Rafa Nadal moved into the Miami Open semi-finals with a straight sets win over American Jack Sock on Wednesday, while second seed Kei Nishikori was sent packing after going down 6-4 6-2 to unseeded Italian Fabio Fognini.
Nadal staved off four break points to avoid going down a double-break early in the second set, a pivotal game that set the stage for his 6-2 6-3 victory on the Crandon Park hardcourt.
Nadal’s poise and shotmaking came to the fore when 13th seed Sock threatened to take a stranglehold on the second set.
“That was the key of the second set, two-love (down), 15-40,” Nadal said in a court side interview. “With three-zero a player like Jack, you’ll probably be thinking third set.
“It was a double positive thing. I saved that game and got the break back (in the next game). The match was much closer than the result says.”
Nadal could face his long-time nemesis Federer in the final, with the Swiss, who has a Thursday quarter-final against Tomas Berdych, on the other side of the draw.
Federer and Nadal have met twice this year, with Federer winning both times, in a memorable five-set final at the Australian Open and in a one-sided straight-sets fourth-round thumping at Indian Wells two weeks ago.
