Opener Toby Albert continued his superb form in the T20 Blast to help Hampshire Hawks beat Durham by 26 runs and reach Finals Day for the 11th time.
Albert was the fifth-highest run-scorer in the group stage, with 472 runs, and he picked up where he left off, making 68 in 37 balls with four sixes.
Opening partner Chris Lynn, with 51 in 27 deliveries, and then Hilton Cartwright, 61 in 31 balls, saw Hampshire pile up 221-8, the highest score by an opposition at Chester-le-Street.
Faced with making their highest T20 chase, Durham were always struggling and could only reply with 195-6, with Ollie Robinson making a late 60 from 33 balls.
Hampshire will now play Northamptonshire Steelbacks in the first semi-final at Edgbaston on Saturday, 13 September, while Durham continue to wait for a first Finals Day appearance since 2016.
Lancashire face Kent (14:30 BST) and Somerset host Bears (18:30) in the last two quarter-finals on Saturday.
