With their play-off hopes dashed, Marsh said his team can still pull the rug from the rivals'' feet and spoilt the party of other teams in their remaining two games.
"We can''t make the finals, which is disappointing. All we can do is stop other teams from getting there. We want to finish in the best possible way we can, with two wins," Marsh said ahead of Pune''s penultimate round-robin clash against Kolkata Knight Riders at the D Y Patil Stadium in Navi Mumbai.
"The inconsistency with our batting has been disappointing. We just have not batted well enough. I think about five times we have been four down for 40 runs. It''s very hard to win a game from there no matter how well the bowlers bowl.
"We have very good players. We have been a little bit unlucky with injuries. We lost some key players whereas other teams have kept their guys going," the Australian said.
Marsh pointed out that Pune lost Ashish Nehra and Angelo Mathews through injuries before the start of the tournament and then missed out on Graeme Smith and Tim Paine, who got hurt during the course of the event.
"We did not have Ashish Nehra and Mathews from the start.
Those were two players we wanted to buy at the auction. Callum Ferguson came late (after playing for Australia). We lost Mathews. We lost (Greame) Smith. We also lost (Tim) Paine.
They were three of our batters who would have been in the top six and we lost them through injuries," he said.
But these were not good enough excuses for the poor run of the team in the tournament, that saw Pune slump to seven losses in a row after starting off with two straight wins, he conceded.
"No excuses as we have good players in there, but have not scored enough runs," Marsh said.
Marsh wants his main batmen like captain Yuvraj Singh and Jesse Ryder to take full advantage of their starts and go on to make 60-plus runs in the remainder of Pune''s IPL campaign this season.
"Hopefully tomorrow Yuvraj can go in there and turn his 30s into 60-plus and Jesse Ryder can go on and convert those starts into big scores like (Adam) Gilchrist, like Shaun (Marsh), like (Sachin) Tendulkar.
"Teams like Chennai are on top because guys like (Michael) Hussey and others are getting not 30s and 40s but 70s and 80s. That''s what we have failed to do," he said.
The former Australian Test opener, however, did not find fault with the leadership of Yuvraj. .
