San Martin (SJ) went out with an offensive proposal, though they did not find too many clear chances. River, on the other hand, had less opportunities to score. Despite that, the clearest shot of the match arrived on behalf of Mauro Rosales towards the end of the game.
As for the new jerseys, the second kit I speculated has been confirmed on River's official website. Still, there is a lack of updates on the third jersey, but some sites seem to indicate that it will be a plain purple shirt (pictured to the right). We'll see what happens with that.
