Zverev's difficult day
However, he also committed 73 unforced errors on a blustery day in the French capital. "John is a tough player who beat Federer so I knew it would be difficult today," said Zverev, bidding to become the first German man to win the Roland Garros title since Henner Henkel in 1937.  Next up for Zverev is Swedish qualifier Mikael Ymer, the World No. 148 of Ethiopian origin, who marked his Grand Slam debut with a 6-0, 6-3, 7-6 (7/5) win over Slovenia's Blaz Rola.
