Mako Vunipola and Chris Wyles scored vital tries as Saracens booked their place in the European Champions Cup final with a fine victory away at Munster.
In a tight game, the defending champions were forced to defend for much of the first half as Munster piled forward.
But prop Vunipola and winger Wyles crossed after the break to secure a famous victory, while Owen Farrell’s accurate kicking was crucial to their success.
They will now face either Clermont Auvergne or Leinster in the final next month.
Saracens included all six of their British & Irish Lions in their line-up but fell behind to an early Tyler Bleyendaal penalty after Munster attacked from the off.
But Sarries responded with a flowing passing move down the left which carved Munster open, but Sean Maitland’s pass to Richard Wigglesworth was slightly overcooked.
Farrell coolly slotted over to level the scores minutes later after Andrew Conway failed to roll away from a tackle, but the visitors spent much of the first 20 minutes on the back foot.
Jackson Wray’s yellow card handed a major advantage to the home side but Sarries’ immense defence stood firm.
And they were awarded five minutes before the break when Farrell slotted over another penalty to lead 6-3 at the break.
Saracens had two great chances to score the game’s first try early in the second half, but Chris Ashton dropped a pass when in a great position out right and George Kruis spilled the ball when reaching for the line.
The gangly lock spotted a gap five metres out and surged through but lost the ball at the vital second.
But minutes later they did cross as Vunipola powered over from close range after an expert Richard Wigglesworth pass, with Kruis adding extra muscle to the attack.
Farrell added another penalty shortly after the hour mark to give Saracens a 13-point lead, and Munster’s Bleyendaal missed two great chances to cut the deficit – one with a penalty that he pushed wide and then a drop-goal which hit the post.
And Saracens made them pay as Farrell’s expert kick through was collected by Wyles and he touched down.
Munster claimed a late try through CJ Stander, who muscled his way over from close range but the day belonged to Saracens.
