Yorkshire are 8/5 favourites to be crowned kings of the north after completing the line-up for NatWest T20 Blast Finals Day.
The Vikings brushed aside Glamorgan on Thursday evening to make it four wins from four for the North Group in the quarter-finals.
A record Cardiff crowd of over 10,000 watched the hosts bowled out for just 90 en route to a crushing 90-run defeat, with leg-spinner Adil Rashid taking four for 26.
England all-rounder David Willey was the star of the night with the bat, blasting 79 from 38 balls to help Yorkshire reach 180 for eight off their 20 overs and that proved more than enough as Glamorgan crumbled in front of their home support.
Yorkshire could be further boosted by the availability of England duo Joe Root and Jonny Bairstow for Finals Day next Saturday, when they will first face 9/2 outsiders Durham, who beat Gloucestershire by 19 runs in Wednesday’s quarter-final.
Yorkshire have never won the 20-over competition and captain Alex Lees told BBC Wales Sport: "We were exceptional with the ball and in the field, we kept taking wickets, I'm really proud of the lads. I'd be delighted to be Yorkshire's first T20 winning captain but we need to beat Durham first and go one game at a time.”
In the other semi-final, 9/5 second favourites Nottinghamshire will be expected to progress at the expense of Northamptonshire, who are 4/1 to go one better than last season when they lost in the final to Lancashire.
Nottinghamshire beat Essex by 39 runs in the first quarter-final thanks to Samit Patel's career-best Twenty20 bowling figures of four for 20, while Adam Rossington's unbeaten half-century comfortably led Northants to a seven-wicket victory over his former county Middlesex at Wantage Road.
