The 40-year-old was a notable absentee from the opening four games of the season, and he revealed the reasons why after his star knock against the Scorchers.

"I did both my calves over the last four or five months, so it's been tough work to get through that," Marsh said. 

"My first one I did was just getting back from Bali - just doing some run-throughs. 

"So I had the left one (injured) and then that was coming good. And then I did my right one. 

"So yeah, it was frustrating knowing that this was going to be my last season.

"I'd be lying if I said I didn't (worry about the possibility of not making it back).

"It hasn't been all smooth sailing, but it's nice to be back here now and hopefully I can string a few games together and get a few wins."

Marsh has become accustomed to starring straight after injury setbacks, and it was no different in front of 42,226 fans at Optus Stadium.

"What gave me a bit of confidence was it was pretty similar to last season - I played no cricket up to Big Bash really," Marsh said.

"So I fell back on that. But I certainly felt pressure today. It was probably one of the most nervous times I've had before a game."

As for his looming retirement at the end of the season?

"I haven't thought about it too much," he said. 

"I've got a job to do, and that's to finish off really well here. 

"I'm here to contribute and win games of cricket."

The Renegades sit last on the table with four losses and a no-result from five games.

The reduced 10-match season means the Renegades face an almighty battle to reach the finals, but Marsh isn't giving up hope.

"I think we proved it last year (that we can storm home)," Marsh said. 

"We know that the margin for error now is very, very small. 

"We probably need to win all our games.

"But with a group that we've got, we've got every chance to do that."

The Renegades will be back in action on Friday against the Adelaide Strikers.
