The blazing opener made light work of South Eastern's handy total of 173 at Jack Brabham on day two of the Western NSW Junior Cricket under 15s carnival.

An equally damaging knock of 71 off 65 balls from Dylan Melvey lifted South Eastern after they were in trouble at 5-57 but Kreuzberger's heroics stole the show in a nine-wicket victory for Mitchell.

He whacked 21 boundaries and batted for over two-and-a-half hours to carry his bat throughout a memorable innings.

It's the host's first win of the tournament, after a fairly hefty 103-run loss to the Wakatipu High School side on Monday.

The New Zealand boys were back at it on Tuesday, too, key batsman CJ Kemp guiding Wakatipu home with a half ton in his team's pursuit of Northern District's all-out total of 102.

The kiwi gun proved unstoppable as his side ran down the total at better than a run a ball, coasting to 1-108 two balls into the 17th over.

Isaac Craddock's lone-hand of 37, off just 29 balls, proved a rare bright spot in an otherwise tough day for the Northern Districts boys.

That knock will be on Craddock remembers, too, coming against an international side, while Dubbo star Lachlan Rummans also saved his best for an international opponent.

The young all-rounder was immense against the touring St John's India side in the second round, taking 4-8 with the ball to help bowl out their opponents for just 86 from 43.1 overs before guiding Dubbo home with an unbeaten 39 off 62 balls at the Country Club Oval.

Charan Madala top scored with 20 for the touring Indian side entering the crease at second drop. It was Dubbo's second win, and places them in line to appear in Thursday's final.

They take on Blacktown in Wednesday's third round in what shapes as a mini semi-final, the unbeaten western Sydney side notching up its second win in as many games, too.

After setting a total near 300 on day one, Blacktown showed it's equally impressive chasing via a six-wicket victory over Penrith at Riawena Oval.

Forty-nine at the top of the order from Rohan Joshi and then a not out 46 from Eli Sumares in the middle-order ensured their side maintained their unbeaten run heading into the final round.

Meanwhile, Mosman enjoyed a six-wicket win over Wagga on the back of Axel Bailey's run-a-ball 36 and Elliot Evans' eventful two over spell that netted 4-3.

Gordon and Western Blue fought out a thriller at Kinross on Tuesday, the second round of the Western NSW Junior Cricket under 15s girls' carnival.

Gordon batted through its 40 overs to post 6-146, Taara Kotibhaskar anchoring the innings with 40.

Every Western player had a bowl, but it was skipper Hanna Knight who proved the most effective, taking 3-7 to help limit the total her Blue side was going to chase.

Western opener Montana Griffith played beautifully at the top of the order, hitting 39 but when she fell with the score on 83 the hosts lost regular wickets.

A rear-guard seventh-wicket partnership of 34 between Maddison Spence (26 not out, off 18) and Knight (15) nearly got their side home but Western ultimately was bowled out 12 runs shy of a result.

In other games, Western Red was bowled out for 33, Vaishnavi Deobhankar (3-5) and Isabelle Cruickshank (3-7) both starring in dominating spells with the ball.

The Parramatta girls dropped three wickets in the chase but still managed a relatively simple win, while Mia Nel (68) guided Manly Warringah to another big win, this time over Penrith.

In day three action, Penrith takes on Western Blue, Western Red plays Manly Warringah and Gordon will face Parramatta.

In the under 15s boys' third round, Northern District plays South Eastern, St John's India faces Mosman, Dubbo and Blacktown will go head-to-head, the in-form Mitchell plays Wagga and Wakatipu High School will play Penrith.
