MADRID -- Jannik Sinner wants better scheduling of matches at the Madrid Open, saying the night session "messes up the whole day" for players.
Sinner had a morning start on Tuesday and defeated Cameron Norrie 6-2, 7-5 to earn his 20th straight win on tour and reach the quarterfinals of the ATP-WTA event in the Spanish capital.
The world No. 1 said he was OK playing at whatever time he was scheduled, but the late matches -- some of which have finished past 1 a.m. local time -- were "not easy" on the players' "body and mind."
