Melbourne Stars 155 for 6 (Cartwright 47*) beat Sydney Sixers 154 for 8 (Vince 83, Mir 3-19, Rauf 3-38) by four wickets

Chasing 155 for victory against the previously undefeated Sixers, Stars hauled in the target with three balls to spare to claim the four-wicket win.

But they were forced to do it the hard way after cricket's controversial clean catch rule reared its ugly head early in the chase.

Replays, however, showed the ball was planted onto the ground as Henriques landed, hurting his left shoulder in the process.

Cricket's laws state a catch cannot be claimed until the fielder has full control of his body and therefore the ball cannot touch the ground in that time.

Former Sixers marquee player Brett Lee admitted in Fox Cricket's commentary the ball "clearly" touched the surface and was not out according to the rule book.

"I actually think it's out," Rogers said after the game. "Moises controlled it and took it beautifully, but I suppose it's just a grey area with what's happened in the other game with Mitch Starc's one.

"It's obviously a hard one to be on the rough side of it, but at the end of the day I've hit a bad shot and he has taken a nice catch so it probably is out."

"As I was looking through the vision, I did not have conclusive evidence to say that there was no fingers under the ball," Polosak told Seven.

And while Webster was caught at long on for 35 trying to take down Sean Abbott, Cartwright was able to get Stars home with an unbeaten 47.

His wickets included Henriques when he deceived the Sixers captain and had him stumped, before a quicker ball drew Jordan Silk's edge later in the over.

But when he was run out by a Maxwell direct hit, Stars were able to keep the Sixers to 14 runs from a crucial final two overs of the innings.
