Emma Raducanu cruised into the Miami Open quarter-finals after brushing aside American 17th seed Amanda Anisimova in straight sets.

Raducanu’s first last-eight appearance at a WTA 1000 tournament was secured in emphatic fashion as she dominated her opponent to triumph 6-1 6-3.

The British star’s best run since being crowned 2021 US Open champion continued as she controlled the match throughout.

Raducanu did not drop a point on her serve in the first set, which underpinned an impressive performance that saw her move into the top 50 of the world rankings.

Raducanu broke her opponent’s serve in the opening game as she brought immediate intensity to the last-16 clash, then repeated the feat and moved 3-0 ahead.

Raducanu had complete control during her first two service games, and Anisimova struggled to make any headway, being involved in an exchange with the umpire before holding her serve and cutting the deficit to 4-1.

The American cut a frustrated figure, and Raducanu closed out the first set after just 24 minutes with a third break of serve.

Anisimova’s problems deepened before the second set began, requiring treatment on her right wrist and having it heavily strapped before the match resumed and Raducanu immediately held serve.

Raducanu’s dominance continued when she broke serve for a 3-1 advantage, and the next two games also went against serve as she closed in on victory that was achieved after 68 minutes.
