Russian third seed Dmitry Tursunov came through two matches on Saturday to book a place in the final of the Indianapolis Championships against Canada's world number 109 Frank Dancevic.
Dancevic produced a stunning 6-4, 7-6 win over top seed Andy Roddick in their semi while Tursunov came through 6-1, 6-4 in his rain-delayed quarter-final against Japanese amateur Kei Nishikori before seeing off American Sam Querrey 7-6, 6-2 in the semi.
It was a bad day for the leading seeds with Roddick's humbling and second seed James Blake going down 7-6, 6-7, 7-6 in another delayed last-eight match to Querrey, who posted 34 aces in the encounter, including nine in a row in the second set.
"Frank's a similar type of player to me, going for lot's of shots," said Tursunov, who beat the Canadian in their only meeting at Queen's earlier this year. "If he's making his shots, there won't be much I can do about it."
Tursunov, who never had his serve broken in beating Querrey, won the final four games from 2-2 in the second set.
"I can't be sad about it (making the final)," said Tursunov, looking for a second career title. "Sunday is supposed to be a day off, but I'll make an exception."
Dancevic drove from his Niagara Falls home when he was told late last week he was the last player to receive direct acceptance into the Indianapolis main draw and he is now in his first career tour final.
"This was probably the best victory of my career," said Dancevic, who claimed his first top ten scalp with the Roddick victory.
SURPRISE WEEK
"This is definitely a surprise week. I would've been happy to be in the final of a Challenger (event) this week and now I'm in the final of a tour event."
Dancevic is vying to be the first Canadian to win a tour title since Greg Rusedski won at Newport in 1993 and at Seoul in 1995 before deciding to become a British citizen.
"I served horribly today - I served pretty badly the whole week," Roddick said.
"I didn't have much to give out there," he said. "I wish I had a reason for you. I don't know why. I wasn't feeling that well."
Roddick lost serve in the 11th game of the first set at 30-40 when Dancevic hit a winning forehand crosscourt.
When Roddick lost his serve in the first game of the second set, he lost his cool and slammed a ball out of the stadium for which he received a warning for ball abuse.
Roddick broke back and the second set went to a tiebreaker where Roddick only won one point -- the opening point -- with an ace.
