No sooner said than done.
The last American man in the French Open, Jack Sock, will make his fourth-round Grand Slam debut after beating 18-year-old Borna Coric of Croatia 6-2, 6-1, 6-4.
After ending the match with a cross-court backhand that Coric netted, Sock soaked up the applause, but the celebration was rather muted. This was the most important singles win at a major for the 22-year-old, who was born in Nebraska, grew up in Kansas City and now is based in Florida.
Sock delivered 31 winners and saved the only break point he faced, winning 30 of 34 first-serve points on Court 2.
