Kashyap who has been in stellar form this season started on a high note with his power smashes proving no match for the 37-year-old Korean. Even though the Lee gave him a tough fight it was the Indian who bagged the opening game.
In the second game, Lee got his act together and was quick off the blocks to head into the interval with an 8-3 lead. After the breather, Kashyap won three points on the trot to reduce the lead and was not in the mood to go down so easily.
Lee, the oldest player to win a match in the PBL came out a different player altogether and got on to the front-foot from the word go. He raced to an 8-3 lead and his combination of smashes, drop and deceptive cross court hits were too much the Indian to handle.
Though Kashyap tried to stay on in the hunt after the change of ends and saved six match points, Lee did not give him any chance of a comeback and cruised to win the match and give his side the advantage.
