The Rogers Cup, both for the men and the women, is in the top tier of tournaments outside the Grand Slams. So generally speaking, most of the top players will show up.
Barring the last-minute withdrawals that always happen, that holds true this year as world No. 1 Serena Williams is the top seed in Montreal, and No. 1 Novak Djokovic the top seed in Toronto for the event. Both legs get under way with qualifying this weekend.
Here are the 16 seeds for the men's event. Two are missing, but both have highly legitimate reasons. World No. 8 Juan Martin del Potro of Argentina is rehabbing after wrist surgery and world No. 17 Alexandr Dolgopolov of Ukraine has just undergone knee surgery.
Men's seeds (world ranking in brackets)
1. Novak Djokovic (SRB) (1)
2. Rafael Nadal (ESP) (2)
3. Roger Federer (SUI) (3)
4. Stan Wawrinka (SUI) (4)
5. Tomas Berdych (CZE) (5)
6. David Ferrer (ESP) (6)
7. Milos Raonic (CAN) (7)
8. Grigor Dimitrov (BUL) (9)
9. Andy Murray (GBR) (10)
10. Kei Nishikori (JPN) (11)
11. John Isner (USA) (12)
12. Ernests Gulbis (LAT) (13)
13. Richard Gasquet (FRA) (14)
14. Jo-Wilfried Tsonga (FRA) (15)
15. Roberto Bautista Ague (FRA) (16)
16. Marin Cilic (CRO) (18)
As a result of the withdrawals, Croat Marin Cilic squeezes into the seeds on the basis of his new No. 18 ranking, a jump of four spots from last week because of a finals appearance at his home-country event in Umag last week.
No. 8 seed Grigor Dimitrov withdrew from this week's tournament in Washington, D.C. with the flu, but it's unlikely that means he'll miss Toronto. It's a much bigger tournament.
For the women, a similar story. The only top player missing so far is Romania's Simona Halep, who understandably is beginning her North American summer hard-court swing a little later than most.
Halep, who reached the French Open final and the Wimbledon semifinal, had to immediately turn around and play her home-country event in Bucharest on clay, right after Wimbledon, without a break. She battled some injuries through that stretch, which was particularly evident in her movement issues during the semi-final match at Wimbledon against Genie Bouchard.
Women's seeds (current rankings in brackets)
1. Serena Williams (USA)(1)
2. Li Na (CHN)(2)
3. Petra Kvitova (CZE)(4)
4. Agnieszka Radwanska (POL)(5)
5. Maria Sharapova (RUS)(6)
6. Eugenie Bouchard (CAN)(7)
7. Angelique Kerber (GER)(8)
8. Jelena Jankovic (SRB)(9)
9. Victoria Azarenka (BLR)(10)
10. Ana Ivanovic (SRB)(11)
11. Dominika Cibulkova (SVK)(12)
12. Caroline Wozniacki (DEN)(13)
13. Flavia Pennetta (ITA)(14)
14. Sara Errani (ITA)(15)
15. Carla Suarez Navarro (ESP)(16)
16. Lucie Safarova (CZE)(17)
Safarova has been practicing in Toronto the last few weeks; coach Rob Steckley is a Canadian. Williams also was practicing in Toronto last week, while filming a movie there. She is scheduled to play at the WTA Tour event in Stanford, California this week.
To have a Canadian in each of the draws, seeded, and seeded high enough to get a first-round bye is an extraordinary Canadian moment. It really wasn't long ago that the home-country players had to vie for wild cards into the main draw, where most wouldn't last all that long.
