A more fine-grained example of a task switch is the use of bowling variations, which often demand drastic changes in motor coordination. With disciplined practice, good bowlers can disguise variations and switch between deliveries with few flaws in their execution. Bowlers can train themselves to minimise or eliminate the effect of these switch costs between variations by bowling different types of deliveries a lot in net sessions. But in high-pressure situations, switching between different balls, which was so effortless in the nets, can suddenly prove challenging to execute. This is seen in the death overs of just about any T20 game when an intended yorker or flighted, wicket-seeking delivery becomes a full-toss.
Research shows that time pressure itself (caused by a nervous bowler hurrying their rhythm, for instance) amplifies the effect of a switch cost. Pressure impairs performance by making alternative plans look more attractive, forcing switch costs and amplifying these costs by causing bowlers to rush
Harshal has built his name on his death bowling, as was borne out by the fact that the match was not already won in the four balls preceding the failed run-out attempt. Like Dwayne Bravo, his success in this phase of the game rests on his signature dipping, slower yorker. Both these bowlers’ resounding success in the IPL (three purple caps between them) can be attributed not just to the difficulty batters have in hitting their signature deliveries but to how even the failed execution of this delivery – the dipping full toss – is difficult to hit. These players are not necessarily beasts under pressure; their success rests on even their “mistakes” having utility. In other words, just because Harshal can be effective at the death, that does not necessarily say he is invulnerable under pressure and to pressure-mediated switch costs.
At this point perhaps Harshal simply plots another yorker in light of the relatively tighter field and the conditioning imposed by the previous delivery, which was short. As he gets into position for his run-up, he may well have got into “dipping yorker mode”, a rehearsed, finely tuned choreography – saunter, sprint, leap, release – that he has performed countless times in the nets and in match situations like this one with success.
At some point during this sequence of actions, he catches a glimpse of intent from Bishnoi to run early, or perhaps he doesn’t see Bishnoi but quickly decides that there is no risk at this point in attempting a run out. Either way, given that he has already begun his bowling action, there is difficulty inhibiting dipping-yorker mode and therefore difficulty in efficiently adopting “non-striker-run-out mode”. As a result, an execution error occurs and the ball is declared dead.
What if the run-out attempt was premeditated? The underlying switch-cost logic still holds. In this case, Harshal is aware that Bishnoi may leave his crease early in light of the game situation. In order to sufficiently fool Bishnoi into believing the ball will be bowled, Harshal launches into a general “bowling mode”, replicating most of the choreography mentioned above. In trying to realistically bait the non-striker, he devotes his attention to bowling mode. This makes the eventual inhibition of this mode difficult and subsequently leads to a failure in executing the secondary non-striker-run-out mode. The magnitude of this cost is perhaps amplified further by the implicit time pressure caused by rushing when nervous. In a sense, the razor-sharp focus on execution that preceded the run-out attempt amplified its error rate.
What distinguishes the run-out attempt is that it is likely not something Harshal has practised to the extent he has practised actually bowling. More specifically, it is unlikely that coaches ever have had players practise disengaging from their run-up for a purpose beyond just stopping. As a result, most players likely do not have the required training required to switch without cost between the task of bowling and the task of running out the non-striker.
This confusion within the cricket community – which exists despite how clear the laws of the game are on the issue – may discourage players from training for a legitimate form of dismissal, leading to errors in execution during the moment of truth. Harshal’s own hesitation reflects the hesitation many in cricket have towards non-striker run outs generally. An event like this botched non-striker run out can indirectly serve as a reminder that teams need a full commitment to the laws of cricket, not to some nebulous “spirit of cricket”. This sentiment should not just be reflected in words and thoughts but also in training regimes and strategies, just like with any other element of cricket play.
