GSTAAD, Switzerland - Thomaz Bellucci beat Andreas Beck 6-4, 7-6 (2) in the Swiss Open final on Sunday to claim his first ATP Tour title.
The 21-year-old Brazilian used the only break of the match to win the first set and then prevailed following a 60-minute rain delay in the second.
The 119th-ranked Bellucci became the fifth first-time winner on tour this season, though not the lowest-ranked.
Rajeev Ram of the United States was No. 181 when he won the grass-court tournament at Newport, Rhode Island, earlier this month.
Bellucci, who had to qualify for the clay-court tournament, broke his 51st-ranked German opponent in the opening game, and sealed the first set when the 23-year-old Beck netted a forehand.
The second set went with serve before a heavy shower forced the players off with Beck leading 4-3.
When play was resumed, Bellucci saved the only break point he faced in the match with a two-handed backhand winner.
Beck saved two break points at 5-5 but could not hold off Bellucci in the tiebreaker, sending a sliced backhand long on the Brazilian's first match point after one hour 41 minutes.
