Siddle stars on record-breaking night for Somerset

Ageless Australian seamer Peter Siddle has claimed his best T20 figures on English soil as Somerset hammered Derbyshire by 191 runs to book their spot in the tournament's finals day.

It was the third largest winning margin in the history of T20 cricket (and biggest in domestic cricket) with Somerset's colossal 5-265 the fifth highest total ever posted from 20 overs.

South African power-hitter and Big Bash draft nominee Rilee Rossouw was the main destroyer with 93 from just 36 balls as the hosts' batters cashed in at Taunton in the fourth quarterfinal.

The left-hander smashed seven sixes and eight fours as Somerset scored 185 runs at 16.81 per over from the last 11 overs of their innings.

Former Brisbane Heat import Tom Banton also hit 73 from 41 balls at the top of the order while Tom Lammonby, one of the Hobart Hurricanes BBL|11 overseas players, crunched 31 off nine balls to end the innings.

Leg-spinner Mattie McKiernan now owns the unfortunate title of most expensive figures in the T20 format, conceding 82 runs from his four overs.

Rossouw blasted 36 runs alone from McKiernan's fourth over and 15th of the innings (five sixes, a four and a no ball) as his spell eclipsed Sarmad Anwar's 0-81 while playing for Sialkot Stallions against Lahore Lions in 2011.

There were no such problems for Siddle who conceded a miserly 10 runs from two overs with Derbyshire never in the hunt of pulling off a record chase.

The Tasmanian paceman removed opener Luis Reece and Leus du Plooy in his first over before having fellow Aussie Hilton Cartwright (10) caught at deep midwicket from a miscued pull shot in his second.

The 37-year-old now has 17 wickets from his 10 Blast matches in 2022, continuing his superb T20 form after being the BBL's leading wicket-taker last season with 30.

Right-arm quick Ben Green also collected three wickets as Derbyshire were bundled out for 74 in 11.2 overs.

Siddle will go head-to-head with Tigers teammates Ben McDermott and Nathan Ellis next Saturday when Somerset face Hampshire in the second semi-final at Edgbaston, with the winner to play Tim David's Lancashire or Yorkshire, who clash in the first semi-final at the same venue that morning.
