Bendigo finished the qualifying rounds as the only undefeated team and will face Sale-Maffra in Friday's grand final at The Albert Ground.

"The boys have been focused all week and they've continued to learn all week,'' Bendigo coach Matt Pinniger said.

"There's been various things we needed to improve on and we played our best game today.

"The best part is the boys have given themselves a chance to win it. That's all you can ask."

A second-straight century from Bendigo United star Ben Gunn and a milestone for Kangaroo Flat veteran Adam Burns were the highlights of Bendigo's win over Mornington.

After making 107 in Wednesday's win over Bairnsdale, Gunn produced an even better knock on Thursday.

Gunn smashed 126 off 110 balls, including 12 fours and two sixes, to lead Bendigo to 8-280 off 50 overs.

Gunn and teenager Brayden Stepien added 131 for the first wicket, with Stepien's 63 off 79 balls his third half-century for the carnival.

Cam Taylor (23) and Adam Ward (28) chipped in with the bat as well.

Mornington opener Shaun Foster threatened to destroy the Bendigo bowling attack, but once he fell for 43 off 40 balls the innings lost its momentum.

Burns took the first three wickets of the innings, with the third scalp his 100th career MCW wicket.

"It's an amazing achievement. It says a lot about his longevity, his commitment to Bendigo cricket and representing our league,'' Pinniger said of Burns.

"He prepares well, he is professional about everything he does and it's a huge reward for him. He thoroughly deserves it."

Mornington was eventually dismissed for 179. Burns claimed 3-29 off his 10 overs, while leg-spinner Cam Taylor took 3-28. Liam Smith bowled with great control, taking 1-18 off 10 overs.

Thursday's final round was marred by the Geelong versus Murray Valley game being declared a draw without a ball being bowled.

Both teams went into day four with a chance of making the final, but when they arrived at Sunshine on Thursday morning the pitch and outfield had not been prepared.

There was no other venue in Melbourne available. Geelong offered North Geelong Oval as an option, but it was declined by the umpires and Murray Valley and the game was declared a draw.

Defending champion Geelong was second on the ladder going into the final round and was hardest hit by the draw.
