Rapira was strong during the final five rounds and when he scored his second knock down at the end of the 10th Rapira was always going to be handed the belt at the post-fight presentation.
"Tip and I were a bit glum for a while afterwards. But then Tip told me he learnt a lot and he wants to be first in the queue to fight Sam should he decide to come out of retirement. At no stage did I think Tip was out of his depth," Langdon said.
"Obviously Tip was always going to be up against it. Rapira was motivated in what was his last fight and he was in his own backyard. It was also Tip's first 10 rounder. But he should be proud of himself.
"Yes Rapira's experience showed during the later rounds. Tip made a couple of errors of judgement and got whacked ... but Rapira had to draw on all his experience,' Langdon added.
Maniapoto's next fight will be in July. It will be interesting to see the calibre of opponents chase after that assignment in the wake of Rapira's compliment.
