Kerber into second Wimbledon semi-final

London - Germany's Australian Open champion Angelique Kerber reached her second Wimbledon semi-final on Tuesday to edge closer to the world number one spot.

The fourth-seeded left-hander emerged victorious over Simona Halep, the fifth seed from Romania, 7-5, 7-6 (7/2) and will face either Venus Williams or Yaroslava Shvedova for a place in Saturday's final.

Kerber, who was also a semi-finalist in 2012, is now in sight of becoming the new world number one although she needs to win the title while seeing Serena Williams fail to make the semi-finals.
