Sydney Sixers 142 for 2 (Philippe 66*, Patterson 32) beat Brisbane Heat 138 for 9 (McSweeney 34, Dwarshuis 4-32, Kerr 2-19) by eight wickets

Sydney Sixers have maintained their unbeaten start to the BBL with an eight-wicket demolition of Brisbane Heat.

Philippe was all class in his 17th BBL half-century and was the rock on which the run chase was built as Sixers reached their target off the first ball of the 17th over.

"It doesn't quite get revenge for what happened last year but we are a step closer to getting into the final and going a step further this year," Dwarshuis told AAP. "It's been a really good team start to the season. With the bat and ball everyone has contributed.

"Josh is in great touch and it makes a big difference when guys at the top of the order are scoring runs. We are building pressure throughout the innings with the ball. All the bowlers are doing their job and I am the one getting the wickets for now. It is nice to be getting the accolades."

It was Silk's 81st catch in the BBL but his 82nd was from another planet when he sprinted and dived full length to snare the ball in his right hand millimetres from the turf to dismiss Jimmy Peirson, also at midwicket.

The victory took Sixers to eight points after four matches, four clear of five other sides including the defending champions Heat, who have now lost two in a row.

Sixers were far superior in the field where Silk set the bar high and his teammates all lifted. Heat bumbled in the field. Munro and Paul Walter were left looking at each other as the ball bounced between them when Philippe skied a swipe early in his innings.
