The Southampton striker came off the bench to net the deciding goal with his first touch of international football on Wednesday night, with the Three Lions twice coming from behindA goal from debutant Rickie Lambert gave England the win as it claimed a 3-2 success over Scotland in a thrilling friendly at Wembley.
The Southampton forward headed home a corner with his first touch of the ball to hand the hosts victory in the first meeting between the bitter rivals in 14 years.
James Morrison and Kenny Miller had twice given the Scots the lead earlier in the match, only for Theo Walcott and Danny Welbeck to cancel out the advantage on each occasion.
Lambert's goal provided a fitting end to a fabulous contest, which saw England avenge its 1999 defeat to the Scots at Wembley.
Roy Hodgson named a strong side for the encounter, making the most of a rare opportunity to field Jack Wilshere alongside Steven Gerrard in midfield, while Wayne Rooney ended all doubts about his injury status by taking a place up front.
Meanwhile, Scotland boss Gordon Strachan looked to the experienced Miller to lead the line, with the fit-again Scott Brown also included in central midfield for a match where the Celtic man's oft-referenced battling qualities would be required.
The game certainly started in a confrontational manner, with the booing of national anthems setting the scene for some feisty early tackles in an intense opening.
Scotland took the lead with just 11 minutes on the clock, as Morrison's well-hit strike from the edge of the box squirmed underneath Joe Hart's poor attempted save to send the visiting fans into raptures.
It took until the 26th minute for the hosts to provide the home fans with something to cheer, as Tom Cleverley went close following a delightful lay-off inside the box from Rooney.
And just three minutes later, England was level.
Walcott darted in from the right to latch onto a well-weighted Cleverley through ball and deceived Steven Whittaker, before squeezing the ball in left footed at the near post to restore parity.
England was much improved after its equalizer, and was only denied a second goal shortly before the break by an incorrect decision from the assistant referee.
Rooney was the unlucky recipient of the official's attentions, with the Manchester United striker wrongly flagged offside after collecting a Gerrard pass in the box on his chest and controlling the ball to fire home.
Wilshere was the only man to depart at halftime, as the Arsenal midfielder made way for Frank Lampard with his troubling injury record clearly in mind, but there was little time for England to adjust to the tactical consequences before it fell behind for a second time.
Miller did brilliantly to hold the ball up on the edge of the box before turning a hapless Gary Cahill to smash home on his left foot, much to the dismay of the shell-shocked hosts.
But, unlike in the first half, it did not take long for England to muster a reply.
Just two minutes after Allan McGregor produced a brilliant save to keep out Gerrard's free-kick, the England captain picked out Welbeck with another pin-point set-piece delivery which the Manchester United forward gratefully headed in.
A flurry of substitutions from both sides, which saw Lambert handed his debut, followed - and the striker soon had his dream moment.
The 31-year-old rose highest to meet a Baines corner from the left and directed the ball brilliantly home with his head to put the hosts ahead for the first time in the 70th minute.
Chances were at a premium for the remainder of the game, but Lambert had one last opportunity to double his account in the dying moments.
However, the striker could only hit the post from close range following a cross from the right, though it is unlikely the miss will play on his mind much after a near-perfect debut.
