River Plate and Velez Sarsfield served up a four-goal thriller that neither side could quite finish, ending level at 2-2 in a match that swung hard both ways. River went ahead early when Correa struck in the 11th minute with an assist from Martinez Quarta, but an own goal from Silvero on the stroke of halftime levelled things up at 1-1. Velez looked sharp after the break and took the lead through Valdes in the 61st minute, set up by Pellegrini, only for Lanzini to seal a draw with a late finish from Gomez's assist in the 79th. It was an open, end-to-end affair that neither team could control.

Our model came into this one calling a 1-0 River win, pricing a draw at just 30 per cent—so the 2-2 finish landed well outside our main lean. We'd flagged River as slight favourites on form, though both teams came in with defensive frailties and a history of draws between them. The match unfolded with more goals and more back-and-forth than we'd banked on, with Velez matching River's attacking intent rather than sitting deep. The own goal was obviously a freak ingredient we couldn't have factored in, but the end result was more open and more even than our model had weighted it. Sometimes a game just plays out differently than the numbers suggest—and this was one of those nights.
