Heather Watson reached the last 16 of a Grand Slam in singles for the first time as she overcame Kaja Juvan to reach the Wimbledon fourth round.

The British world number 121 raised her arms aloft in celebration as she withstood a late Juvan resurgence to convert her first match point in a 7-6, 6-2 win over the Slovenian.

Watson plays 97th-ranked German Jule Niemeier in the fourth round.
