Marsh is priced at 11/2 to win the man-of-the-match in the BBL11 final but there is a chance he will have to do it with the bat following a scare with his hamstring.
Marsh has arguably been star of the tournament following some devastating form with the bat and the Scorchers will just be delighted to have him available as they bid to knock over the Sixers.
Scans have shown no serious damage to the hamstring but the Scorchers could be reluctant to ask Marsh to run in to bowl at full speed for fear of him aggravating it.

Much could depend on whether Perth bat or bowl first and the state of the game, but Turner says the important thing is Marsh will be in the side.
"He’s definitely going to play,” Turner told reporters on Thursday. "I’m not sure about bowling but he’s definitely going to play as a batter at least, as a bare minimum.
"We’ve seen how much of an impact he’s had. Stats show that you don’t need to run as many twos at Marvel Stadium and there’s a high percentage of boundaries hit here.
"Not that Mitch can’t run, he’s moving pretty well. I saw him chase my daughter at the park the other day so he’s moving OK."
Turner is not too concerned if Marsh cannot bowl as he believes he has plenty of other options heading into the final.
"We saw with Mitch not bowling in our last final that we were fine with five bowlers and I can still bowl," Turner added.
"We haven’t finalised our team so we don’t quite know the make-up of the final XI yet so the more options, the better but we’ve also played plenty of games with five bowlers."
Looking forward to the week aheadr
