Top seed David Ferrer and second seed Feliciano Lopez will contest Sunday's Malaysia Open final after the Spanish pair won their respective semi-finals on Saturday.
Ferrer, who is currently in eighth place in the race for qualification for the ATP World Tour Finals in London next month, had to call on all his resolve in his match against the unseeded Benjamin Becker, winning 3-6, 6-2, 6-4 against the German outsider.
Ferrer needed more than two hours to eventually gain the ascendancy in the match against Becker while saving 11 of the 13 break opportunities his opponent had.
Lopez had a similarly difficult match against Australia's Nick Kyrgios – who is quite the crowd favourite in Kuala Lumpur since his mother is from Malaysia – eventually overcoming the outspoken 20-year-old 7-6(2), 7-6(5).
Lopez notched 12 aces in his match while Sunday's final will be his second of the season and the 15th clash against Ferrer.
Lopez has won six of their previous 14 encounters, although the last one of those triumphs came in 2011, as Ferrer won the last five clashes.
"The first (tie-break) I took advantage of. It was clear that I normally would win that one but the second one was very tight," Lopez said of his match against Kyrgios.
"After 5-4 with two, three crazy points … I think I have to be proud of the way I played because he (Kyrgios) was really playing well today.
"Experience is always a good thing to have but today the match could have gone either way. If you play a tie-break against someone who's such a good server as Nick you know it's going to be tight.
"It's going to be a battle, we (Lopez and Ferrer) usually go three sets. But considering the level I'm playing at now I still think I'm playing better myself than I was playing in February."
