Lithgow Thistle and Lithgow City Rangers locked in their place in this Sunday’s grand final after defeating their opponents in last weekend’s semi-finals.

The Thistle club were pushed to the limit by Collegians with the contest being decided on penalties after the two sides could not be split after 110 minutes of passionate soccer.

Scores were locked at 1-1 after extra time and Thistle keeper Thomas Stapleton rose to the occasion saving two spot kicks from Collegians, securing a 4-2 on penalties.

Nic Tomazin had given Thistle the lead early on with a strike from just outside the box however their opponents hit back in a matter of minutes.

The rest of the match was a nail-biting affair however neither side could find a winner.

Lithgow City Rangers have been the strongest side in third grade all year and they proved their credentials once again with a 1-0 semi-final win over Macquarie United.

Chris Minner hammered home the only goal after receiving a pinpoint cross from David Gausden.

Most of the 2017 season has been smooth sailing for the Rangers side with only one loss and two draws. 

"Performance-wise, this has been our best season for the last couple of years," Rangers manager Paul Goodwin said. 

"The credit goes to the players, they've banded together in a challenging season. It's also due to the efforts of the coaching staff.”

Coach Wayne Bilby has taken control of the side this season with assistance from Nigel Lloyd for the finals run. 

"We've met the Thistles twice this season and both times, we've beaten them," Goodwin said. 

"That means they'll be hungry for a win."

For the first time in many years, Rangers fielded two teams in the Bathurst competition. Fourth grade was knocked out in the semis. 

"To have both teams make the semi-finals was the best result the club's had in ten years."

A passionate crowd of Lithgow supporters were expected to make the journey across to Proctor Park in Bathurst on Sunday.

Kick off will be at 11am.
