Taylor Fritz made a winning start to his ATP Finals campaign on Sunday afternoon, taking out Daniil Medvedev, 6-4, 6-3, in his first round-robin match at the season-ending event. It was a milestone win for Fritz, too: his 50th of the year.

Taylor Fritz sent a message to his fans on Tuesday: Blondes may not have more fun, because less than a month after he colored his dark hair platinum, the US Open finalist has dyed his hair back to its natural color. "We're so back," the world No. 6 wrote in a post on his Instagram story showcasing his return to dark tresses.
