BATON ROUGE -- The LSU mens basketball team opened a 22-point second-half lead over Arkansas and held off the Razorbacks in the final minutes to win its first Southeastern Conference game of the season, 65-54, on Wednesday night at the Pete Maravich Assembly Center. LSU (10-17, 1-12 SEC) raced to an early double-digit lead and went up by as much as 22 when Zach Kinsleys fast-break dunk made it 50-28 with 9:06 to go. Courtney Fortson scored 18 points for Arkansas (14-14, 7-6), which played without 6-foot-9 senior forward Mike Washington. Washington did not make the trip because of an apparent ankle injury. Without him, Arkansas settled for outside shots and made only 34 percent from the field (18 of 53), including 9 of 28 from 3-point range (32 percent).
