Milos Raonic’s hopes of a maiden grand slam title were brought to a grinding halt by Ryan Harrison on Wednesday.
The fifth seed was tipped for a deep run at Flushing Meadows after making his first grand slam final at Wimbledon in July.
However, while the hard courts of New York should have suited the Canadian, an error-strewn performance which was hampered by cramps saw Raonic fall to a 6-7 (4), 7-5, 7-5, 6-1 defeat.
Raonic’s typically dangerous serve produced 18 aces, but he also stumbled to 15 double faults and made 62 unforced errors, providing Harrison with plenty of chances. The American duly obliged, converting seven of the 18 break point chances that came his way.
The win sends Harrison into the third round of a grand slam for the first time.
“It’s a big win for me,” said Harrison, who will face Marcos Baghdatis of Cyprus in the next round. “Milos is a really great player and he played fantastic at Wimbledon.”
