Argentina register their first win at the World Cup on Saturday when they beat Tonga 28-12 in their Pool C match.
Montoya was the standout player for Argentina as he scored a hat-trick of tries all in the first half. Argentina had a brilliant first half but could not convert that in the second half of the match.
Tonga came back at them in the second half and dominated play.
At the end it was four tries to the two of Tonga that was the difference in the test.
Santiago Carreras scored the forth try of Argentina with Benjamin Urdapilleta adding four conversions.
For Tonga, Telusa Veainu scored a brace of tries and Sonatane Takulua succeeded with a conversion.
The TMO awards Tonga a try in the corner to make it 28-12, reducing the gap to 16 points with 15 minutes remaining. Could we see a dramatic #RWC2019 comeback?
