|Friends Life t20, Headingley|
|Yorkshire 152-7 beat Worcestershire 150-7 by two runs|
Gareth Andrew smashed 60 off just 26 balls as Worcestershire fell just short in a dramatic Headingley finale.
Yorkshire looked on for an easy first FL t20 win when, after posting 152-7, they had the visitors in trouble on 67-5, with Vikram Solanki out for 28.
Big-hitting Andrew then blasted five fours and four sixes in a 59-run sixth wicket stand with James Cameron (28).
But, needing four to win off the final ball, Worcestershire managed just a single, to lose by two runs on 150-7.
Yorkshire's first Twenty20 win of 2011 leaves Bradford-born Steve Rhodes' Worcestershire still looking for their first victory of the season after three of their 16-game marathon.
Yorkshire's first North Group win of 2011 was a desperately close run thing - but just the tonic they needed ahead of Friday night's Roses clash at Old Trafford.
Man of the match Richard Pyrah captured four wickets for 21, while Adil Rashid was also comparatively tidy, taking 3-19.
But the real star performer was Andrew, who followed up his 3-30 with the ball by despatching his celebrated Mongoose bat to all parts, as he rattled up comfortably his best Twenty20 score.
After striking David Wainwright for two big sixes and a four in one over, he hammered Steve Patterson for four and six to take his side into three figures.
Even after Cameron went in another double-wicket over from Pyrah, Andrew refused to give up the fight and Ryan Sidebottom had to bowl the final over with 12 wanted.
Shaaiq Choudhry drove his first ball for three but, when Andrew could only run a bye off the fifth, his partner needed a boundary to win it for Worcestershire but failed to make contact and the pair could only scamper another bye.
Worcestershire are also in action on Friday night, at home to Northants at New Road (1730 BST).
