TWENTY20 CUP SEMI-FINAL, The Rose Bowl:
Middlesex 141-2 (15.4 overs) beat Durham 138-6 (20 overs) by eight wickets
Henderson is the world's leading Twenty20 wicket-taker
Tyron Henderon's brutal innings steered Middlesex to an eight-wicket win over Durham and a place in the Twenty20 Cup final against Kent at the Rose Bowl.
The South African hit seven sixes - including three off Steve Harmison - on his way to a memorable 59 off 21 balls as Middlesex overhauled Durham's 138-6.
Tim Murtagh (3-29) was the pick of the Crusaders bowlers, while Shivnarine Chanderpaul's 48 was Durham's best.
Ed Joyce struck 41 before Henderson's incredible innings sealed the victory.
The all-rounder came to the crease as Middlesex's run chase faltered after losing two quick wickets with the total on 65.
Henderson proceeded to smash recalled England fast bowler Harmison for two successive sixes - one back over his head while the second was dispatched over deep mid-wicket.
Off-spinner Paul Wiseman was the next to suffer Henderson's rage, launched for a six over mid-wicket before two further maximums went straight over the former New Zealand Test player's head in his next over.
And fittingly, Henderson clinched Middlesex's place in the Twenty20 Champions League with yet another six off Harmison - who went for 47 from his 3.4 overs - as the Londoners sealed victory after just 15.4 overs.
With a pitch receptive to turn, Middlesex's two spinners - Shaun Udal and Murali Karthik - constricted Durham's run supply in the middle overs after Paul Collingwood's breezy 34.
After losing openers Michael di Venuto (0) and Phil Mustard (15), Collingwood and Chanderpaul looked set to give Durham a sizable total.
But veteran off-spinner Udal struck in the 10th over when Collingwood chipped a leg glance to the deep mid-wicket boundary, where Billy Godleman took a fine low catch.
The dismissal stunted Durham's progress as Udal and left-arm spinner Karthik conceded just 18 runs each from their four overs.
Late hitting from Shaun Pollock (15) - who dispatched Murtagh into the radio commentary box in the penultimate over - gave Durham's bowlers a tangible target to aim for.
With a modest total to chase, Middlesex made a solid, if unspectacular, start.
With no urgency for big runs, Joyce and Godleman patiently amassed a 65-run opening partnership without the need for extravagant shots.
Captain Joyce was the more adventurous of the pair, using his feet to hit boundaries off Liam Plunkett and Pollock.
Spinner Gareth Breese made the breakthrough in the ninth over, trapping Godleman lbw in front for 20.
And Wiseman followed suit when he had Joyce stumped, luring him down the wicket before beating him with prodigious turn.
But Durham's victory hopes evaporated as Henderson launched into their battered bowling attack, booking Middlesex's place in the Stanford Series in Antigua in late October.
Durham captain Dale Benkenstein:
"They have two very experienced spinners and they never allowed us to get going.
"We were in a good position at round about 13 overs and if we'd have kicked on from there it may have been different but we just weren't able to hit boundaries."
On recalled England fast bowler Steve Harmison: "He's been outstanding in all forms of the game. He's got great control at the moment, he's bowling with great pace and I think he's ready to get back into the Test side.
"He's got pace and bounce and will bring a fear factor into the game. He adds a good balance to the side and I don't think the tail will be hanging around with him in the team."
