MEMPHIS, Tenn. (AP) - Kei Nishikori of Japan advanced to the final of the U.S. National Indoor Championships when Australian Marinko Matosevic retired Saturday with a bone bruise in his right foot after losing the first set 6-4.
Nishikori will play either Feliciano Lopez of Spain or Denis Istomin of Uzbekistan on Sunday looking for his third career title and first since winning in Tokyo last October. No. 5 Nishikori was the only seed to advance out of the quarterfinals after he ousted top-seeded Marin Cilic of Croatia.
Matosevic led 2-0 before Nishikori broke back, and the 23-year-old player broke Matosevic again to go up 4-3. Matosevic then called for a trainer, who bandaged the ball of his right foot.
Nishikori served out and won the set in 37 minutes. Matosevic then retired.
