semi-western grip

Pronunciation /ˌsɛmɪˈwɛst(ə)n ɡrɪp/

noun

US Tennis
  • A manner of gripping the racket in which (for a right-handed player) the bottom knuckle of the index finger is in contact with the right vertical panel of the racket handle and the heel of the hand with the bevel immediately clockwise from it, now used to generate topspin on shots.

    So named because the racket is held in a similar fashion to, but in a less oblique orientation than, the western grip.
