On-loan Liverpool goalkeeper Harvey Davies was the hero as Crewe pulled off a shock EFL Cup penalty shootout win at Sunderland.
The 19-year-old saved Pierre Ekwah's kick, with all five Alex players hitting the target.
That put a dampener on a historic evening for Sunderland striker Chris Rigg.
Rigg's goal, just 51 days after his 16th birthday, made him the youngest goalscorer in Sunderland's history, after he became their youngest-ever outfield player last season.
Skipper Luke Offord headed Crewe in front in first-half injury time.
Rigg's goal temporarily denied them the win and they had the outstanding Davies to thank for a fine save from Bradley Dack deep into added time.
