ROME: The records keep coming for Jannik Sinner. The top-ranked Sinner beat qualifier Andrea Pellegrino 6-2, 6-3 to reach the Italian Open quarterfinals on Tuesday and match Novak Djokovic’s record with a 31st consecutive Masters Series victory. Sinner hasn’t been beaten in a Masters Series event — the biggest tournaments outside the Grand Slams — since he retired with cramps in extreme heat against Tallon Griekspoor in Shanghai in October. Djokovic won 31 straight Masters matches in 2011. “If you want to be a great player you’ve got to play on all the surfaces and all the tournaments at your maximum,” Sinner said. “It’s the mind that makes the difference.” Like in his previous match, Sinner took control quickly with a break in the opening game before a packed Campo Centrale — where many fans were decked out in orange, which is Sinner’s theme color.
