The Winkworth Cup, the Twenty/20 competition for Lincs Premier Division Clubs, starts on Bank Holiday Monday (May 4, 10.30am).
Bourne, Spalding and Market Deeping play a round robin tournament at the Abbey Lawns with the winners progressing to Finals Day later in the summer.
Spalding reached Finals Day last season, but lost in the semi-finals.
Reigning Premier Division champions Bourne won the competition in 2013 and will start favourites on Monday with home advantage.
The three local clubs also play each other in the revamped Jaidka Cup, a Twenty/20 competition that starts on May 13.
