Becker is the first qualifier to win an ATP Tour title in 2009
Germany's Benjamin Becker lifted the first ATP Tour trophy of his career on Sunday after a 7-5 6-3 win over Raemon Sluiter at the Ordina Open.
Sluiter, who recently came out of retirement, was the lowest-ranked player - at 866th - to reach an ATP final but could not match Becker.
"I really played well," said the 28-year-old qualifier.
Tamarine Tanasugarn defended her title in the women's event, beating Belgian teenager Yanina Wickmayer 6-3 7-5.
"I must say I really feel at home here," said the 32-year-old Thai, who defeated world number one Dinara Safina in the semi-finals.
