SHANGHAI -- Red-hot Andy Murray was an easy quarterfinal winner, while David Ferrer overcame Andy Roddick on Friday at the $3.24 million Shanghai Masters tennis event.
The second-seeded and reigning Shanghai champion Murray handled Aussie qualifier Matthew Ebden 6-3, 6-2 to record his 11th straight match win. The British star is seeking a third straight title on the ATP's Asian swing. He titled in Tokyo last week by ousting Rafael Nadal in the final and ran the table in Bangkok two weeks ago.
Murray, who hasn't lost since giving way to Nadal in the U.S. Open semifinals last month, defeated Swiss icon Roger Federer in last year's Shanghai finale.
The Aussie Open runner-up Murray's semifinal opponent on Saturday will be 47th-ranked Japanese Kei Nishikori, who dismissed 12th-seeded Ukrainian Alexandr Dolgopolov 6-4, 6-3 on Day 6.
"I feel like home here," Nishikori said. "It means a lot to play semis here. I'm really excited now. I think I started well today. I knew he [was] going to hit a lot of slice and I have to be careful. I was trying to not go for too much, just try to [be] steady on the court, and that worked."
Nishikori will become the highest-ranked Japanese player ever next week.
Meanwhile, a third-seeded Ferrer came from behind to erase the 10th-seeded former world No. 1 Roddick 6-7 (5-7), 6-2, 7-6 (7-2) on the hardcourts at Qizhong Tennis Center. The gritty Spaniard prevailed in just over 2 1/2 hours, as both players smacked 11 aces. Ferrer broke Roddick's big serve twice, while the American went 0-for-5 on his break-point chances.
"[In] the first set, I think we didn't play so good," Ferrer said. "I [am] playing with more confidence with my game, more consistency. [I am] more confident with my first serve [and] I am confident with my mind. This is very important, because some moments I didn't play really good."
A frustrated Roddick hasn't reached a final since February.
"I played okay [and] I thought he played pretty well," Roddick said. "I thought second and third sets he played at an extremely high level and served pretty well. You normally don't count on him making a lot of first serves, hitting aces. I felt like today he did that and got himself out of trouble a couple of times. When he's doing that, he's definitely tough to beat."
Ferrer will battle left-hander Feliciano Lopez in an all-Spanish semi here on Saturday. Lopez took out 15th-seeded German Florian Mayer 6-2, 6-4 on Friday. Mayer toppled the former No. 1 Nadal on Thursday.
Lopez is 6-4 lifetime against his compatriot Ferrer, but Ferrer has won two of their last three encounters, including a win this year at the Monte Carlo Masters. Lopez, however, topped Ferrer in the second round here in Shanghai two years ago and is 6-1 in their career hardcourt affairs.
The 2011 Shanghai champion will earn $620,000.
