Former world No. 1 Lleyton Hewitt was a first-round winner Wednesday, as the men's portion of the lucrative Sony Open got underway on Wednesday.
Former world No. 3 Nikolay Davydenko and American veteran James Blake also prevailed in their opening bouts to highlight the first day's action of this $4.169 million Masters 1000 event.
The two-time Grand Slam champion Hewitt got past Portuguese Joao Sousa 6-1, 7-6 (7-3) on the hardcourts at Crandon Park. Davydenko was taken to three sets by Italian Paolo Lorenzi before breezing in the final one to earn a 6-0, 2-6, 6-0 decision.
Blake had little trouble disposing of countryman Ryan Harrison, cruising to a 6-2, 6-2 triumph over the Louisiana native.
Meanwhile, quality Frenchman Michael Llodra handled compatriot Benoit Paire 7-6 (9-7), 6-2, capable Belgian Xavier Malisse edged out American Rajeev Ram 6-4, 6-7 (6-8), 6-4, and Austrian veteran Jurgen Melzer overcame Lithuanian Ricardas Berankis 3-6, 6-3, 7-6 (7-1) on Day 1.
