Serena Williams

One match defines Williams's 2026 ledger, and it went the wrong way: a 0-1 record built entirely on a Round of 128 loss at Wimbledon, unranked and with no lead-in results to lean on. She took the second set on a tiebreak before the match slipped away in a deciding third, dropping the first and third 6-3 to a much younger Maya Joint. For a player with no other 2026 data on the board, the takeaway is the deciding-set margin — the middle set proved she could hang, the bookends showed she couldn't sustain it across three.
