Kimber came to wide attention for his County Championship innings for Leicestershire against Sussex on 26 June 2024. Coming in at 144 for six with Leicestershire chasing 464 on the final day, Kimber scored 243 from only 127 balls. His innings featured the fastest double-century (100 balls) and most sixes (21) ever in the County Championship. He also hit Ollie Robinson for the most expensive over in first class cricket history[a]: Kimber scored 37 runs from six legal deliveries and three no balls – the total cost of the over including the extras was 43. Kimber was the last Leicestershire batter dismissed, having taken Leicestershire to within only 18 runs of a victory that had earlier seemed impossible.[6]
Notes
^More expensive overs have been conceded, but aren't counted as records because the bowler was trying to give away runs to contrive an unlikely result. See Wikipedia's list of first-class cricket records: most runs in an over for further details. Robinson, an international bowler, was in this case earnestly trying to get Kimber out.
