Somerset secure semi-final berth...Must Watch

Somerset 146 for 4 (Kieswetter 56*, Botha 1-20) beat Warriors 134 for 8 (JJ Smuts 38, Thomas 2-16) by 12 runs

Scorecard and ball-by-ball details

Somerset's captain Alfonso Thomas bowled two strangling spells to ensure his side beat Warriors and qualified for the semi-finals of the Champions League Twenty20. Warriors' loss meant their net run-rate fell below that of Royal Challengers Bangalore and they became the second South African team, after Cape Cobras, to bow out of the tournament in two days.

Ironically, it was the performance of three South Africa-born players that contributed most to Somerset's victory. Thomas' 2 for 16, Craig Kieswetter's unbeaten 56 and Roelof van der Merwe's all-round effort closed the door on Warriors.

With the ball turning, and not coming on to the bat, Warriors had to be careful not to fall too far behind the required run-rate. They slipped in the middle stages but it was only in the 19th over - with 23 runs needed off 12 balls - that the match went beyond their grasp. Thomas bowled slower balls throughout, and when he removed big-hitting Craig Thyssen and Wayne Parnell in the same over, the task became too great for Warriors.

They had started positively, as Ashwell Prince and JJ Smuts scored 24 runs in the first three overs. Prince was the first batsman undone by the lack of pace but Smuts formed a solid partnership with Ingram. They battled through a lean patch but struggled to find the boundary, especially against Thomas and young Adam Dibble, who bowled a tight second spell after conceding 13 runs in his first over.

After steering Warriors to 79 in the 12th over, however, both Ingram and Smuts were dismissed in the space of five balls and the new Warriors batsmen could not keep up. Johan Botha, batting at No. 5, tried to take Steve Kirby on but sliced a slow and wide ball high to Arul Suppiah in the deep, who put it down. Three balls later, Botha did the same thing and was caught at long-off.

Nicky Boje and Thyssen were left to score 46 runs from 27 balls. Both tried a few shots but with Somerset's bowlers not giving much away, they were unable to set-up the win. The margin of defeat was a sizeable 12 runs in the end.

Warriors had started the game brightly, with the wicket of Peter Trego, who was caught behind in the first over after Lonwabo Tsotsobe created pressure with his short of a length deliveries. That good work was completely undone by Wayne Parnell in the second over. Parnell bowled a poor line, conceded 13 runs, and did not bowl for the rest of the innings.

Kieswetter took advantage of Parnell's wayward leg-side line but it was van der Merwe who sunk his teeth into his countrymen, taking 16 runs off Tsotsobe's second over. Somerset's acceleration prompted Botha to change the pace and he introduced left-arm spinner Smuts, who bowled too short in his first over. van der Merwe caned Smuts for two more fours but succumbed to his attacking instinct, top-edging a slog sweep to midwicket to fall for 32 off 16 balls. Botha and Boje took control between overs seven and ten, giving away 18 runs and only one boundary, as they tied Kieswetter and James Hildreth down.

Rusty Theron started his spell with a wide ball that was hit through point for four but recovered well, with fuller and slower deliveries that could not be punished. Botha also juggled his spinners to good effect but four shots spoiled his effort: Kieswetter's pull over midwicket off Botha, Jos Buttler's two sixes off Boje - the second of which was the second biggest of the tournament - and Buttler's straight smack over the sightscreen off Smuts.

Tsotsobe and Theron had to bowl at the death and used variations such as cutters and slower balls. Most of their deliveries were on target but Kieswetter punished anything that wasn't. He hit boundaries in three of the last four overs, and was the reason Somerset were able to score 36 runs off them.

Ashes hero Dilley dies aged 52...2011

The former England fast bowler, Graham Dilley, has died aged 52 after a short illness.

One of the quickest bowlers of his generation, with a memorable surge to the crease, Dilley took 138 Test wickets at 29.78 for his country but his best-remembered contribution to the England cause came with the bat - he made 56 supporting Ian Botham in a 117-run partnership which helped England to a famous Ashes Test win over Australia at Headingley in 1981.

