The Swiss 19-time grand slam winner, who still trails Nadal 23-15 in their overall head-to-head record, didn't face a break point and started and ended the match with service breaks.
"I don't know what my expectations were going in," Federer said. "I thought I might struggle early on because it was a late finish last night.
"It's not going to happen. We don't have enough years left on the tour. We ranked too good so we play each other only in finals at the moment.
