Tonga A have picked up their first win of the Pacific Rugby Cup after coming from behind to pip Samoa A 20-18 in Nuku'alofa on Thursday, gifting Fiji Warriors their fourth straight title with two games to spare.
The Samoans needed a bonus-point victory to keep the heat on the defending champions, but fell away having led 15-3 early in the second half.
Fiji Warriors will play Samoa A on Monday.
