PARIS — Novak Djokovic notched another career milestone: His young son, Stefan, watched him play, and win, at Roland Garros for the first time. The top-ranked player bidding to win his fourth consecutive major beat 104th-ranked Henri Laaksonen 6-1, 6-4, 6-3 Thursday.
Djokovic will play 147th-ranked Salvatore Caruso of Italy in the third round.
Also, Dominic Thiem overcame some trickery from Kazakh opponent Alexander Bublik to advance to the third round with a 6-3, 6-7 (6), 6-3, 7-5 victory.
Bublik surprised Thiem with an underarm serve in the first set and frustrated the Austrian with a series of drop shots, spins and volleys. But last year’s finalist at Roland Garros recovered from a break of serve in the fourth set and then gave Bublik a taste of his own medicine on his first match point, producing a well-disguised, and successful, drop shot.
Thiem will next face Pablo Cuevas, another master of trick shots. Cuevas was leading 7-6 (3), 6-3, 2-1 when Kyle Edmund retired from their match because of a left knee injury.
