Madison Keys returned to the scene of her 2019 Charleston WTA triumph on Thursday with a hard-fought win over Carline Dolehide in the Credit One Bank Invitational. The 16-player team event, staged with strict social distancing protocols as players prep for the return of WTA action in August after a coronavirus shutdown, is a far cry from the full-fledged WTA Tournament on the green clay courts in South Carolina. But Keys, ranked 13th in the world, admitted she was nervous in her first match since a third-round exit at the Australian Open in January. Those butterflies showed as she let a 3-0 second-set lead slip before pulling off a 6-1, 6-7 (6/8), 10-4 victory over 134th-ranked Caroline Dolehide. Keys finally fired a forehand winner up the line on her fourth match point to claim the match, scoring a point for her Team Kindness, which is going up against Team Peace captained by Bethanie Mattek-Sands. "That was up and down," Keys said after tapping racquets with Dolehide at the net. "That was -- I haven't played a match in a really long time. "I was definitely really nervous, and that obviously showed. But I was really happy to get a win and a point for my team. "All in all, things to work on, but not too bad for a first match." Keys is one of three top-10 players taking part in the tournament, along fourth-ranked Australian Open champion Sofia Kenin, and No. 19 Alison Riske. bb/caw/
