The 12-year-old struck 55 as Chipps' 3rd XI recorded a resounding 106-run Sussex League Division 11 West victory at Littlehampton 4th XI.
Oli is Chippingdale's under-13 skipper and made his adult section debut earlier in the campaign.
The club are willing to give talented and capable colts players a go in the adult section, with Oli rewarding the faith shown in him by hitting a half-century a month before he turns 13.
It is thought he has become the youngest player to hit a half-century in adult cricket. Do you know of anyone younger to do so? If so, email [email protected] with information.
