Qualifier Mona Barthel of Germany rallied to win the Prague Open Saturday, beating unseeded Kristyna Pliskova of the Czech Republic 2-6, 7-5, 6-2. Barthel broke Pliskova for a 4-2 lead in the final set before converting her second match point for her fourth WTA title and the first since 2014. "I can't believe it," Barthel said. "Somehow, I made it. I'm completely exhausted." The 82nd-ranked Barthel saved three match points in the second round of qualifying on her way to victory in the final. Barthel dropped her serve Saturday to go 3-4 down in the second set but she got a break back in the following game. The German wasted a set point at 5-4 but converted her second set point to take the set 7-5. Barthel improved her record against the 58th-ranked Czech to 2-1. "I'm sorry I didn't make it," said Pliskova who was seeking her second WTA title. Zverev targets home title Germany's rising star Alexander Zverev will face Argentina's Guido Pella in Sunday's final of Munich's ATP clay-court tournament as the 20-year-old bids for his first title on home soil. Hamburg-born Zverev has a shot at his third ATP title after beating second seed Spaniard Roberto Bautista Agut, a clay-court specialist, 7-5, 7-5 in Saturday's semifinal. He fired down an ace to convert his first match point after one hour, 33 minutes in the Bavarian capital. "I played well," said Zverev, who was cheered by the Munich crowd. "I am happy to be in the final, it will be something special, because it is in Munich. "Winning in Germany would be something amazing, something that I've dreamed about. But it's going to be a very tough match and I've got to stay focused." Pella, 26, ranked 158th in the world, booked his final berth with a 4-6, 7-5, 6-4 win over South Korea's Hyeon Chung, 20, who had knocked out top seed Gael Monfils in the second round. The 1.98m (six foot, six inches) Zverev, ranked 20th in the world, is on the rise after winning in St Petersburg last September and Montpellier in February. — Agencies
