The Bay are cup holders in the Central Districts inter-district tourney, which is the symbol of one-day supremacy, before they embark on the two-day Hawke Cup campaign from next month.
The Chapple Cup also offers CD selectors the opportunity to make final selections on borderline players.
Senarathne took part in a two-day CD Stags trials this week but admittedly came up shy.
"I didn't have a good trials but I learned a lot of new stuff. It was great two days with the best players from CD."
He is happy to play Chapple Cup but isn't sure how the Hawke Cup will pan out because of NTOB commitments.
"Dougie Bracewell invited me to play here and his father, Brendon, looked after me [at the academy] so it will be great to play alongside Dougie in the Bay team this weekend."
Senarathne met Bracewell in England in 2009, before accepting to play for The Station Napier Old Boys' Marist, who the Bracewells were involved with then.
He lauds the province for its conviviality, standard of cricket and the prowess of head groundsman Phil Stoyanoff in producing fine wickets.
"[HBCA CEO] Craig Findlay's management of cricket is good and he also gave me junior coaching," says Senarathne, who also mentors Lindisfarne College pupils and hails the contribution of Dale Smidt in developing Bay junior reps.
He is indebted to Dan Hart and his family for giving him lodging during summer, mindful such factors contribute to better performances.
This summer he has dropped to No4 for NTOB and last Saturday, in the opening round of the Property Brokers two-day English-style 55-over competition, racked up an unbeaten 144 runs from 105 balls, including 13 boundaries and eight sixes.
His portfolio this weekend for the Bay, he believes, is to see the game to the end in helping out juniors.
"Skippy [Sinclair] has scored 15,000 first-class runs in 20 years of experience, so it's a good opportunity for me to learn from a guy like him to improve my game."
In Vancouver, he relished playing against IPL squad members from India and Windies.
Voted the British Columbia player of the year the previous northern summer, Senarathne enjoyed having the services of Bay of Plenty cricketer Scot Stewart.
"You improve your game there because there's a lot of good spinners," he says, leaving an indelible impression on the league president, Rod Hesp, who will travel with Vancouver CC president Alex Turko and club secretary Ingrid Kendrick to watch him play in the Bay in December/January.
"Rod gave me a job there as a gardener and painter," says the right-arm offspinner who has amassed 1400 runs in two seasons there.
The former Kingswood College pupil, who greeted Lindisfarne XI on tour of Sri Lanka in September last year to his hometown of Kandy, felt at home in Vancouver.
"I'm grateful to my aunty [Geena Amath] for letting me stay with her and there are lots of Sri Lankans there, so it was just like being at home."
Senarathne is confident Sinclair has picked the right team to retain the Chapple Cup this weekend, although sporadic rain may see the dreaded Duckworth-Lewis Method kick in to decide outcomes.
