Barnsley eased to an impressive 7-1 victory away to York City in their second pre-season friendly.
But the Reds did have to come back from behind after the hosts took a surprise 20th minute lead at Bootham Cresecent.
Jake Wright headed home from a cross to put the Minstermen ahead, but three goals in the space of five minutes saw the Reds quickly get back on track.
Wanted man Tom Bradshaw, who netted a brace in Saturday’s 2-0 win away to Gainsborough Trinity, levelled in the 37th minute with a tap in from a Kieffer Moore cross.
Then midfielder Brad Potts put the Reds in front less than four minutes later and Moore netted three minutes before the break with a close-range effort.
New boss Daniel Stendel made ten outfield changes at half-time, with only keeper Jack Walton keeping his place between the posts.
The starting team was Walton, McCarthy, Lindsay, Jackson, Fryers, McGheean, Isgrove, Potts, Hedges, Moore, Bradshaw; followed by a second half team of Walto, Cavare, Pinnock, Williams, Pinillos, Adeboyejo, Bird, Mowatt, Mottley-Henry, Thiam, Moncur.
And the Reds bagged three more goals after the break. Midfielder George Moncur scored from the penalty spot in the 51stminute, before Mamadou Thiam grabbed a sixth having hit the upright twice earlier.
Dylan Mottley-Henry put the icing on the cake with nine minutes left to make it a good night’s work from the visitors.
Meanwhile, the Reds have signed promising teenage winger Louis Walsh on a permanent contract.
Walsh, 17, was on trial at Oakwell last season and was a regular for the club’s Under-23s side who play in the Professional Development League.
He joins fellownew arrivals Jordan Barnett, Tai-Reece Chisholm and Elvis Otim, all of whom are expected to feature for Martin Devaney’s Under-23 team.
“I’m all settled now and I can’t wait to start playing again with a manager I believe in and who believes in me,” said Walsh.
“I’m still 17, but I truly believe in my ability and journey. I’m pleased to finally get it [the deal] all done.
“Coming up from down south has been tough, having to get used to the area and culture – it’s a lot different to where I’m from and what I’m used to.”
