Kei Nishikori overcame early struggles with unforced errors Saturday to advance to the third round of the Miami Open with a 7-6(6), 5-7, 6-4 win over Slovenia's Aljaz Bedene.
The 39th-ranked Nishikori, who beat Bedene in straight sets at last week's Dubai Duty Free Tennis Championships, faced a much sterner challenge against the world No. 59 in Miami.
Picking up the pace in the third set, Nishikori closed out the match in 2 hours, 50 minutes to set up a third-round showdown with world No. 5 Stefanos Tsitsipas of Greece.
Former world No. 4 Nishikori entered from the second round in Miami as the 28th seed. The 31-year-old is trying to work his way back to the top 10 following an elbow operation in late 2019 that sidelined him for most of last year.
