Rio de Janeiro - Chilean third seed Cristian Garin stretched his win streak to nine matches on Sunday by beating Croatian fifth seed Borna Coric 6-4, 7-5 to reach the Rio Open final.

Garin, coming off a title two weeks ago at Cordoba, will play for the Rio crown later on Sunday against Italian qualifier Gianluca Mager, who ousted Hungarian lucky loser Attila Balazs 7-6 (7/4), 4-6, 7-6 (7/2).

Giant-killer Mager upset Australian Open runner-up and 2017 Rio champion Dominic Thiem, the world No 4 from Austria, in the quarter-finals.
