Sussex's promotion hopes ended abruptly today as Derbyshire ended a run of three championship defeats with a 181-run victory.

Chasing a tough target of 345, Sussex folded against a depleted Derbyshire attack and were dismissed for 163 with Fynn Hudson-Prentice, Anuj Dal and Matt Critchley each taking three wickets.

Ollie Robinson had given them hope with 5-88 and Reece Topley claimed 4-58 after Derbyshire lost their last eight wickets for 77 to be bowled out for 437 but that was soon snuffed out as the home side celebrated with more than 24 overs left in the day.
