Monaco: Serbia's Novak Djokovic earned his first Masters 1,000 win this year after defeating fellow Serbian Dusan Lajovic 6-0, 6-1 in the first round of the Monte Carlo Masters.
World No. 13 Djokovic needed just 56 minutes to beat his rival and concluded the Monday night's match without giving up a single break point of the four his opponent had, reports EFE news agency.
The 30-year-old Serbian, ninth-seed, is competing at the Monte Carlo Masters for the 12th time. He claimed the title in 2013 and 2015.
