Johannesburg - Kevin Anderson will face Argentine world No 16 Juan Monaco in the quarter-finals of the US Men's Clay Court Championships in Houston, Texas, on Friday.
Anderson, the SA number one, was made to work hard for a 7-6 (7/3), 3-6, 7-6 (7/2) victory over American Sam Querrey in the second round on Thursday.
Monaco, meanwhile, swept past Tsatsuma Ito of Japan to coast into the last eight, and the South African will face a tough task in progressing to the next round as he goes in search of his second ATP Tour title, having won at Delray Beach last month.
