"But I was only one knock away from making a difference," says Sinclair who has 36 first-class centuries to his credit for the 2012-13 Plunket Shield champions.
The former Black Cap, though, is resigned to taking the uppercut on the chin that players who don't perform will inevitably get the chop in a "very cutthroat environment".
"I feel a little bit aggrieved although I wasn't performing as well as I could have, let alone to my standards."
Effectively the 2012-13 Plunket Shield champions have had a lackadaisical start to their limited-overs campaign with Sinclair accumulating about 60 runs from six games although, it seems, it all came to a head when Auckland Aces dismissed them for a paltry 74 runs in the sixth-round thumping.
CD also had a forgettable HRV Cup Twenty/20 campaign, finishing dead last with two wins from 10 to suggest the overall formula isn't right in the abbreviated format of the game, as the major association embarks on a three-year plan that sees Hunt moving on.
Consequently it is logical to assume other top-order batsmen haven't fired consistently either and begs the question if he became the scape goat for mediocrity in the stock take of the collective.
While veteran Jamie How, predominantly, and fellow opener Jeet Raval broke several records this month there's little else to cheer about.
In fairness to Sinclair, he was the third highest run scorer in the T20 competition with 382 runs this summer, behind Wellington's Jesse Ryder (584) and Otago's Ryan ten Doeschate (401) with no other CD batsman featuring in the top 10.
In the shield competition, Carl Cachopa topped the CD class with 807 runs at No 5 while Raval came in at No 7 with 750.
How is CD's top dog with 318 runs in the Ford Trophy competition at No 5 with Michael Papps setting the pace at 586.
"I'm averaging around 41 in the shield, which is a little below my career average," Sinclair says.
"Any club would take that but I don't know what CD are thinking right now," he says, adding he's played for CD for almost 18 years and loved it so, consequently, that's why he has been living in Napier with his wife and two young children.
He's the first to admit that, like many domestic cricketers, his mind has wandered a little on contemplating what he'll be doing in winter.
It's been a tough summer with players away from home for lengthy spells so that didn't help their cause.
"I had Barney [Kieran Noema-Barnett] coming to me and saying things and, you know, I had my share of that in New Zealand cricket and, you know, I don't need that sort of thing all over again."
Sinclair has done a stint with the Napier City Council as the roving ambassador of Business Hawke's Bay and enjoyed it but is waiting to hear from them this year.
With Hunt having "clocked off", he's keen to see what developments are in store in the appointment of the new CD coach and if the association still have him in their equation with CEO Hugh Henderson proposing a three-year plan that'll no doubt champion the young.
Whether Sinclair will contemplate sitting a few university degree management papers extramurally or start putting his feelers out for a stint with another major association remains to be seen.
"I still feel young and believe I have a lot to offer but CD is a tough association to play for."
For the record, he feels William Young, his replacement in tomorrow's final game against the Canterbury Wizards in Christchurch, is a talented young man and deserves his break after returning from injury.
Any chance Sinclair had of proving he's still in good nick with the bat at premier men's club level was dashed with bottom dwellers NOBM failing to make the playoffs.
