Star baseball player's decoration hung by window (10)

I believe the answer is:

suncatcher

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

'decoration hung by window' is the definition.
I don't know anything about this answer so I cannot tell whether this works.

'star baseball player's' is the wordplay.
'star' becomes 'sun' (the Sun is a star).
'baseball player' becomes 'catcher' (catcher is a kind of baseball player).
'sun'+'catcher'='SUNCATCHER'

Can you help me to learn more?
