Despite dominating the match, the away side found themselves two goals down after 27 minutes thanks to strikes from Martinez and an own goal from Willian Arão which gave Unión la Calera a healthy lead. Gabriel's penalty just four minutes later helped his side claw back into the game, before Arão made up for his previous error and equalised just 13 minutes from time.
With the spoils shared in Chile, group G remains unchanged. Flamengo stay top, now six points clear, while Unión remain rooted to the bottom with just two points from four games.
