The team is within three wickets from victory.

The Wests, trailing United by 87 runs, looked to be in serious trouble in the second innings when Ryan Main and Amardeep Saran were out after making two runs each.

Things turned worse when Josh Bamford, Colin Weller, William Phillips and skipper Matthew Shiell followed suit and the team slumped to 6-48.

With the Wests seemingly dead in the water, 20-year-old Ashleigh Peters stepped up and hit a remarkable 120 to kickstart his side's revival. The team finished on 237, with 16-year-old Corey Irving contributing 51.

Wests' Chris Irving put on a masterful performance with the ball, claiming 5-18, as the side contained United to just 7-49.

Wests' coach Paul McGowan was in high spirits.

"To be honest I thought the match would be over after a couple of hours," he said.

"We were dead and buried at one stage and I was impressed by the courage of our players to keep fighting."

McGowan was even more impressed by the performances by some of his less experienced players who stepped up when the chips were down.

"What Ashleigh Peters and Corey Irving did was unbelievable and Ash's 100 has to be the best 100 I've ever seen," he said.

"I copped a lot of flak for selecting him but our faith in him to produce in big games really paid off."

But McGowan said his team still had much work to do before it could be crowned champions.

"They still have ex-captain Dean Comensoli left to bat as well as Jeremy Preston and both are hard men to get out," he said.

"But the boys are pumped and know they have a chance to win."
