The men in red claimed their eighth Whitney Cup in 11 seasons on Sunday with a comprehensive 166-run win over Newtown in the 2014-15 decider.

"Missing out last year really did hurt but we're back where we belong now," he said.

For Newtown captain Mat Skinner, it brought to a close a season in which the Tigers announced themselves as a premiership force after years in the finals wilderness.

The Tigers set the pace early in the season and went into the Christmas break with only one loss to their name before they came out in the new year and won the McDonald's Megahit Twenty20 competition.

"Bit disappointing but at the start of the year if we were offered a spot in the grand final and a night cricket win, we would have taken it," Skinner said.

"We'll learn, we're a young team but we dropped too many catches and you can't afford that against Colts."

Early on day one the match looked to be going all Newtown's way as Colts fell to 3-41.

But after Greg Buckley, who edged early on through wicketkeeper and slip, made 54 then Jason Ryan and Tim Cox again combined to pile on the runs.

After putting on 128 together last time the two sides met, the veteran duo this time combined for an almost identical 123-run partnership to give their side day one honours.

Nathan Jones chipped in with a valuable 34 not out in no time at all late on to help Colts past 300.

"We've got the depth there, 'Coxy' came out and made 60, the way 'J R' has been batting the last few weeks has been great and he got another 80-odd and then 'Jonesy' in the last three overs made 35 or so and he was batting ten so it was brilliant," Morton said of his team's batting effort.

"They (Newtown) had the batting line-up to do it and 300 was one of those scores that if they came out and teed off they could have done it easy but they went the other way and lost early wickets which didn't help them."

Skinner admitted his side was disappointed to let Colts get away and after three wickets from Sean Mason, including two in two balls, his side was always up against it on day two.

"Three hundred was always going to be a big chase, one of the top four needed to get a big hundred and we lost two early and then I went and it put a lot of pressure on the rest," he said.

"They [Colts] played tight and as soon as they got a sniff they took full advantage."

Mason and wily Tim Cox took three wickets each while Buckley (2-36) and Nathan Jones (1-20) were the other wicket-takers.

Jarrod Toole continued his good form with the bat for Newtown and finished with a well-constructed and determined 62 not out while 15-year-old Ben Knaggs had a stellar match and scored 23 to go with his outstanding 4-49 on day one.

Skinner admitted Colts were worthy champions while Morton was overjoyed with his team's efforts as they finished their season in the perfect way.

"It's very close to a perfect season, we only lost two games and both of those were by less than about 20," he said.

"We finished on top by, I think, more than 20 points and then won the final by 150 runs, it doesn't get much better really."
