If Canadian Milos Raonic wishes to advance past the second round at the Rogers Cup — and he does — he'll need to knock a Sock off.
Raonic, the world No. 6 who is seeded sixth at the Masters 1000 event in Toronto, will open his tournament on Wednesday night against American Jack Sock.
Sock, ranked 60th in the world, advanced by beating Jurgen Melzer, 6-1, 6-3, on Tuesday afternoon.
Raonic, 23, and Sock, 21, have a recent history of close matches. Raonic edged the Tampa, Fla. native in a tiebreaker at the Citi Open in Washington en route to his first ATP World Tour win of the season, and earlier at Wimbledon. Raonic also beat Sock in Miami earlier this year, as well as in Cincinnati last year.
