|Fast-paced and thrilling: badminton in short form|
|NBL games are played to a first to nine points rally scoring system. In each of the five events which are played to best-of-five games in a regular match-night fixture - the first four games are played to first to nine with no extended scoring or need for a clear winning margin.|
Having overcome University of Nottingham Sport 3-2 in the semi-finals, Team Derby faced Loughborough, who beat pre-tournament favourites Surrey Smashers 5-0 in the other semi-final.
With the scores at 2-2, the UK's first badminton league ended in dramatic style.
The Championship was decided by the final event of the day, the women's singles, which saw Zetchiri take on Schnaase, the Bulgarian and German number one ranked women respectively, with Derby's Schnaase running out a 3-0 winner.
