Olympian sprinter heard Misha's tin rattling (4,5-5)

I believe the answer is:

dina asher-smith

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

'olympian sprinter' is the definition.
I know nothing about this answer so I can't tell whether it can be defined by this definition.

'heard misha's tin rattling' is the wordplay.
'rattling' indicates an anagram (letters rattle around).
'heard'+'mishas'+'tin'='heardmishastin'
'heardmishastin' with letters rearranged gives 'DINA ASHER-SMITH'.

Can you help me to learn more?
