On a slow, unforgiving pitch at Chester-le-Street, England found a way to win without their usual pyrotechnics — a sign, perhaps, that a team once defined by spectacle is learning the quieter virtues of resilience. Will Jacks, a man asked to do more than expected, answered with both bat and ball, steering England to a 89-run victory over Sri Lanka and a tenth consecutive white-ball win over the same opponents. It is the kind of result that doesn't dazzle but endures, and in the long arc toward a World Cup, endurance may matter more than brilliance.
