Following a two-month hiatus the senior tennis returned last night, with the arrival of the first four-person teams doubles competition of 2018.
Narrabri Tennis head coach and tournament director Shane Murphy said that there had been an increase in numbers this competition, which has seen an extra team placed into B-grade.
Five teams will contest the second grade competition, while four will challenge for the A-grade teams title.
Like previous seasons, the format stayed the same.
Each team fields four players, and each are given a ranking from one to four.
Each player contests one set with each of their teammates.
At the completion of the night six sets will be played between opponents.
The winner is the team which wins the highest number of games across those six sets.
Two A-grade matches were played last night to kick off the new season.
Defending champs Britto's Engineering took on Perfectly Measured Shots.
Britto's Engineering, which featured Wee Waa trio Dean Holland, Anthony Gray and Rob Britten, as well as Narrabri Tennis coach Matt Nash, began its title defence with a 27-23 win.
Perfectly Measured Shots included Marcel Walsh, Scott Castlemain, Stacey Etheridge and Richard Baranski.
In the other A-grade match Nick Beerios downed Team Warwick 18-8.
Nick Beerios only fielded three players - Nick Smart, Shane Murphy and Blake Jarrett - so only three sets were played.
Team Warwick included Warwick Moppett, Travis Heffernan and Allyce and Brock Heideman.
