Their records aren't similar at all. They are the very opposite of similar lol. They were similar after 25 matches, but Waugh has far better career figures in every possible way.

Bowling is somewhat irrelevant though if you're batting in the top six. To do that you need to be able to hold the possie as a batsman, which he can't and which Waugh started to do, steadily improving his batting after around 25 matches.

No doubt he is potentially a better bowler than Waugh was. He's a reasonable 5th bowler but he's never going to get in the team just for his bowling. I don't remember Waugh getting the new ball either, especially later in his career as genuine a part timer.

The only place Marsh's bowling has seemed threatening is in England, for obvious reasons. He's another trundler anywhere else, not terribly threatening nor economical. A big problem for him is that he isn't great in Aus either. Shane Watson was a far better 5th bowler type of batting allrounder.

He should focus on one or the other if he wishes to be a regular in the test team, at the moment he is a "no rounder". Concentrate on either bowling, or batting, instead of being mediocre at both.
