No. 3-ranked Alexander Zverev was sympathetic for Joel Schwaerzler after hammering the 18-year-old wild card in his hometown debut at the Erste Bank Open on Monday. Zverev won by a quick 6-2, 6-2 then gave 347th-ranked Schwaerzler, appearing in his second ATP tour-level match, encouragement when they met at the net. “When you come to your home tournament and probably the biggest crowd you have played in front of, as an 18-year-old and you’re playing the world No. 3, it’s not the easiest thing in the world,” Zverev said.
