With CYMS skipper Hugh Le Lievre's day one ton and a total of 273 in the bank Centrals resumed their chase at 2-36 and in-form star Fletcher Rose signalled his intent immediately by hammering the first ball of the day for six.

But as he's done so many times before, Dhatt imposed himself with a controlled, marathon effort to ensure Centrals never genuinely swung momentum in their favour in the chase.

He ultimately finished with outrageous figures of 5-63 from 35 overs, a dozen of which were maidens, and combined beautifully with Aquinder Dhillion (3-12) as the red and black fell 61 short of victory.

Dhatt had already snared the scalp of Nick Dunlop (14) the week prior and picked up his second by clean bowling Jake Pauletto (14) early on day two.

With Dhillion picking up crucial wickets as well, including Brenton Anthony for a well-made 60, Dhatt was hypnotic at the other end as he also claimed the scalps of George Olsen (10), Zac Reimer (13) and Matt Ripps (8).

Dhatt's effort was stunning regardless of context, but the fact CYMS were without Gus Wilson and Le Lievre wasn't able to bowl either made it almost Herculean.

The wily left-armer bowled 20-odd overs unchanged first-up on Saturday before a short break, returning to bowl another dozen or so to close the game out.

"Evergreen Al Dhatt, he was amazing," Le Lievre said of his veteran tweaker.

"Amazing control, he dictated the pace of their run chase."

Despite only playing two of this summer's five games, and making one Royal Hotel Cup appearance, Dhatt has already taken 10 wickets in the reinvigorated, combined competition.

His round five bagful backed up a five-wicket performance against Bathurst City in his return clash in round four, he picked up 4-36 in the first innings of that game and then snared one more in Redbacks' second dig.

True to his miserly history, Dhatt's 10 wickets have come at just 14.6 runs apiece and he picked up one scalp in his lone Twenty20 showing as well.

Le Lievre, stoked to have such an intelligent bowler back in the ranks, went on to say how impressed he was with his entire side, considering the hot, smoky conditions at Jack Brabham 1 on Saturday afternoon.

He admitted they weren't at their best in the win but was over the moon they got the job done with their backs-to-the-wall.

"I'm super proud of the team," Le Lievre said.

"We didn't field well, it was hot and we were light-on for bowlers but we found a way to win and consolidate our top four position."

The victory has just about done that too, it's certainly pushed the green and golds further into the finals frame at the very least.

With the two Bathurst-based games being called off on Saturday morning due to the smoky conditions and confirmed as draws, CYMS have moved into a share for fourth with Centennials Bulls thanks to their round five win.

Those two sides are locked on 18 points with St Pat's Old Boys one further ahead, while Orange City and Cavaliers are another five in front.

The greens and maroons will enter the new year deadlocked at the top of the table after the latter handed the former their first defeat of the summer at Wade Park on Saturday afternoon.

After Matt Corben's second ton of the summer led Cavaliers to 238 and while Orange City looked well in control at 0-46 as day two started, the previously-undefeated competition leaders eventually rolled over for just 175.

Only Ben Schofield (57) made any real impact for Orange City as Mark Maybin (4-7), Hugh Middleton (2-21) and Mitch Black (2-65) did the damage on a hard, flat Wade Park wicket.

Black's effort was a 26-over marathon too, he continues to prove he's one of the competition's premier spinners, if not the leading man.

While St Pat's Old Boys, Rugby Union, City Colts and Bathurst City weren't able to make any impact on Saturday, or take the field at all, Kyle Aubin and Kurt Toole made sure their Centennials finished the first half of the season on a positive note.

They did the bulk of the damage with the ball as the Bulls skittled Kinross 49 short of victory at the school's Main Oval, the students finished with 124 in reply to Centennials' day one tally of 172.

Tyler Horton's strong knock of 87 led the Bulls to that score which, admittedly, looked well under-par despite being reasonably competitive.

Aubin (4-33) and Toole (3-24) made sure it was far more than competitive though, combining to take seven of Kinross' wickets and lead the Bulls' victory.
