Moeen Ali slammed an unbeaten 60-ball 121 to power title-holders Worcestershire to an uncomplicated eight-wicket win over Sussex in the third quarterfinals.
Moeen's breezy knock featured eight boundaries and 11 towering sixes as Worcestershire cruised to the target of 185 with 14 deliveries to spare.
Leading from the front, Rapids skipper Moeen displayed pristine striking as all of his lusty blows travelled deep into the stands.
Home side Sussex were earlier helped by a brutal assault from opening batsman Philip Salt, who top-scored with 72 off 40 balls.
Sussex's blazing start was disrupted in the middle overs as they suffered a mini-collapse losing three wickets for 14 runs before Laurie Evans stabilized the innings and upped the scoring rate towards the end.
Off-spinner Moeen kept things tight drying up the runs from one end as he registered figures of 1-22 in four overs while Ed Bernard contributed with two wickets and gave away just 21 runs.
Worcestershire's start to their chase was far from ideal as they lost Joe Leach on the third ball of the innings.
Moeen, coming in to bat at No. 3, then stitched a 177-run partnership with Riki Wessels, who was the calmer of the two and accumulated 47 off 46 balls.
Since announcing his decision to take a short break from international cricket, the 32-year-old England southpaw has racked up two blistering half-centuries to go with his sublime ton.
His attack was evenly spread out against all opposing bowlers as Moeen reached his second T20 century from a sleek leg-side flick off Will Beer.
