(Reuters) - Teenager Lydia Ko cruised into the winner's circle for a third time this season to claim her 13th career title on the LPGA Tour with a three-shot victory at the Arkansas Championship on Sunday. The world number one carded a three-under-par 68 for a tournament-record total of 17-under 196 in the 54-hole event at Pinnacle Country Club, three shots clear of Taiwan's Candie Kung (69) and American Morgan Pressel (71). "It wasn't the greatest ending to finish up with a six," Ko told Golf Channel.
