Their nearest challengers, Hoole Village Hall, saved their best performance of the season to the last with a 6-1 win over New Longton, but to no avail.
It was even closer at the top of Division Two with everything depending on the final match between the two leaders, St Anthony’s and Wilbraham.
Wilbraham secured the aggregate point by just seven points to win 4-3 and join the Catholic club at the top of the table, only to lose the title on the number of games lost.
In the Richard Smith Knockout Cup, Ashton Bowling went into the second leg of their quarter-final at Hoole with a lead of 134, only to have it overturned.
With five heavily-scoring winners, the home side eventually went through with 37 points to spare.
New Longton A and St Anthony’s had the comfortable wins expected and join Wilbraham in the semi-finals.
Semi-final draw: St Anthony’s (+220) v New Longton A (scratch), Wilbraham (+180) v Hoole Village Hall (+140).
