NASHVILLE - Canada's Milos Raonic is one win away from his second title in as many weeks.

The hard-serving 21-year-old from Thornhill, Ont., defeated Benjamin Becker of Germany, 6-4, 6-4 in the Regions Morgan Keegan Championships semifinals Saturday.

He'll play Austrian Jurgen Melzer, who continued his amazing run with a broken right big toe by beating Radek Stepanek 6-4, 3-6, 6-3 in the other semi.

Raonic, who has not lost a set since the Australian Open and won at San Jose last week, is trying to win his first ATP 500 title.

He was runner-up to American Andy Roddick last year at the tournament.

Melzer ousted top seed John Isner to reach the semifinals. With his win over Stepanek, Melzer reached his fourth final in the United States and first since 2007 when he lost in Las Vegas to Lleyton Hewitt.

"Well, it's obviously very satisfying," Melzer said.

"I've played a great tournament so far, and reaching that final is something special. I haven't played a final since 2010. It was a tough match today. I mean he's obviously a tricky player. He knows what to do on the court, very offensive at times, just takes back a little bit the speed of his stroke. I had to stay focused. I had to play my game."

On the women's side, Marina Erakovic of New Zealand and Sofia Arvidsson of Sweden are set to play on Saturday in the Memphis International final.

Melzer helped Austria advance past Russia in the first round of the Davis Cup two weeks ago and came to Memphis early. He broke his toe when he got caught in a hotel bedspread on Feb. 16. Melzer has been icing the toe after each match, and he said the injury bothers him now only when he sprints and stops.

"But the good thing is most of my sliding I do on hard court I do with my left foot so it doesn't ... affect my game," Melzer said.

Melzer is in his 11th career ATP World Tour final and first since 2010 when he won his third career title at Vienna and also reached the final at Hamburg. Melzer also lost a semifinal that year to Rafael Nadal at the French Open.

He did it by remaining undefeated against Stepanek, though this was their first match that went three sets. Melzer broke Stepanek in the seventh game of the first set when the Czech double-faulted at deuce and when Melzer had the advantage, putting the Austrian up 4-3. Melzer then served out for the first set.

"When you lose a match like that you know you have your chances," said Stepanek, who decided to play in Memphis only on Tuesday after being ill. "I gave him a Christmas gift in the first set. You know it was a very poor service game of mine, and yeah, we don't play if something would be different. But the match went that way."

Stepanek broke Melzer to go up 4-2 in the second set and fought off two break points to hold serve and even the match.

The third set featured three straight service breaks with Melzer getting the first and the last. Melzer then had to rally from down love-40 to go up 5-2 before serving out for the win.

"I think the way I served out was impressive," he said.
