THIRTY-SIX teams remain in the Central Wimmera Tennis Association junior competition after the semi-finals at the weekend.
There were several notable upsets, including Horsham Lawn Black beating Laharum in 17 and under A Grade boys competition.
Laharum had set the pace for much of the season, finishing atop the ladder as minor premier with only three losses.
The two teams had faced each other three times before Saturday's semi-final, producing two thrilling encounters and a 2-1 head-to-head advantage for Laharum.
But it was Lawn Black that controlled Saturday's match, with Hugh Gove and Ethan McRae getting the underdog off to a dream start with a 6-0 whitewash of Jayden McQueen and Pat Easson in the opening rubber.
Angus Gove and James McRae followed with a 6-5 tie-break win over Ambrose Launder and Campbell Mason, which gave Lawn Black a two-sets-to-zero advantage.
Laharum's McQueen redeemed himself in the singles with a 6-2 win over Hugh Gove, but when the rubbers were tight, Lawn Black had all the answers.
Four sets were decided by tie-breaks - all went Lawn Black's way.
Lawn Black is through to the grand final, while Laharum will face Horsham Lawn Yellow at the weekend for a grand final berth.
Lawn Yellow's Lachlan Clark was a stand-out in his side's cut-throat final win over Haven, 5-39 to 3-29.
Horsham Lawn won through to the grand final in extraordinary circumstances in the 17 and under A Grade girls competition, beating Central Park Orange in a thriller.
The scores were locked at 4-32 apiece at the end of play after an up-and-down battle that saw neither side win consecutive sets.
The tie in scores meant an extra set was played between Lawn's Kirby Knight and Caitlin McQueen, and Central Park's Gemma Morgan and Ash Davis to decide the match.
Knight and McQueen lifted their team to the grand final with a 6-1 win in the tie-breaking set.
Central Park Orange will get a shot at redemption on Saturday when it faces Central Park Purple, which annihilated Central Park Pink to advance.
Park Purple never dropped more than three games in any of its rubbers in an 8-48 to 0-10 rout.
Haven Black went straight to the 17 and under boys grand final because of a Haven Red forfeit, while Central Park kept its season alive by defeating Laharum.
In 17 and under B Grade girls competition, Natimuk was another beneficiary of a forfeit and advanced to a grand final, while Quantong made short work of Haven Lawn.
Laharum got the better of Quantong in the 14 and under A Grade boys division, with Reuben Launder's 6-4 win over Josh Freeman in the singles setting the tone.
Quantong will now play Horsham Lawn Green, which disposed of Central Park Orange in the other final.
In 14 and under A Grade girls competition, Horsham Lawn Purple kept its season alive with a thrilling four-game victory over Haven Blue.
The team will now play Quantong, which lost to Haven Red at the weekend.
