Sixers go for Thunder's jugular in BBL

The Sydney Sixers are promising to go for the Sydney Thunder's jugular ahead of their monster BBL showdown.

The match, which is expected to attract a crowd of 30,000 at the SCG on Saturday, will have huge ramifications for both sides.

The Sixers are second after their Ben Dwarshuis-inspired eight-wicket romp over the Adelaide Strikers on Tuesday and are in contention to host a final for the first time since 2014.

While the Thunder are fifth, one point behind the Melbourne Stars ahead of their meeting with the Melbourne Renegades on Wednesday night.

One loss in their final three games could end their season.

Despite having plenty of mates in the Thunder line up, Dwarshuis said there was no room for sentiment and they wouldn't think twice about driving a nail into their coffin.

When asked if he had any sympathy for the Thunder, Dwarshuis said: "Absolutely not.

"We'll be going out to (end their season). Locking in a semi position and also knocking them out. It's all just added incentive."

Dwarshuis now has 12 wickets for the tournament while teammates Sean Abbott (18), Steve O'Keefe (17) and Tom Curran (16) all sit in the top five wicket-takers for the tournament.

He took 3-7 - including the key wickets of Jake Lehmann (46) and Jono Wells (23) - as the Strikers were restricted to 8-124 from their 20 overs, before Moises Henriques and Daniel Hughes half centuries guided them home.

Dwarshuis would have finished with 4-6 had James Vince been able to hold onto a difficult chance - in which he flew into the air and attempted to grab the ball two-handed after Michael Neser smashed it to him at cover.

"I made a little sly comment as (Vince) was padding up," Dwarshuis said.

"But in the end it was a great effort to get there and save three runs and give a little bit of momentum towards us. I can't be too hard on him. It would have been spectacular. It either sticks or they don't."