In a ten-year international career, Dilley played in 41 Tests and 36 ODIs. Remarkably, he finished on the winning side in just two of those Test appearances, but in an era of limited success for the England team, those two victories were among the most loudly acclaimed of the decade - in addition to Headingley, he also played a key role in the first Test of the 1986-87 Ashes triumph, at Brisbane, where his first-innings figures of 5 for 68 condemned Australia to the follow-on.

In the entirety of his first-class career, Dilley claimed 648 wickets at 26.84 for Kent, Worcestershire, England and Natal, although his highlight was arguably the role he played in spearheading Worcestershire's back-to-back County Championship title-winning sides in 1987 and 1988.

"I had a lot of great times with him," Botham told Sky Sports News. "He had a good sense of humour and always wanted to be a part of the party. He was quiet and reserved until you got to know him. It's a very sad day. We both joined Worcestershire at the same time together, almost within minutes. We had a great run of about six trophies in five years."

Dilley's international career was curtailed in 1989 by his decision to join Mike Gatting's rebel tour of South Africa, but by that stage his jolting delivery stride had already taken a heavy toil on his knees. In his later years, he was troubled by osteo-arthritis, and he retired in 1992.

In the immediate aftermath of retirement, Dilley suffered financial problems, but found a new lease of life after moving into coaching. He enjoyed spells as an assistant coach with England and then bowling coach to the England women's team, before taking up a position as head cricket coach at Loughborough University. One of his pupils there was Monty Panesar, "So sad to hear my Uni coach passed away," Panesar tweeted. "Great man and top coach. [He] did a lot for me."

ECB chief executive David Collier said: "Graham made a life-long contribution to the game of cricket at all levels and we are deeply saddened by the sad news this morning. He will be fondly remembered for his contributions both as a player and a coach.

"Graham inspired many young cricketers through the University programme and was a highly respected coach to our representative teams. Few will forget his contribution during the historic Ashes win at Headingley in 1981 and the part he played in two Ashes series victories. Graham will be sadly missed by all his friends throughout cricket and ECB sends our deepest condolences to Graham's family. '

Hugh Morris, the managing director of the England team said: "This is very sad news for Graham's many friends and colleagues in cricket both in this country and overseas. As well as being a bowler of the highest class, Graham made an immense contribution to our game as a coach and his ability to impart his knowledge and wisdom to future generations of young cricketers will be sorely missed.

Last-ball six takes RCB into semis..2011

Royal Challengers Bangalore 215 for 8 (Dilshan 74, Kohli 70, Tait 5-32) beat South Australia Redbacks 214 for 2 (Harris 108*, Ferguson 70) by two wickets

Arun Karthik produced the six most important runs of his 15-match Twenty20 career off the last ball of the CLT20 league phase to propel Royal Challengers Bangalore past South Australia Redbacks in a game that had everything except for a Super-Over finish. It featured an astonishing century from Daniel Harris - only the third in Champions League history. It had a five-for from Shaun Tait, in a game where 429 runs came off 40 overs. It also featured sublime stroke play from Virat Kohli, who played his best T20 innings. It had strong helping hands from Callum Ferguson and Tillakaratne Dilshan.

It all boiled down to the last ball, off which six were needed, and Karthik stepped up to smash Daniel Christian into the stands beyond midwicket. The crowd went up as one, the RCB dug-out exploded in joy, and even the usually laidback Chris Gayle walked out shirtless with a broad smile.

In a game that unfolded like a Hitchcock whodunit, it was fitting that the winning blow came off the bat of someone who was playing only because AB de Villiers was injured. At the other end was S Aravind, the worst bowler of the day, who got close to redemption with a boundary off the third ball of that electric final over. Christian bowled a slower ball on the fourth, which Aravind slogged for two, making it seven needed off the last two. Aravind couldn't connect with the fifth, but the batsmen scrambled through for a bye. Six needed off one, and Christian delivered a slower ball as hittable as Chetan Sharma's infamous full toss to Javed Miandad in Sharjah. Karthik coolly stayed in his crease and heaved with all his might over midwicket to become a hero.

