Treat Huey, partner Max Mirnyi in Miami Open semis

TREAT Huey and partner Max Mirnyi of Belarus downed Americans John Isner and Nicholas Monroe, 6-1, 7-5, Wednesday to barge into the men’s doubles semifinals of the Miami Open at Crandon Park in Florida.

Chasing an Olympic berth, which requires a world ranking of at least No. 10, the 30-year-old Huey worked seamlessly with Mirnyi, who was his partner in capturing the Acapulco Challenger last month.

Huey and Mirnyi next face Raven Klaasen of South Africa and Rajeev Ram of the United States who downed Philipp Petzschner of Germany and Alexander Peya of Austria, 7-6 (7-5), 10-7.

Huey ranks No. 30 in the world doubles.
