High-jumper in sport? (7)

I believe the answer is:

cricket

I'm a little stuck... Click here to teach me more about this clue!

'sport?' is the definition.
(I know that cricket is a type of ball game)

I don't understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for cricket that I've seen before include "Game - "basically baseball on Valium" (Robin Williams)" , "English game or chirping insect" , "Jumping insect" , "Summer sport" , "Insect - sport" .)

I've seen this clue in The Telegraph.
