Charlie Wyke bagged a brace against his former club, as Sunderland ran out 3-1 winners against Carlisle United in their second pre-season friendly of the summer.
After a goalless first half, Lewis Alessandra put the visitors ahead with a strike from distance before Charlie Wyke levelled proceedings against his former club.
With less than 20 minutes remaining, Chris Maguire came off the bench and slotted home a low cross to put the Black Cats ahead.
And Wyke made sure of victory when he reacted quickest to a loose ball and fired home 10 minutes from time at the Stadium of Light.
Parkinson named a much-changed starting XI from the side that won at Gateshead on Saturday.
Morgan Feeney, Aiden O’Brien and Remi Matthews all made their first starts for the club, while Will Grigg and Jack Diamond were deployed from the off after impressive performances last time out.
Sunderland raced out of the stalls and went close twice in the early stages.
First, Diamond skipped past his man down the left and crossed for Conor McLaughlin, but his header was straight at the Carlisle stopper and moments later, Josh Scowen’s dangerous cross just evaded Grigg.
It took 30 minutes for either side to create another opportunity and it came the way of first-time starter Feeney when the ball dropped kindly to him, but the centre-back struck it high and wide.
Scowen was instrumental every time the Lads surged forward, and he went close towards the end of the first half, as he fired wide from distance.
The visitors hit the front just five minutes after the break when Alessandra’s strike from distance squirmed through the palms of Matthews.
Parkinson made wholesale changes on the hour mark and it was to good effect as Sunderland immediately hit back.
Denver Hume drilled in a low cross from the left and Wyke tapped home unmarked.
And less than 10 minutes later the Lads hit the front for the first time when Luke O’Nien slid in Maguire to slot home.
With 80 minutes on the clock, Wyke made sure of the victory when he reacted quickest to a loose ball, composed himself and fired home.
