In this World Cup, Imad Wasim has excelled at stifling batters with deliveries that slide into them

Karthik Krishnaswamy10-Nov-2021He takes the new ball for Pakistan, bowls with his left arm, and swings it into the right-hander. He’s a key component of what is arguably the most rounded attack in this T20 World Cup, and how he goes in the powerplay could prove a decisive factor in Pakistan’s semi-final against Australia on Thursday.We could be talking about Shaheen Shah Afridi, but we’re not. We’re talking, instead, about the bowler Afridi might be if he bowled at 90kph rather than 90mph.Imad Wasim has played more than 100 games for Pakistan, but cricket is yet to catch up with what he really is. His introduction to the bowling attack continues to be accompanied by TV graphics that describe him as a purveyor of slow left-arm spin, or, even more egregiously, left-arm orthodox.Related

The left-arm orthodox spinner’s stock ball is bowled with the seam pointing to first slip, and is delivered with a mixture of overspin and sidespin. It climbs above the batter’s eyeline, then dips, grips, and turns away from the right-hander (watch this over from Bishan Bedi if you prefer things explained visually). There is scant evidence of Imad ever having bowled such a ball in his international career.Instead, his go-to ball is the arm ball, delivered with his index finger imparting backspin, and with the seam upright and canted towards fine leg. It swings in the air, into the right-hander, and skids off the pitch, hurrying on with its initial angle.The arm ball is a celebrated part of the fingerspinner’s classical repertoire, and Bedi was renowned for it (watch Kim Hughes get his comeuppance), but he probably never bowled six of them in an over, as Imad often does.Slow left-arm inswing, then, is probably the most accurate label for what Imad does, even if Imran Khan would prefer that you called him a – Pakistani slang for a bits-and-pieces player.And while he might take it to an extreme, Imad represents a widespread tendency among fingerspinners in T20 cricket now. When they bowl to their opposite-hand batter (left-arm spinner to right-hand batter, offspinner to left-hand batter), they predominantly look to bowl balls that go with the angle – usually into the stumps from around the wicket – and only occasionally look to turn the ball away from the bat.The sliding-with-the-angle ball can be the arm ball or a number of other variations, the most common of which is the undercutter. This is delivered in exactly the same way as the offbreak or the left-arm spinner’s away-going ball, but with the wrist cocked back rather than upright at delivery. When the bowler does this, the circle of the seam spins like a slightly tilted frisbee. This produces natural variation, with the ball tending to turn if it lands on the seam, and to skid on with the angle if it lands on the leather.Kshiraja Krishnan/ESPNcricinfo LtdMitchell Santner’s contest with Virat Kohli in Dubai (ten balls, five runs) was probably the high point of the undercutter at this World Cup. Time after time, Kohli kept looking to make room to hit Santner through the off side. Time after time, the ball drifted in from wide of the crease, and kept going with the angle, often stopping on the pitch too, making Kohli hit too early, with too much bottom hand, towards the bowler or mid-off rather than through the covers as he intended.No matter what inward-sliding variation the bowler employs, the idea behind it is the same. In white-ball cricket, and in T20 in particular, the batter’s most precious resource is room to free their arms, whether to hit with the spin or against it. Denying the batter room can limit their scoring areas drastically.This becomes particularly important when the spinner bowls in the powerplay, with only two fielders outside the 30-yard circle. Give the batter room and they can hit the ball wherever they please. Cramp them successfully and they’re forced to manufacture risky ways of finding the boundary or to be content with singles to the leg-side boundary riders.Apart from room, the arm ball and undercutter, which lack the overspin of the traditional turning ball, also deny batters the bounce they rely on for lofted hits.”If anything, it’s going to skid on or stay slightly lower, so it’s more difficult to get underneath the ball and hit it in the air,” says Bazid Khan, the former Pakistan batter who’s part of the TV commentary team at the T20 World Cup. “And also, with the arm ball, you can increase your pace and bowl it much flatter or quicker as you like. If you want to turn the ball, and the pitch is not a turner, you can’t really bowl into the pitch as quickly as possible and then get it to turn.”Triple threat: the arm ball rushes the batter, cramps them for room and denies them bounce•ICC via GettyAt this World Cup, the pitches in the UAE have been on the slower and lower side, which has only made it harder for batters to attack the ball that slides into them.”A person like Imad Wasim, who’s going to predominantly swing the ball into the stumps, on pitches where the ball is not coming onto the bat, it’s almost impossible to hit him down the ground, because he bowls it quite quickly and he bowls short of a length,” Bazid says.”When he’s bowling in the UAE or on pitches where the ball is not coming onto the bat, where do you risk hitting him? You can’t really get to the pitch and hit him down the ground, you can’t trust the ball to come onto the bat, and if you go leg-side-ish or if you try to slog-sweep, then you run the risk of getting out lbw, because it’s across the line and it’s quick, and if you mistime it or if it’s a half-hit, you’re gone, so it restricts the scoring areas a lot.”That conditions in the UAE have suited Imad’s bowling is reflected in his numbers. He has an overall economy rate of 5.23 at this World Cup, and within the powerplay it’s a hugely impressive 5.66. Fingerspinners at large have flourished in the tournament. They’ve conceded a combined 6.61 per over at this World Cup; never before have they been so frugal. And only in 2009 have they returned a better average than their 22.83 in this edition.
