Hal Robson-Kanu stepped off the bench to bag the winner before seeing red in a crazy 20-minute cameo at Turf Moor.
The Welshman made himself a hero when he fired past Tom Heaton 19 minutes from time.
But the striker soon became a villain.
Referee Martin Atkinson with no option to brandish a red card after Robson-Kanu led with his elbow in an aerial challenge with Matthew Lowton.
Albion’s class of 2017 were far from at their best in a game Burnley dominated on chances and territory.
But into the record books they go with Albion winning their opening two games for the first time in the Premier League era.
Jonny Evans did not travel with the squad fuelling speculation the centre-back is Manchester City bound.
City are understood to be readying a second offer for the Northern Irishman having had a reported £18 million advance dismissed.
Tony Pulis insisted before the game Evans was struggling with a hamstring injury and that the 29-year-old would play if fit.
Claudio Yacob’s hamstring injury presented Pulis with the ideal opportunity to blood new signing Gareth Barry.
Barry, signed from Everton midweek, made his 629th Premier League appearance but first for Albion in a new-look midfield.
A midfield that blended youth and experience, with teenager Sam Field and Jake Livermore alongside the 36-year-old.
James McClean showed no signs of weariness following a new arrival to his young family this week.
The Republic of Ireland pressed from the front, as he did against Bournemouth, and his desire nearly paid dividends as early as the first minute.
Charging down Matthew Lowton’s clearance, McClean advanced towards goal but saw his shot blocked.
The home fans had to wait until the 18th minute for their side’s first real glimpse of goal.
Jeff Hendrick’s half-volley bouncing past the post following Jack Cork’s squared pass.
Burnley dominated possession, as most teams tend to against Pulis’ Baggies, and slowly began to make the better of the openings.
Johann Berg Gudmundsson curled wide after Sam Vokes outmuscled Craig Dawson in the air.
The Iceland international then had Ben Foster scrambling across goal to gather a header.
Albion struggled to make in-roads with their approach play all too predictable and easy to defend.
Defensively, they continued to work hard to close off the space.
Yet Vokes found himself in acres, but unfathomably failed to make contact on Robbie Brady’s inviting centre.
Sam Field knew little about Albion’s best chance of the opening period.
Phillips’ inswinging corner was helped on at the near post by Rodriguez and towards Field who couldn’t shift in time to direct his header on target.
And still the chances came for the hosts.
Ben Mee heading wide after meeting Brady’s corner at the far post.
Burnley picked up from where they left off after the break with Vokes steering Gudmundsson’s cutback over Foster’s crossbar.
The visitors had the ball in the net two minutes into the second half.
Only for the offside flag to be raised with Rodriguez offside in the build-up to Livermore’s deflected volley.
Attempting to cap his 500th competitive match with a goal, Brunt went for the sticks with a 52nd minute free-kick.
From such an awkward angle, a cross might have been the better option.
Quiet first half, Phillips started to make more of an imprint on the match.
After a strong run, which earned a corner, he drifted in-field and worked the ball on to his left before unleashing from distance.
He has the ability on his left-side, but this effort wasn’t one of his best.
Likewise Brady, who fired staright into the wall from a free-kick 20 yards out after Dawson had fouled Hendrick.
It was a reprieve the Baggies took full advantage of five minutes later.
Robson-Kanu beat James Tarkowski to Phillips’ flick on and held the young Englishman off before slotting past Tom Heaton at his near post.
A little against the run of play, but not so much as if it had arrived first half.
The Welshman wasn’t done, heading over from Rodriguez’s cross moments later.
Burnley substitute Ashley Barnes fired over on the turn.
But Robson-Kanu was not out of the spotlight for long, leading with his elbow in a challenge that surely had to merit a dismissal.
There was still time for Vokes and then Jonathan Walters to squander more chances for the hosts who can blame their defeat on woeful finishing.
New boy Barry took up the Yacob holding role in front of the back four.
Understandably, he was a little tentative at first as he adjusted to his new surroundings and team-mates.
But the former England man steadily became more of an influence as the match wore on.
Burnley certainly matched Albion in the physical battle, with Vokes a real handful all afternoon for both centre-backs.
Not a whole lot for the travelling Baggies to cheer first half.
And when they did cheer after the break it was in vein with Livermore’s deflected volley ruled out for offside.
The Albion fans demanded to see Robson-Kanu long before he arrived.
Maybe Pulis should have listened to the sooner.
Six points from two games is a decent return, especially when you throw in one pretty poor performance.
A home clash with Stoke, tasty for so many reasons, beckons.
Playing poorly and still picking up points is not a bad habit to acquire.
Albion, at the time of writing, up to second.
Bask in it Baggies.
