Alfie Hewett beat compatriot Gordon Reid in straight sets to become the first British singles player to win the Wheelchair Tennis Masters.
Hewett, beaten by Reid in last year's Paralympic final, won 6-3 6-2 in one hour and 18 minutes in Loughborough.
The 19-year-old trailed 3-0 in the first set, but won eight straight games to take the opener and establish a lead he would hold on to in the second.
"It was probably one of the best matches I have played," said Hewett.
"Gordon is a great competitor. I am really proud of this win.
