Swiss champion Federer, however, grasps why others may not agree with Nadal. Beyond forfeiting points and prize money from Indian Wells, the reigning Australian Open champion was cleared to continue competing by the ITIA.
The news of his positive tests did not come out until the day after he won the Cincinnati Open, on August 20.
“I understand the frustration of, ‘has he been treated the same as others?’ And I think this is where it comes down to,” Federer said on the U.S. morning show Today in advance of his scheduled appearance Tuesday night at Flushing Meadows.
“The inconsistency, potentially, that he didn’t have to sit out while they were not 100% sure what was going on… I think that’s the question here that needs to be answered.”
