Eagerly grasps hurdle, having landed on bottom (5,2)

I believe the answer is:

jumps at

'eagerly grasps' is the definition.

'hurdle having landed on bottom' is the wordplay.
'hurdle' becomes 'jump' (I've seen this before).
'having' says to put letters next to each other.
'landed on bottom' becomes 'sat'.
'jump'+'sat'='JUMPS AT'

I've seen this clue in The Guardian.
