Novak Djokovic added yet another record to his lengthy list, breaking a tie with Roger Federer for the most Grand Slam matches played in tennis history by reaching 430 on Wednesday at the Australian Open in what was a tougher-than-expected second-round victory. Djokovic improved to 379-51 for his career at major tournaments, a .881 winning percentage, by defeating 21-year-old Portuguese qualifier Jaime Faria 6-1, 6-7 (4), 6-3, 6-2 in a match briefly interrupted by light rain before Rod Laver Arena’s retractable roof was shut.
