SYDNEY - Top seed Agnieszka Radwanska didn't even get the chance to defend her title at the Sydney International, it only took 92 minutes as Bethanie Mattek-Sands ousted her in the 2nd round on Tuesday.
Agnieszka Radwanska ranked world number 5 was upset by the American qualifier 7-5 6-2.
"She was really playing aggressive," Radwanska who was suffering from a slight shoulder injury said.
"Didn't matter if it was my first serve, second serve, or anything, she was really going 100 percent for every ball."
Radwanska had a poor end to the season in 2013, losing all three round robin matches at the WTA championships though she won all three matches at the Hopman Cup in Perth last week.
"I really had a lot of good matches last week," the 24-year-old Pole added.
"It's not like I'm playing bad. I'm not worried about that. I just think not my day (and)... sometimes you have to lose.
"I think every week is different story. You start over and over again.
"Every tournament isn't the same thing. You're not winning every week every match. Normally you just to have to start again, not really think what was happening in the last week."
Mattek-Sands will now face fellow American Madison Keys in the quarter-finals.
"She's a great upcoming player, plays aggressive shots, big serve, we've had some battles in the past, so I'm looking forward to tomorrow," Mattek-Sands said of Keys.
