Rilee Rossouw produced another standout performance from South Africans playing in England’s T20 Blast.

Rossouw followed his 67 off 29 balls earlier in the week with a blistering 74 from just 29, but failed to save Somerset from their first defeat of the season as Sussex enjoyed a 47-run success on Wednesday.

His assault was relentless as he charged to a 17-ball half-century with a pulled six off Steve Finn.

In the first innings, fast bowler Marchant de Lange bagged two wickets for 56 runs while former Proteas spinner Roelof van der Merwe finished with 1-30.

Fellow SA-born Netherlands international Colin Ackermann led a fightback with a captain’s knock of 33 for Leicestershire in a 42-run defeat against Northamptonshire.

The South African left-hander blasted five sixes and eight fours but he lacked any meaningful support.

Skipper Dane Vilas chipped in with a handy 34 runs off 22 balls in Lancashire’s 17-run victory over Derbyshire.

However, an unbeaten 59 by Leus du Plooy showed why Derbyshire have already notched two Blast wins this season.

George Linde claimed figures of 1-27 and scored six as Kent lost to Gloucestershire by six wickets.
