Kyle Edmund defeated Dan Evans in the first all-British Challenger final for more than a decade.
British players have found success hard to come by in recent years in the very competitive second tier of men's tennis but 21-year-old Edmund has now collected four Challenger titles.
The Yorkshireman, part of Great Britain's victorious Davis Cup team in November, has begun 2016 in impressive fashion and was too strong for Evans in Dallas, winning 6-3 6-2.
The result should take Edmund past his previous career-high ranking of 88 and also puts him firmly in pole position for next month's Davis Cup tie against Japan in Evans' home city of Birmingham.
It has also been a terrific week for Evans, who qualified for the Australian Open last month and will be close to a place in the world's top 150 when the rankings are updated on Monday.
The only previous all-British Challenger final in the past 20 years came in 2005, when Alex Bogdanovic beat Mark Hilton.
