Four-time Key Biscayne runner-up Rafael Nadal advanced to the men’s semifinals by beating American Jack Sock 6-2, 6-3 on Wednesday.
Nadal’s opponent Friday will be Fabio Fognini, who became the first unseeded player in 10 years to reach the men’s semis at Key Biscayne when he beat 2016 runner-up Kei Nishikori 6-4, 6-2.
Nadal is playing Key Biscayne for the 13th time, making it his longest title drought at any tournament. He committed only 12 unforced errors against the No. 13-seeded Sock, rallied from a break down in the second set and improved his lifetime record against Americans to 60-9.
