MIAMI, March 25 (UPI) -- Novak Djokovic stayed perfect for 2011 Friday, moving into the second round of the Sony Ericsson Open with a 6-0, 6-1 crushing of Denis Istomin.
The match required less than 40 minutes to complete and resulted in Djokovic's 19th victory in as many contests this year. His latest tournament triumph came last week at Indian Wells, where he pulled off the feat of back-to-back victories over Roger Federer and Rafael Nadal.
Djokovic is enjoying the best start to a season since Ivan Lendl opened the 1986 campaign with a 25-0 record.
Robin Soderling also advanced Friday and former champion Andy Murray was an upset victim.
Soderling, the fourth seed, rallied to defeat Ivan Dodig 3-6, 6-2, 6-4. Soderling already has three tour victories this season.
Murray, the No. 5 seed, fell to Alex Bogomolov 6-1, 7-5. It was Murray's fourth straight match loss.
In another surprise, Pablo Andujar eliminated ninth-seeded Fernando Verdasco 3-6, 7-6 (7-3), 6-4.
Mardy Fish was a 6-4, 6-3 winner over Julien Benneteau and James Blake outlasted Thomaz Bellucci 2-6, 6-4, 7-6 (8-6).
