Each day of the tournament, we'll preview and predict three must-see matches at Wimbledon.
What am I doing highlighting a match between two guys ranked No. 32 and No. 589? Delpo and Gulbis are two of the most under-ranked players on tour; the Argentine was playing Top 5 tennis at the end of 2016, and Gulbis, who was in the Top 10 once upon a time, calls his current position on the totem pole a “disaster.” Del Potro has been injured, and Gulbis has hardly won a match of late, but if you like heavy artillery, and players who aren’t afraid to use it, this should be the most entertaining slugfest of the second round. Del Potro leads their head to head 3-2, but Gulbis won their last meeting, indoors, in 2014.
Winner: Del Potro
Alexander Zverev vs. Frances Tiafoe
Would you be happy if you never heard the term NextGen again? If so, you might not be too pleased during this second-rounder between the 20-year-old German and the 19-year-old American. This is a preview, potentially, of later-round battles in the years ahead. We know Zverev will be there, and this year the No. 64th-ranked Tiafoe has started to show what he can do when he’s at his best. But Tiafoe didn’t have one of those days in his only previous meeting with Zverev; the German beat him in three routine sets at the Australian Open this year. But Tiafoe has improved since then, while Zverev hasn’t yet shown that he can raise his level at the Slams.
Kerber survived her opener against No. 247-ranked Irina Falconi, but it was hardly a convincing performance. Now the No. 1 seed gets Flipkens, a former Wimbledon semifinalist whose slice-based style is designed to throw baseliners like the German off their games. Their only meeting came at Wimbledon in 2014, where Kerber won in three sets.
