Recently returned from training in Thailand, Heaps could hardly utilise any of the kicks or knees from the clinch he may have developed as the Wanganui fighter muscled him into the ropes and corners, pounding away non-stop.
Alderton may have lacked finesse but certainly not stamina as he kept the pummelling up for every moment of the three rounds.
It was not such a happy homecoming for Kazuki Campbell, as Masterton's Zane Hopman caught him with a brutal knee to the head early in their bout.
Jess Johnston had his moments against the heavy-hitting Oscar Remihana, but the big Taranaki fighter was the clear winner from their three-round affair.
MMA
Wanganui's Mixed Martial Arts exponents had no interest in finding out what the judges thought, finishing their men inside the distance.
Matt Gibson's judo skills shone through against Palmerston North's Rian Rees, whipping him off his feet and looking to unload with the ground and pound blows.
Rees's best chances came early in the first and third rounds when he briefly got the mount position, only for Gibson to calmly free himself and counterattack.
Trapping Rees near the ropes with nowhere to go, the Wanganui fighter secured the arm and forced the tap out.
At an imposing 102.3kg, the big and popular Kamipeli Latu went to war with New Plymouth's Logan Skelton in a two-round slug fest.
Up for the challenge, Skelton covered up and absorbed most of the Border rugby player's best blows in the early exchanges, taking him down with a head lock and nearly trapping both arms.
But by round two the tank had reached empty and even though Latu was likewise swaying on his feet, he still had that knockout power - a straight shot buckled Skelton before a series of knees doubled him over.
Ring Karate
Wanganui experienced mixed results in the Ring Karate match-ups. Chris Sheahon controlled the tempo in the early exchanges against Waitakere's Siva Faalavaau, who came back in the last round with a series of blows to the midriff.
Both men had to settle for a draw.
Ryan Trevor-Roper's workrate and determination saw him win out over Palmerston North's Bernie Johnstone.
Willing to take punishment to get inside and do damage, Trevor-Roper kept up his hustle to earn favour on the scorecards.
