Orange Public School contesting NSW PSSA Cricket Knockout final four

After OPS' netball side reigned supreme and the rugby union outfit finished second the blue and gold first XI are primed for Tuesday's final four gala day at Raby, and gunning to bring another state championship home.

They'll face Narooma Public in Tuesday morning's semi-final and should they win will face either Kingscliff or New Lambton in the decider that afternoon, after being dominant through the tournament's opening seven rounds.

"The last time we made it this far was back in 2015 so it's really great for the boys to be back in the top four," OPS coach Deb Smith said, she's been assisted this year by Mike and Stu Middleton.

"The netball side obviously won and the rugby union finished so close, the boys' touch football side made the final eight as well, so it'd be really exciting to be able to bring another state championship back.

"It's not something OPS has done in my time here, so we'll have to see how we go."

Smith said her troops shouldn't be looking to change much in Tuesday's encounters, which are 25 overs-a-side, but did suggest they'll need to be mindful of a challenging switch from true, bouncy synthetic wickets to the sometimes unpredictable turf pitches.

"I think that's the only real change we'll encounter, but in saying that I think it'll be the same for all four schools in the semi-finals because at this age not many sides or players are consistently playing on turf," Smith said.

"In fact even in their usual, weekly cricket it's probably only the representative players who play on turf, and we do have a few of those so that's a benefit for us I think, but even then it'll take a really good team effort."

Tom Blowes and Toby Middleton are two of those guns used to playing on turf, Smith said she'll look to the pair and fellow headliner Dan Ritchie to lead from the front.

All three starred with the ball in OPS' quarter-final win over Cherrybrook last week, the trio snaring two wickets apiece to help restrict their rivals to 6-99 at Lithgow - the two sides met halfway to alleviate travel issues.

Blowes banged out a well-made 30 from the top of the order as well, while Middleton finished 10 not out as he helped Zac Owens (37 not out) guide OPS home with eight wickets and 13 overs to spare.

"Tom, Toby and Dan I think will be doing the captaincy-style work on the field because if anything needs to change it's obviously up to the boys to recognise that and make those changes, but they're all good leaders," Smith said.

"They've all done well so far but they've had great support from the rest of the side who all have a big role to play and need to take control if they have to, like Zac did in [the quarter-final].

"All the boys are really excited and I don't think they'll be nervous, we'll just have to see how we go."
