Former Tottenham midfielder Teemu Tainio made an appearance as Sunderland routed Cobh Ramblers 4-0 in yesterday's friendly.
Murphy gave Sunderland the lead when he cut inside and finished low into the far corner, before Stokes doubled the score in the 52nd minute with a shot which deceived Cobh goalkeeper James McCarthy.
Roy Keane - back at his first club - gave new midfield signing Tainio his first 45 minutes of action, with the Finn seeing plenty of the ball before the break in a role just in front of the Sunderland defence.
David Meyler, a recent signing from Cork, came on for his debut before Darren Ward saved a 66th-minute penalty from Max Cream, after the Sunderland goalkeeper had been adjudged to have brought down his fellow substitute.
Stokes made it 3-0 in the 78th minute when he tapped in from close range following good work on the left by youngster Nathan Luscombe, before another former Cork player - second-half substitute Roy O'Donovan - netted the game's final goal in the 89th minute.
