Nishikori Cruises Into the Fourth Round

Japanese 16th seed Kei Nishikori continued his impressive run at the Australian Open, dismantling Russia’s Evgeny Donskoy 7-6(3), 6-2, 6-3 in two hours and six minutes to reach the fourth round.

The 23-year-old won 77% of his first serves and made 29 winners compared with his opponent’s tally of 13. “I think I’m in good shape,” smiled Nishikori, adding that his confidence is growing with each victory.

dismantleはから「（衣服などを）はぎ取る」「 〜を取りこわす、ばらばらにする」という意味ですが、ここでは「撃破する」あたりでしょう。それにしてもスポーツでは大げさな動詞表現が好まれますね。（GP）
