Federer never made excuses for defeats, he would look sour maybe but never make excuses. He even scolded Mary Carillo when she said that Roger tanked the cinci match vs Murray in 2006, even though Federer did do that but he did not say that in public, he took offense at the fact that someone decided to call him out for that....
Fed has made excuses for defeats many times.
For example, Fed claimed 8 years after losing to Rafa at the 2004 Miami Masters that he lost due to a sunstroke from Indian Wells.
TennisNow, 23 March 2012:
¤¤ Since the tour is in Miami this week and next, we figured, what better time to look at a very historical moment that occurred in Miami, some eight years ago. /---/
Federer spoke a bit about the historical affair yesterday during a press conference in Miami. /---/ (The score was 6-3, 6-3 in favor of Nadal.)
“
I came with a sunstroke from Indian Wells, fine,” said Federer of his first close encounter with a player of the Rafa kind, “but I was starting to feel better and I was like didn't quite understand what just quite happened.” ¤¤
