Wildcard Kyrgios cruises into Halle semis after blowing away Busta

• Kyrgios into semis after defeating Pablo Carreno Busta 6-4 6-2
• Australian No 2 on the verge of reaching his first grass-court final

With no histrionics and no dramas, just pure, no-nonsense enjoyment, Nick Kyrgios has roared into the semi-finals of the Halle grass-court tournament.

The Australian, so often sidetracked from his own brilliance by unnecessary distractions, was the model of businesslike concentration on Friday - with just the odd showman's trick chucked in - as he blew away Top 20 baseliner Pablo Carreno Busta 6-4 6-2.
