The French Open champion will be battling for a place in the quarter finals, and an eleventh straight win in grand slam tournaments, against Ukraine's Elina Svitolina.
Svitlona is renowned for her consistency and is currently ranked fifth in the world, so will present a formidable challenge. The pair have never previously met.
Former Wimbledon favorite and now TV pundit Mats Wilander has been talking up Ostapenko's chances.
As ever, you will be able to watch the match live on LTV7 and LSM's Latvian service, with coverage starting from 13:30 Riga time. However, tennis fans should be warned that rain is forecast for so-called 'Manic Monday' in London, so schedules are likely to be disrupted.
On July 8 Latvia's contender in the men's competition, Ernests Gulbis, lost in straight sets to Novak Djokovic during a match in which he was hampered by injury but still put up a good show.
Gulbis' return to form has belied his lowly WTA ranking and hopefully will be the start of a renaissance from one of the most enjoyable players to watch on the men's circuit.
