rap out

UG先生，GPくんに続いてイチロー選手の偉業に関する記事から。the Japan Times Onlineの記事の見出しでは，rap outという表現が用いられています。rapには「（…を）軽くたたく, トントンと打つ」（『プログレッシブ英和中辞典』小学館）という意味があり，to hit or knock something quickly several times（LDOCE）と英英にもありました。このrapを使うことで「ヒットを重ねた」というニュアンスが感じられます。（Koyamamoto）

Ichiro raps out 4,000th career hit
NEW YORK – Ichiro Suzuki slashed a single the opposite way with his unique swing for the 4,000th hit of a career split between Japan and the major leagues.
The 39-year-old Ichiro hit a liner off Toronto’s R.A. Dickey that bounced just beyond diving third baseman Brett Lawrie in the first inning Wednesday night for the milestone hit.
Ichiro broke a tie with Lou Gehrig when he got his 2,722nd major league hit in his 13th season. The speedy outfielder amassed 1,278 hits in nine seasons with Orix of the Pacific League.
