Wins for Kerber and Keys in Singapore

Angelique Kerber and Madison Keys were victorious in their clashes at the WTA Finals in Singapore on Tuesday.

The world number one took a giant leap towards making the semi-finals of the event when she eased past Simona Halep in straight sets, winning 6-4, 6-2 in 83 minutes.

However, it was Halep that was the aggressor throughout, crunching 24 winner to Kerber's 11, but she also racked up 35 unforced errors which ultimately cost her the match. 

Kerber would break the Romanian in the opening game then consolidate to take a 3-1 lead. But the relentless Halep battled back to level matters at three games apiece. 

After fighting off a breakpoint in the eight game, Kerber transferred the pressure and broke Halep one more time on her way to winning the set.

A fiery Halep would get four opportunities to break in the second set, but Kerber would save them all and produce two of her own to notch up her second win of the WTA Finals.

"I'm feeling very good here,” said the two-time grand slam winner, who is at the top of the Red Group and one win away from the semi-finals.

"I'm really enjoying being back here on the center court and playing my best tennis. I think we played a great match today.

"I try every time I step on court to give my best. Of course every match here is tough – it's the best eight players in the world – and I'm just trying to focus on my game."

Later in the day, Madison Keys would earn her first ever win in the WTA Finals series, overcoming Dominika Cibulkova 6-1, 6-4 without even facing a break point.
