Two other Americans joined Harrison on the way out Thursday with exits against highly seeded men: Jack Sock lost to No. 2 Kei Nishikori of Japan 7-5, 6-2, while Tim Smyczek was beaten by No. 3 Tommy Haas of Germany 3-6, 7-5, 6-3 in a match suspended Wednesday after the opening game of the final set.
In the afternoon’s biggest surprise, Marinko Matosevic of Australia beat No. 4 Milos Raonic of Canada 7-5, 7-6 (7).
Nishikori was to take on No. 16 Marcos Baghdatis later Thursday, while Haas had to go back out to face No. 13 Ivan Dodig at night.
No. 7 Kevin Anderson eliminated James Duckworth 6-3, 3-6, 6-4, then was scheduled to play Mardy Fish of the United States later. Fish, meanwhile, withdrew from next week’s tournament in Montreal; the event said he pulled out for personal reasons.
In women’s action, top-seeded Angelique Kerber defeated 2009 U.S. Open quarterfinalist Melanie Oudin 7-5, 6-0; No. 3 Ekaterina Makarova eliminated Caroline Garcia 6-2, 6-0; and No. 5 Sorana Cirstea got past Alison Riske of the U.S., 3-6, 6-2, 6-3.
