Who holds the worst record in cricket which is unbeaten till now?

 Robin Peterson, South Africa - Most expensive over by a Full-Member bowler

Robin Peterson holds the infamous record of most runs conceded by a Full-Member nation player in one over in One Day International history. Sri Lanka's Thisera Perera hit South Africa's left-arm-spinner for 5 sixes and a four in a match between Sri Lanka and South Africa in 2013 at Pallekele.

Peterson conceded runs in this sequence in the 33rd over: 6, Wd, 6, 6, 6, 4, 6.

The player conceded 35 runs in an over, which is the second worst over in ODIs. Van Bunge of Netherlands conceded 36 runs in an over in a World Cup Match against South Africa in 2007.

Despite conceding 35 runs in one over, Robin Peterson ended with an impressive match figure of 1/51 in seven overs. South Africa won the game convincingly by 56 runs. Peterson retired from all forms of the game on November 9, 2016.

Salman Butt, Pakistan - Worst duck-to-innings ratio

Salman Butt got out for a duck once in every five games in the 78 ODIs he played for Pakistan

Salman Butt holds this unprecedented infamous record. He got out for a duck once in every 5 innings. This is the worst duck-to-inning ratio for any batsman in ODIs. Salman Butt represented Pakistan in 78 ODIs. He has gotten out for a duck in an incredible 15 games. This is a surprising statistic for an opening batsman who maintained a healthy average of 36.82 with eight centuries and fourteen fifties. The second batsman in this list is Sri Lankan R. Kaluwihtharna, who has a duck-to-inning ratio of 1:8.

Though Sanath Jayasuriya holds the record for most number of ducks in ODIs (34), his duck-to-innings ratio is 1:13. Similarly, Shahid Afridi's duck-to-inning ratio is 1:13 which is far better than Salman Butt's 1:5.

Mick Lewis, Australia - Most expensive bowler in ODI history

Mick Lewis holds the infamous record of most runs conceded by a bowler in ODIs

Most cricket fans remember Mick Lewis, the former Australia fast bowler, for his 0 for 113 in the famous 438 chase in the deciding ODI between South Africa and Australia in Johannesburg eleven years ago.

The myopic nature of human mind was evident in Mick Lewis scenario as everyone forgot Herschelle Gibbs was dropped on 44, and then on a 108 on his bowling. Mick Lewis was then dropped out of the Australian Team. He never made a comeback to the International circuit.

David Boon, Australia - Slowest century in ODI history

Boon took 166 balls to score his century, the slowest hundred in ODI history

David Boon was an amiable opening batsman who established an outstanding rapport with his fellow opening batsman Geoff Marsh in assisting Australian Cricket team to recuperate from the poor showing of the early 80s.

In the Benson & Hedges World Series at Hobart on 10th December 1991, India won the toss and chose to bat against the Australians.

The mighty Australian bowling line-up dismissed India for a paltry 175. It was an effortless chase for the Australians where David Boon played brilliantly according to the match scenario.

The opener obtained a century off 166 balls and was declared as a Man of the Match. However, this infamous record is still with David Boon.

Mohammad Sami, Pakistan - Longest over in an ODI match

Sami bowled a 17-ball over which the longest over in cricket history

The unfortunate bowler who bowled the longest over in One Day International cricket was Pakistan's Mohammad Sami, with the third over of the match against Bangladesh in Asia Cup in Colombo in 2004.

He bowled four no-balls and seven wides in that over. The sequence of the over was: wd-4-2-nb-wd-nb1-0-wd-wd-0-wd-nb-wd-wd-nb-0-4. Ironically, Mohammad Sami's earlier over had been a wicket maiden, so he had the bizarre bowling figure of 2-1-22-1.

The team management defended Sami by explaining that he was attempting to remodel his bowling action and was struggling to find rhythm.

The longest over in a Test is believed to be one of 15 deliveries - including nine no-balls - by Curtly Ambrose for West Indies against Australia at Perth in 1996-97. So, Sami holds the record of longest over in the cricketing history.

Was Brian Lara's 400* the most selfish cricket inning ever?

 In this particular series, England had won all the previous three matches and they came to Antigua with a clean sweep in mind. Brain Lara (haven’t gone past 50 in this series) was in tremendous pressure before this match. WI bowlers didn’t get 20 wickets in any of the match in the series.

After Ganga was dismissed for just 10, Lara came in to bat. He takes time to settle where at the other end Chris Gayle attacked the English bowlers before being dismissed. Lara grind out and survived a raucous fourth-ball appeal for caught behind off Steve Harmison

By the end of the first day he had made 86 out of 208 for 2; by the end of the second he was on 313 out of 595 for 5. His concentration was all the more remarkable given he later admitted to Thorpe he had struggled to sleep and only managed a couple of hours each night.

On third day, Twenty minutes before lunch Lara hoisted Batty into the Viv Richards pavilion to equal Hayden's record. The next ball was swept for four and the record was his again after it had been only 185 days in Australia. He jumped in the air and knelt to once more kiss the pitch.

Lara score 400 runs (not out) in 582 balls with a strike rate near to 70 which was not bad in test cricket. He scored 43 fours and four sixes in this innings. It was one of the great innings in cricket history. It provides inspiration to lot of kids in Caribbean.

A weary England side were bowled out for 285 - Flintoff making an unbeaten 102 - and followed on 466 in arrears. But West Indies lacked the firepower to bowl them out again, and after Vaughan made 140, the match drifted to a draw, with England 422 for 5.

The records and plaudits were Lara's but the series was lost. As he said after the match. "I am very happy, but at the end of the day my spirit is still dampened by the series result."

If WI bowlers would have taken 20 wickets, then there would be no questions like this. A lot commented about the pitch which doesn’t have anything for the bowlers. Why then no one scored a 400 in that pitch after.

In current generation, players have more T20 mindset, Test match are not even moving to fifth day. I think Lara will hold this record for substantial time.
