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. “Grand Slams, of course, they are the pillars of our sport. They mean everything for the history of the sport. Definitely, the most important tournaments,” Djokovic said.