It was heartbreak for the Redbacks, who had somehow regrouped after a virtually unstoppable 100-run stand between Kohli and Dilshan off 8.5 overs. By the time Kohli fell, he had reduced the equation to 50 off the last five overs, but RCB's light-weight middle order gave the Redbacks a chance. Nathan Lyon piled on the pressure with a four-run 16th over, but Tait ceded the advantage with two sixes in the 17th, though he managed to dismiss Saurabh Tiwary. The next over from Aaron O'Brien also produced two sixes and a wicket, making it 18 required off 12 balls. Tait then lasered Dilshan's stumps with a stunning yorker and got Daniel Vettori to miscue, before completing his five-for with Raju Bhatkal's wicket. That set up the last-over climax, Christian blinked after five balls, and Karthik held his nerve to complete the first win for an IPL side against an Australian team.

The performances from Tait and Karthik dominated the ending, but the contest got its substance from Harris and Kohli. Both produced innings that had no business featuring in an unabashed exhibition for T20 batting. Harris' effort stood out for the shots he didn't play - he went almost 18 overs without trying to hit a six, and yet coasted to a century with time to spare. Kohli's was elevated by the shots he chose to play. Faced with an asking-rate nearing 11, and with Gayle dismissed, Kohli unfurled a series of astonishingly correct strokes.

Equally telling were the chalk-and-cheese support acts from Ferguson and Dilshan. With the spinners pulling things back after Harris' Powerplay boundary blitz, Ferguson took his time settling in before opening up in style. Dilshan, on the other hand, ignited RCB's chase with a series of outrageous strokes, which included a couple of trademark scoops.

Gayle was more subdued at the start, but he gradually found his range to muscle three sixes, before Michael Klinger caught him in the deep even as he collided grievously with Tom Cooper. Kohli walked in like he belonged in the cauldron, and opened his account with a pulled six through wide long-on. The slowness of the pitch and the variations of the Redbacks attack could not stop him from hitting through the line, and repeatedly in front of the wicket. He charged out to O'Brien and launched him with the turn over long-off, before carving Richardson for the shot of the day - an inside-out six into the stands behind extra-cover. He then gave Harris a taste of his own medicine, taking him for two sixes and three fours in the 13th over to put RCB on course for a heist.

The script was completely different in the first half of the match as, for the second night on the trot, an IPL side took a hiding from an Australian batsman. Aravind's pathetic lengths made this considerably easy - he finished with figures of 4-0-69-0, the second worst in T20 history - but that could not take any credit away from Harris.

The floodgates opened in the second over, when Aravind sent down a series of slow freebies angled into the hitting zone. Harris gratefully opened up his stance and carved boundaries straight, square and fine through the off side to set the Redbacks on their way. Kohli missed a run-out in the next over, and Harris celebrated by smashing seven of his next eight balls for fours. Vettori daringly persisted with Aravind for the fourth over, only to see him repeat his predictable lengths from either side of the stumps. Harris indulged himself to move to 43 off 19 balls by the fourth over, and Vettori was left playing catch-up for the remaining 16.

With the spinners coming on, Harris settled into cruise-mode, while Ferguson assuredly got his eye in. Just when the momentum seemed to be flagging a touch Aravind returned, and the Redbacks resumed their run-glut. Having taken two fours and a six off Aravind's 16th over, Ferguson thumped Nannes emphatically for a six off the first ball off the 17th. He holed out in the 18th over, prompting Harris to finally attempt a big hit. He pounded Bhatkal over midwicket for his first six, before dumping Nannes behind square-leg to bring up the century. Incredibly, Aravind got the 20th over, and Christian duly bludgeoned five more fours to take the Redbacks to 214.

Twenty overs later, Christian and Aravind had their roles reversed. And how.
