Finishing fourth in the log and without injured England prospect Katie George, they went into the Ageas Bowl finals as firm outsiders for the title.
But, fully motivated and totally focussed, they chased down competitive totals to initially beat 2014 champions Parley and then thrash the Hampshire EDP squad by six wickets in the final.
They scored 133-4 to beat Parley with three balls to spare and had four batsmen ‘retire’ before knocking off the EDP’s 137-3 with ten balls in hand.
“To beat the two top sides in it so convincingly was a simply fantastic achievement,” beamed coach Rick Kellaway.
“I told the lads beforehand that, because they’d reached the cut-off age limit, this would be the last time they’d play together and go out and make the most of it.
“They certainly did that !”
Chasing competitive totals each time, the OTs youngsters kept their heads, pushing the ball into the gaps to comfortably score at ten runs an over throughout.
Openers Harry Tulk and Elliott Mitchell-Lee both retired before skipper Sam Costley played his part in a two-wicket win over Parley.
The same three, plus Tom George, played identical batting roles in the final, while spinner Nicho Newman showed his potential withcthe ball.
