Konta was triumphant 6-3 6-4 against Germany’s Kerber to reach the Aegon International semi-finals. Both Konta and British number three Watson reached the semi-finals by winning twice on Thursday .
Konta was victorious 7-5 3-6 6-4 against French Open champion Jelena Ostapenko in the pre-quarters, while 25 year old Watson beat Russian 14th seed Anastasia Pavlyuchenkova 6-4 6-3.
The world number seven has won only one main-draw match at the All England Club and lost out in last year’s second round to 2014 finalist Eugenie Bouchard. Victories over Ostapenko and Kerber moved her within two wins of her first tour title on grass.
Konta impressed everyone against Kerber and dominated the two-time Grand Slam champion’s serve. She even slipped near the baseline. But aftyer 10 minutes break she fought like a tigeress and won the match. Kerber came around the net to help her contemporary before medical staff arrived and helped the British number 1 continue after a stoppage.
“I slipped and hit my head and it’s a bit sore,” said the Australia-born player, whose family moved to Eastbourne when she was a teenager. “It’s been a busy afternoon, we’ve played a lot of tennis and I’m looking forward to recovering the best I can.”
Konta will play Czech third seed Karolina Pliskova, who beat Russia’s Svetlana Kuznetsova, in the second semi-final on Friday
