KEY BISCAYNE, Fla. (AP) Novak Djokovic won a record-tying sixth Key Biscayne title and his third in a row Sunday, beating Kei Nishikori 6-3, 6-3 in the Miami Open final.
The top-ranked Djokovic improved to 28-1 this year. His only loss came when he retired during his quarterfinal against Feliciano Lopez in Dubai with an eye infection.
Djokovic won his 28th ATP Masters title, breaking the record he shared with Rafael Nadal, and won both Indian Wells and the Miami Open for the third year in a row. He tied Andre Agassi's record of six men's titles at Key Biscayne.
Nishikori lost to Djokovic for the sixth consecutive time and was doomed by an erratic serve. He double-faulted five times, and Djokovic repeatedly pounced on his second serve to break five times.
