Anna Chakvetadze eased into the last four of the US Open with a comprehensive 6-4 6-1 win over Israeli 18th seed Shahar Peer.
Chakvetadze was ruthless against Peer
The first four games went with serve until Peer went 3-2 up and then held her serve to love, but that was as good as it got for the Israeli.
The Russian then rattled off ten of the next 11 games as Peer's game crumbled in spectacular fashion.
Chakvetadze showed no mercy in reaching her first Grand Slam semi-final.
The sixth seed faces fellow countrywoman Svetlana Kuznetsova in the last four after she brushed aside the challenge of Hungarian teenager Agnes Szavay 6-1 6-4 in their quarter-final.
Peer claimed the first break in each set, but those were the only real highlights for her as she was swept aside by Chakvetadze, who has already won four titles this season.
After losing the first set, she broke the Russian in the opening game of the second set but this proved to be a false dawn as the sixth seed showed her ruthless side to power into the last four.
"I was so nervous before the match. Even though it was straight sets it was a really tough match," said Chakvetadze afterwards.
"In the second set I just started to play more aggressively and Shahar's level went down a bit, so I took my opportunity."
Chakvetadze has lost both her previous meetings with Kuznetsova, and has used this as a subtle way of putting pressure on her opponent.
"She's a favourite in this match, so I have nothing to lose and no pressure," she said.
"For me it's much easier to play with no pressure, so I will try to do my best."
