 Raonic's most frequent opponent, either inside or outside the Big Four, is Federer (12 matches). His first victory over Federer in the 2014 Paris Masters quarterfinal was hailed as "a career-defining win." His second victory over Federer — at the 2016 Brisbane International — was his first in a final against the Big Four. A third victory over Federer — in the 2016 Wimbledon semifinal — marked Raonic's first victory at a Grand Slam tournament against the Big Four.
