Here's a Korea Times article about Lu's win
In Sunday’s final of the $125,000 ATP Samsung Securities Cup Challenger at Olympic Park in Seoul, the difference between 44th ranked Lu Yen-hsun of Taiwan, and Kevin Anderson, No. 64, of South Africa, was tiny, but evident. Lu was steadier, and at the important points, rose to the occasion. He broke his 24-year-old opponent’s serve once in each set, taking the 18,000 winner’s check in one hour, 38 minutes.
Anderson, 2.3 meters, bombed nine aces to Lu’s two. But it was the 1.8-meter Lu - who beat Andy Roddick at Wimbledon this year -making several acrobatic saves from well behind the baseline, patiently moving Anderson side to side until he could attack.
