Watson moves through at Edgbaston
Heather Watson moved into the AEGON Championships last 16 but fellow Britons Elena Baltacha, Anne Keothavong, Laura Robson, Melanie South and Tara Moore were all eliminated at the second-round stage in Birmingham on Wednesday.
Watson beat Baltacha 7-6 6-3 in their second-round clash and will face Roberta Vinci for a place in the quarter-finals after the Italian beat France's Virginie Razzano, who withdrew injured after losing the first set 6-3.
Watson, 20, was 4-1 down in the first set when rain forced the players off court, and she returned in far better form.
"I had a rough start to the year," said Watson, who lost her first four Tour matches of the season but reached the second round of the French Open - the best performance of any Briton - after coming through qualifying. She had not beaten Baltacha before. "It’s made me appreciate going on to the court and having the opportunity and taking it when I have it.
"I’m using it to learn and get stronger. I’m not going to go back to that."
British number one Baltacha appeared to suffer from having had to complete her first-round match against Kai-Chen Chang of Taiwan earlier on Wednesday after it carried over from Tuesday.
It was the first time Baltacha had lost to a fellow Briton in four years.
British number two Keothavong was ousted 6-3 6-4 by Chinese Jie Zheng who emerged victorious after a second set that featured five breaks of serve.
Zheng will face Andrea Hlavackova of the Czech Republic after she beat Mona Barthel 7-6 6-2.
Fifth seed Jelena Jankovic of Serbia accounted for South 6-1 7-6. South broke the world number 22 early in the second set only to then be broken twice; however she forced a tie-break with another break of her own.
The Serb next plays Australia's Casey Dellacqua after she beat Moore 4-6 6-4 6-1. Moore, ranked more than 200 places below her opponent, shocked her by taking the first set but committed several unforced errors in the decider to bow out.
Robson fought back to one set all against Kiwi Marina Erakovic but was broken at 5-4 down in the deciding set to lose 6-4 3-6 6-4.
Makarova will face Erakovic for a place in the last eight. Poland's Radwanska will next face American Irina Falconi after she beat Hungarian Timea Babos 6-0 6-4.
Italy's Francesca Schiavone suffered a surprise 7-5 6-4 defeat to Japan's Misaki Doi.
"I think I need to play much more on grass," 2012 French Open winner Schiavone said. "Every year I take really long time to be good and comfortable with my play.
"I am upset and it’s bad for me because I can play much, much better."
Doi will face Stephanie Foretz Gacon after the Frenchwoman beat Australia's Anastasia Rodionova 7-5 6-2.
Elena Vesnina will face Melanie Oudin in the next stage after they came through clashes with Christina McHale and Michelle Larcher de Brito respectively.
Russian Vesnina beat American McHale 6-1 1-6 7-5, while Oudin - also of the USA - won 6-3 6-4 against the Portuguese.
