同義詞
  • full toss

    a broader term for any ball that reaches the batter without bouncing; a beamer is the dangerous high kind

  • high full toss

    describes the height directly, while beamer often carries a stronger sense of danger

用法筆記

Usually said of a dangerous or illegal delivery, not an ordinary high ball. A beamer reaches the batter without pitching first, so it can rise into the body area quickly.

✅It was a beamer, so the umpire called a no-ball.
💡a bouncer rises after bouncing, but a beamer does not pitch first.
