fun to play with kids who know exactly what they’re doing,” he said. “It was a great game with smooth play.”Although his team did not win, Rose, who was a member of the Division 3 state championship team at North Cambridge Catholic, said he enjoyed the contest.”It was fun; everybody deferred to each other and nobody was greedy,” he said. “Even though we lost, at least I still have my state championship to fall back on.”Rose dominated the competition early with eight quick points, sending his team to a 15-8 lead. Bibeau responded, though, leading his team with 14 first-half points en route to a 33-23 margin. The South ended the half with a 9-0 run, though, closing the gap to one point at the break.After the game, Bibeau said that playing in the Agganis Classic and winning the MVP was an honor to him.”It’s humbling,” he said. “With all these great players, it was a great opportunity to come and play.”The South won the previous three games in the series, with the closest margin coming in 2005 with a 75-72 win. The past two seasons were blowouts at 92-56 and 94-76, respectively.The Paul F. Cavanaugh Field House at Lynn English High School is named for the same man who lends his name to the Paul F. Cavanaugh Community Service Award. This year’s award recipient was George J. Marcopoulos.The game’s referees were Mark Shapiro, Jim Bennett and Dave Manalaysay.
