There have been more than 25 umpiring errors in the 59 games played so far this IPL. Of those, 13 were blunders that did not need replays to spot. Four of those went against Mumbai Indians while five were in favour of Kolkata Knight Riders. Among the umpires, Anil Dandekar made the most howlers - three - while Nitin Menon, whom the BCCI nominated last year to be part of the ICC's international panel of umpires, C Shamshuddin and S Ravi made two each.

Rohit Sharma declared out off Washington Sundar, Mumbai Indians v Rising Pune Supergiant

As well as young Washington bowled in his first IPL playoff game, a giant stroke of luck played its part in embellishing his figures. Rohit tried to paddle an offbreak in the direction of short fine leg but failed to execute. Before hitting the pads, the ball deflected off the inside edge, a deviation that was visible to the naked eye. Umpire Shamshuddin didn't think so, and the Mumbai Indians captain was, not for the first time in the tournament, at the receiving end of a bad decision.

David Warner declared not out off Ankit Soni, Sunrisers Hyderabad v Gujarat Lions

Sunrisers were chasing and the match was in the balance when Soni had Warner edging to Dinesh Karthik. The deflection was so obvious that Karthik did not bother to appeal. Anil Chaudhary was the umpire and his decision was a confident "no". Replays showed a huge edge, and Warner took his side to victory in a crucial fixture, remaining unbeaten on 69.

Yusuf Pathan declared not out off Yuzvendra Chahal, Kolkata Knight Riders v Royal Challengers Bangalore

With just three runs to get, Yusuf Pathan poked at a wide one outside off stump, and the ball took an under-edge en route to Kedar Jadhav's gloves. Chahal, and the fielders around the bat, pleaded with umpire Anil Dandekar only to be met with a firm shake of his head.

Robin Uthappa declared not out off Basil Thampi, Kolkata Knight Riders v Gujarat Lions

For the second time in the tournament, Uthappa was given a reprieve. Thampi struck him in front of middle with a full ball that was going to crash into leg stump, but umpire Nitin Menon did not even seem to consider giving it out. Instead, he moved quickly to get into position to adjudicate a possible run-out. The ball had hit Uthappa, who was batting on 71, on the back foot, which made it more puzzling that the umpire had dismissed the appeal so quickly. Luckily for Lions, the decision didn't prove too costly. Uthappa added just one more to his score.

Manan Vohra declared not out off Mohammad Nabi, Sunrisers Hyderabad v Kings XI Punjab

Vohra played one of the innings of the tournament against Sunrisers, getting 95 off 50 balls, but he should have been out when he was on 32. Nabi hit him on the pad in front of off stump, and it looked as though the ball would hit middle. But Dandekar reacted to the appeal by suggesting there had been an edge. Replays confirmed there wasn't one.

Robin Uthappa declared not out off Bhuvneshwar Kumar, Kolkata Knight Riders v Sunrisers Hyderabad

Uthappa got the rub of the green as early as his first ball, when he edged a Bhuvneshwar Kumar outswinger to the keeper. Dandekar, though, missed it. Uthappa went on to hammer 68 off 39 balls.

Kedar Jadhav declared out lbw off Varun Aaron, Royal Challengers Bangalore v Kings XI Punjab

Kedar Jadhav was Royal Challengers' in-form batsman going into this game. At 22 for 2, they needed him to anchor the innings along with AB de Villiers, but Varun Aaron's indipper struck him high on the pad. Jadhav, while not a tall man, was jumping at the point of impact. Replays showed the ball was going over the stumps.

David Warner taking strike after hitting a boundary off the last ball of the previous over, Sunrisers Hyderabad v Mumbai Indians

Warner had glided Jasprit Bumrah to the third-man boundary off the final ball of the sixth over. As Mitchell McClenaghan ran in to bowl the first ball of the seventh over, Warner was on strike again. This gaffe - concerning a basic aspect of the game - was arguably worse than the rest. Umpires Nitin Menon and CK Nandan had been caught napping.

Carlos Brathwaite declared not out off Yuzvendra Chahal, Delhi Daredevils v Royal Challengers Bangalore

Daredevils needed 45 from 33 when Brathwaite was pinned in front of off and middle, having failed to pick up a flatter googly. Umpire Virender Sharma was unmoved by a pleading Chahal, but the error didn't cost Royal Challengers as Chahal bowled Brathwaite next ball.

Rohit Sharma declared out lbw off Sunil Narine, Mumbai Indians v Kolkata Knight Riders

Mumbai received their second poor decision in two overs when Rohit was adjudged lbw despite getting a big inside edge before the ball struck his pad. Narine had been bowling legbreaks throughout the over and foxed Rohit with an offbreak. Umpire Nandan gave it out immediately, and Rohit stood at the crease shocked. When asked about decisions going against Mumbai, Parthiv Patel refused to comment after the game, citing the heavy fines in place.

Jos Buttler declared out lbw off Ankit Rajpoot, Mumbai Indians v Kolkata Knight Riders

In the previous over, Buttler received his second howler of the tournament, having got off to a blazing start in a chase of 179. Ankit Rajpoot swung a low full toss into the right-hander. Buttler missed it, and while the appeal was vociferous, the ball was sliding down the leg stump by a distance. This time, it was Menon at the centre of the howler.

Kieron Pollard declared not out off Imran Tahir, Mumbai Indians v Rising Pune Supergiant

Mumbai received a rare slice of luck when Pollard was rapped on the pad by Tahir; the ball looked likely to have crashed into the stumps. The doubt was whether the ball had hit bat or pad first. Umpire Ravi thought it was the former, while replays showed it hit pad first. Pollard survived and went on to make 21 more. Rising Pune wicketkeeper MS Dhoni signalled for the DRS in jest, and was reprimanded after the game.

Jos Buttler declared out lbw off Imran Tahir, Mumbai Indians v Rising Pune Supergiant

Buttler had smashed 38 runs off 18 balls, including 12 in the previous over, before he played all around a length ball that skidded on. It had taken a massive deflection off his bat before rapping him on his front pad. Umpire Ravi, though, had his finger up before Pune's fielders had completed their appeal.
