Emma Raducanu has said while her defeat to Aryna Sabalenka is tough to take, she feels motivated to keep improving having given the world No. 1 a serious test at Wimbledon on Friday.

The controversial call, which Raducanu questioned, was a first serve by Sabalenka at 2-4, 15-0, which did appear to miss the line upon replay. The serve ultimately led to Sabalenka going up 30-0 in a pivotal set during the match, helping her stage a comeback after going down early.
