Silk was vital to the successful chase at Marvel Stadium hitting 36 not out from 26 deliveries including a six on the third ball of the final over when eight were required for the win.
It was one of two sixes for the right hander, who also passed 1,000 BBL runs on the night, one of four Sixers to do so. The Sixers made 4/154 in reply to 6/153.
The win put the Sixers equal first on the ladder with the Melbourne Stars with eight games remaining for the men in magenta.
“(We’re in a) decent spot. I think it’s really important obviously to win games early in the season to build confidence, build team morale,” said Silk post-match on Thursday.
“That’s two in a row for us now, that certainly builds a bit of confidence, especially at the start of a three-leg road trip, so yeah wrapped with that tonight.
Silk said there were moments during the run chase that he thought the game had slipped away.
“Yeah definitely, I think whenever you leave it that late, you’re fighting fire with fire there.
“Just wrapped to have got one out of the middle in that last over and thankfully that was enough from there.
“I was pretty calm (at that point), I just knew it was one blow, if I could get one ball out of the middle and get it over the rope or find a boundary, that would be okay.”
The Sixers now head to Coffs Harbour for its first ever regional BBL match on Sunday night against the Adelaide Strikers before boarding a plane to the South Australian capital for the reverse fixture on Wednesday at Adelaide Oval.
“We head up to Coffs Harbour, which is really exciting for us too, to take one of our SCG games up to there is really special,” Silk said.
“We’re looking forward to getting up there tomorrow and getting stuck into it.”
