Japan’s Kei Nishikori staged a 3-6, 7-5, 6-4 fightback over Alex Michelsen on Tuesday to earn his first victory at an ATP Masters match in three years. The 2014 US Open runner-up, who has been plagued in recent seasons by injury, turned the tide at the Montreal Masters as he put out the 55th-ranked American teenager who played last month’s Newport grass final. The tournament lost another big name Tuesday when Canadian Milos Raonic withdrew an hour before his opening match with a shoulder injury. The US Open tuneup event is already missing Olympic champion Novak Djokovic and silver medalist Carlos Alcaraz, who both withdrew. Nishikori, aged 34 and ranked 576, earned a second-round match with eighth seed Stefanos Tsitsipas, a former Grand Slam finalist like his Asian opponent.
