Argentina's Jaguares shrugged off a poor start and overcame a 21-point deficit in their Super Rugby debut to beat South Africa's Cheetahs 34-33 in a high-scoring thriller in Bloemfontein.
The Jaguares are among three new teams in the expanded southern hemisphere competition and they began the match with 10 of the 15 players who featured in Argentina's line-up in October's World Cup semi-final defeat by Australia.

The Argentine team were on the back foot when Cheetahs captain Francois Venter notched a try in the 10th minute.
That was followed by a series of disciplinary indiscretions that saw two Jaguars players sent to the sin bin.
Nicolas Sanchez was the first to be sin-binned in the 17th minute, and Martin Landajo followed a minute later - when he kneed Torsten van Jaarsveld in the head as the Cheetahs prop dived over the line, dislodging the ball.
A penalty try was awarded and Van Jaarsveld got his name on the scoresheet when the Cheetahs grabbed a third touchdown.
Tomas Lavanini was fortunate not to be sin-binned when he dived on top of William Small-Smith, after the centre claimed a fourth Cheetahs try to open a 24-3 lead.
Restored to a full compliment of players, the Jaguars rallied with tries from lineout possession for Landajo and captain Agustin Creevy - cutting the deficit to 24-17 at halftime.
Sanchez's kick then set up a third touchdown for the visitors early in the second half by flanker Rodrigo Baez.
Flyhalf Fred Zeilinga slotted two penalties to put the Cheetahs six points ahead, before a darting run from Landajo and a conversion by Sanchez helped the debutants go in front.
A Sanchez drop goal extended the lead to four points before substitute Daniel Marais reduced the gap to a single point with a Cheetahs penalty.
