Yorkshire Phoenix failed to qualify for the Twenty20 Cup semi-finals last night - but ended their involvement in the competition with a rip-roaring victory over Nottinghamshire Outlaws which had the 10,114 Headlingley crowd in a high state of excitement.

Chasing 197, Notts seemed home and dry at 169 for five in the 17th over but they lost their last five wickets for nine runs in 12 legitimate balls to leave Yorkshire winners by 18 runs.

This triumph, with 11 deliveries to spare, left Yorkshire with a 100 per cent home record and the sheer enthusiasm of the crowd left no-one in any doubt that Twenty20 cricket is here to stay.

The man-of-the-match award went to Michael Lumb for his barnstorming 55 off only 26 balls with five sixes and four fours but the hero of the hour was 18-year-old Tim Bresnan who sparked the collapse with three wickets in four balls, all his victims clean bowled.

First to go was Paul Franks who had his middle stump knocked back and two balls later Jason Gallian heard crashing timber.

Richard Logan went first ball and it was left to Stuart MacGill to survive the hat-trick delivery but in the next over from Lumb he lost Will Smith sparring outside off-stump and the match ended when MacGill gave a return catch to Ryan Sidebottom who flung out his left hand to hold on.

Before Notts disintegrated, South African Kevin Pietersen thrashed 44 from 21 balls with three sixes and four fours but Yorkshire's gamble of bringing on Lumb paid off because Pietersen clipped him straight to Matthew Wood at mid-wicket and later in the over the same combination accounted for Bilal Shafayat.

Winning the toss, Yorkshire lost Yuvraj Singh in the second over to a brilliant overhead catch by Franks but Wood was then able to look on as Lumb launched himself into a salvo of stunning shots.

In left-arm spinner Samit Patel's solitary over, which cost 23, the left-hander plundered three consecutive sixes after Wood had also driven the slow bowler high over the rope.

The onslaught was ended by Gareth Clough who bowled Lumb round his legs as he attempted to sweep but Wood went on to make 57 from 44 balls and the total was boosted by 20 in the final over from MacGill who was cracked for two sixes by Gavin Hamilton and one by Richard Blakey.
