LONDON – The third-round match between Canadian Milos Raonic and American Jack Sock at Wimbledon was postponed Friday due to rain.

The two are scheduled to play Saturday.

Raonic, from Thornhill, Ont., is seeded sixth at the Grand Slam tournament. Sock is 27th.

Raonic topped Italy’s Andreas Seppi on Thursday to advance to the third round. That match had also been postponed a day because of weather.

Four other third-round men’s matches were suspended mid-play on Friday, including World No. 1 Novak Djokovic’s match against Sam Querrey. Querry, the 28th seed, was leading Djokovic 7-6 (6), 6-1 when play was postponed.

Because of all the wet weather this week, the All England Club said matches will be played on the middle Sunday for only the fourth time in Wimbledon’s 139-year history. The tournament is facing a backlog of matches, including some second-rounders that have not been completed.

Eugenie Bouchard of Westmount, Que., is scheduled to play Dominika Cibulkova in third-round women’s play on Saturday.
