Jacob Mellis and Chris O’Grady were both on the scoresheet as Barnsley drew with Wolves in their second pre-season outing at Oakwell.
The Reds twice had to come from behind to share the spoils with their League One opponents.
Zeli Ismail gave Wolves a second minute lead after he fired home from Jake Cassidy’s cross.
But former Chelsea midfielder Mellis equalised three minutes later after he finished off a good move with O’Grady.
Sam Ricketts restored the visitors’ lead when he headed in a Danny Bath cross.
However just before the hour mark former Sheffield Wednesday O’Grady struck to make sure of a draw.
