Nine first-round retirements ties Australian Open record
MELBOURNE, Australia (AP) -- The nine first-round retirements at the Australian Open -- eight men and one woman -- equaled a record for the most retirements or walkovers in a single round at any Grand Slam in the Open Era.
As the heat wave continued at Melbourne Park on Wednesday, 32nd-seeded Ivan Dodig became the 10th player to withdraw from the tournament. He retired due to cramping while trailing Bosnian qualifier Damir Dzumhur 4-6, 4-6, 6-3, 4-1.
Tournament officials said the nine retirements in the first round matched the record set in the first round at the 2011 U.S. Open and the second round at the 2013 Wimbledon. The U.S. Open in 2011 holds the record for most overall number of retirements with 17.
The first-round retirements at Melbourne Park included Bernard Tomic's left groin injury which forced him to quit his match with top-seeded Rafael Nadal after losing the first set Tuesday.
Among others, Tommy Haas and Alex Bogomolov Jr., had shoulder injuries and John Isner retired with a right ankle injury.
