Young talents Kyrgios and Zverev impress

Nick Kyrgios has continued his red-hot form with a straight-sets fourth-round win against eighth seed David Goffin at the Miami Open.

Kyrgios’s 7-6(5) 6-3 victory propelled the 21-year-old Australian into his fourth quarterfinal in as many events.

Big tennis from @NickKyrgios.

That was calm, sober, confident, professional. So good from Kyrgios.

Gimelstob on Kyrgios' level tonight: "This is the only tennis that can challenge Federer."

The No.12 seed now faces fellow young gun Alexander Zverev, the No.16 seed who upset top-seeded birthday boy Stan Wawrinka 4-6 6-2 6-1 earlier today. Impressively, it was the German’s third consecutive win against a top five-ranked opponent.

The 19-year-old Zverev becomes only the fifth teenager since 2007 to reach an ATP Masters 1000 quarterfinal. American Sam Querrey (2007), Croatian Marin Cilic (2oo8), Latvian Ernests Gulbis (2008) and Croatian Borna Coric (2016) also achieved the feat.

Kyrgios and Zverev played their first professional match at Indian Wells earlier this month, which the Australian won in straight sets.
