London-based sports psychologist Victor Thompson explains. "The main risk is that the bowler will interpret the sixes as evidence that he has failed as a bowler," he says. According to the sports psychologist, a bowler should focus on the challenge and not the threat of the situation to prevent from crumbling psychologically.
"He should analyse his delivery and look for ways to test and beat the batsman. He must keep his body language confident and positive: upright, purposeful, chest high. He should also recall similar situations before where he has had success and shown grit against a challenging batsman. Other techniques can also help but these can give most bowlers a boost," Thompson says in an email interview.
Florida-based performance psychologist John F Murray compares the event to a pitcher getting hammered in baseball. "The effect depends entirely on a player’s experience, self-confidence, maturity and resilience. If a player is high in these factors then catastrophic failure has little effect and the player usually recovers well and may even return with increased confidence and focus," he says.
