- Unseeded Alison Riske became the first player to reach the quarter-finals by upsetting sixth-seeded Italian Flavia Pennetta 6-1, 7-6 (7/3) at the Connecticut Open on Tuesday.

"There are a lot of top players here. I'm definitely proud to be the lone American left, and hopefully I can keep it rolling," she said.

"I knew that I had to attack her second serve because she places her first serve so well.

"I felt like I was going to get looks at it at any moment, so I just kind of stuck with it, and I ended up returning well today. I just played solid."

In other second round action Tuesday, Czech Barbora Zahlavova Strycova eased past France's Caroline Garcia in straight sets 7-5, 6-2.
