The Bradford Evening League starts tomorrow with a new-look format of two divisions.
Division One now contains eight teams, who will play each other twice during the season.
But Thornton will be hoping to repeat their 2010 success of the league title and Les Benson play-off trophy.
Both teams can expect strong challenges from Salem Athletic and Shelf, while promoted Smart Moves will also be capable of causing problems with their powerful batting line-up.
The 12-team Division Two welcomes new team Buttershaw St Paul’s, who begin their campaign at home to Cambing.
