This season's Alan Scott Wines Summer League bowls competition is set for an exciting climax at the Riverside Bowling Club on Saturday.

It's grand finals day of the league, the brainchild of Riverside Makos player Ken Hart, and it's the sixth year of the popular competition.

Played on a Wednesday night in October/November, the competition features the top players in the province playing singles, pairs, triples and fours. There are five players in each team and positions in the respective disciplines are changed each week to provide variety for the players. On one week, singles and fours are played and the next, triples and pairs.

Last week's final round-robin matches showed the closeness of the competition. Riverside Makos went from second to fourth, the Renwick Roosters moved from fifth to third, pushing Blenheim's Touch a Class out of the semifinals.

In Saturday's semifinals, top qualifiers the Springlands Swans take on fourth-placed Riverside Makos while Havelock's Pelorus Jacks at two play the third-placed Renwick Roosters, the two winners meeting in the afternoon final.
