Stuttgart, Germany (SportsNetwork.com) - Spaniard Roberto Bautista Agut won the Mercedes Cup on Sunday, defeating Lukas Rosol 6-3, 4-6, 6-2 in the clay- court final.The third-seeded Bautista Agut converted three of his six break points en route to his second career ATP title. His maiden victory came at the Wimbledon tune-up in Den Bosch last month."Since the start of the season, I believed a lot in myself and my work. I've been playing really well, won a lot of matches and it was only a question of time before this happened," said Bautista Agut, who became the ninth player to capture multiple titles this season.Rosol swatted 13 aces and won 78 percent of the points on his first serve, but converted only 1-of-6 break points."The level was not as good as the previous rounds and it's a pity because I felt really good this week," Rosol said.The Czech was playing his first final outside of Romania. He failed to defend his lone title in Bucharest in April.
