Vince steers Sixers home in BBL thriller

English import James Vince has fallen short of a century but delivered the goods at the top of the order to steer the Sydney Sixers to a six-wicket win over the struggling Melbourne Stars.

Marcus Stoinis blasted 52 off 28 balls to lift the Stars to a competitive 5-173 after being sent in at the MCG on Friday night.

But the Sixers surpassed that total with one ball to spare on the back of Vince's unbeaten 91 from 59 deliveries and some late hitting from Jordan Silk.

Silk belted a six from the third ball of Luke Wood's dramatic final over and was then controversially given out caught behind before Dan Christian hit the winning runs.

The result was the Sixers' ninth consecutive win over the Stars - a record BBL period of dominance by one club over another.

It leaves the Stars (2-6) languishing in last place, while the Sixers (5-3) are level on wins at the top with the Scorchers and Thunder.

The Sixers required 36 off the final three overs when Vince belted back-to-back sixes off departing New Zealand international Trent Boult (1-39).

A further 11 runs were required off the last over and Vince should have been run out looking for two off the first ball, but Stars wicketkeeper Joe Clarke missed his first swipe at the stumps with the batter short of his ground.

The massive six from Silk (15 off 10) tilted the match the Sixers' way but he was judged to have nicked Wood's next ball behind and was given his marching orders.

Christian hit his only ball faced off Wood (1-41) for four, steering the Sixers to 4-176.

Vince's season-high innings included nine fours and two sixes as he narrowly missed out on becoming the first player in Sixers history to score a BBL century.

"As a batting group we spoke about how having someone in the top three or four there towards the back end (of the innings) always makes it easier to win games," Vince said.

"Turning some of the 30s and 40s into 70s and 80s can make a big difference, so I was pleased to be there at the end.

"The guys that batted around me took the pressure off nicely because it was the sort of wicket where you felt 'in' but it was gripping a little bit. It wasn't easy."

Stoinis showcased his value as one of the BBL's great entertainers in his first match since announcing a deal to play in the rival UAE T20 competition.

The Stars' premier power hitter blasted seven fours and two sixes, playing the lead role as the Stars took 34 runs off Chris Jordan and Hayden Kerr during the power surge.

"I thought the score was pretty good and we batted well, but it's only really small margins and there's just little things that could go either way," Stoinis said.

"We thought we were going to win the whole time, up until probably two or three balls left."

Sixers quick Sean Abbott (3-31) was the game's only multiple wicket-taker.

The Stars' Campbell Kellaway lost a fingernail while taking a catch to dismiss Daniel Hughes (28) and was substituted out of the match.
