"I had a good start in the second set so it's good for me. The second set went fast but the third set was close. I won the important point, 5-5, I broke the point," he told reporters after the match.

Last year's quarter-finalist, Becker admitted he was having a tough season this year that he had lost many matches and wanted to get back his confidence to win in Kuala Lumpur.

"Last year, I couldn't make it, lost in the first round. This year, I will try harder for the final... it is not easy to play. I am really happy to win today. I will meet Dimitrov next, I am sure it's going to be a tough match.

"But now, for me, it's time to enjoy the game. Tomorrow will be another day... and I'm gonna think about tomorrow's match. Dimitrov is a good player, I know him well, it's gonna be a tough match," said the 2013 MOKL champion.
