Second tee: top player adopting new address (6)

I haven't cracked this one yet — but the brilliant team at Fifteensquared have:

S (second) + T (tee) + ACE (top player) round N (new) – I can’t quite work out the noun / verb grammar here: Chambers has, for ADDRESS (verb) ‘to take one’s stance in preparation for striking (a golf ball)’ – but also, as a noun, ‘act or mode of addressing’; do golfers use it as a noun in this context?
