Jack Sock, a graduate of Blue Valley North High School, advanced to the final of the Stockholm Open with a grueling win over one of the rising stars of tennis.
Sock, the No. 6 seed who is playing a tournament as the top-ranked American for the first time in his career, defeated No. 4 seed Alexander Zverev 6-7 (7-4), 7-6 (7-4), 6-4 on Saturday in a match that lasted 2 hours, 48 minutes.
“We both had chances obviously at times,” Sock said. “It was a very good match, very good tennis. We both were battling out there.”
Sock will face Olympic silver medalist Juan Martin del Potro, who defeated No. 2 seed Grigor Dimitrov 6-4, 7-6 (7-2) in the semifinals, in Sunday’s championship match.
“He’s been playing great this week. … He’s serving well and hitting big forehands,” Sock said. “So I’m definitely going to have to try to get into his service games as best as I can, scrap some points out and then take care of my serve.”
Sunday’s appearance will mark Sock’s fifth in an ATP World Tour final. His only win came last year in Houston.
