Britain\'s Heather Watson won a place in the main draw of the Olympic women\'s singles on Tuesday after Ukraine\'s Alona Bondarenko withdrew due to a right knee injury. Bondarenko has not played since October 2011 because of the injury. Former US Open junior champion Watson was the first reserve in singles following her rise up the world rankings to 67 after reaching the third round at Wimbledon -- also the venue for all the Olympic tennis tournaments -- where she lost to runner-up Agnieska Radwanksa of Poland. Watson is the third British woman in the London Olympics singles event, alongside Anne Keothavong, Elena Baltacha and is also playing in the doubles with Laura Robson.
