Jenson Brooksby and Katie Volynets lead US surge at Australian Open

• Eight US men into third-round for first time since 1996
• Qualifier Volynets upsets No 9 seed Veronika Kudermetova

Jenson Brooksby regained control of his emotions after a third-set slip-up on the way to a 6-3, 7-5, 6-7, 6-2 victory over No 2 Casper Ruud and a spot in a surprisingly US-filled third round at the Australian Open.

I was getting a little more frustrated out there that I didn't close it out, and my mentality was changing a little bit," said the 39th-ranked Brooksby, who sipped pickle juice in the fourth set at Rod Laver Arena. Those are the situations you have to handle sometimes in matches, and you're going to face. I think the biggest question is: How do you respond? I just told myself to reset."
