Fast Bowler's Cartel application still pending

Mitchell Marsh continues impressive form with the ball, but FBC leader Mitch Johnson isn't sold just yet

Mitch Marsh's application for membership of Australia's Fast Bowlers' Cartel is still pending, but Australia's quicks might have to cave in soon.

The Aussie fast bowlers occupied the back seats of the team bus during the Ashes, with Marsh's attempts to sit alongside them becoming a running joke in the squad.

As an allrounder, Marsh was considered persona non grata by his fast-bowling teammates throughout the UK tour.

The 24-year-old is now hitting the 140 kph mark more consistently, although Mitchell Johnson isn't quite ready to stop poking fun at his younger teammate just yet.

"He bowled one over and the first ball was at 128(kph)," Johnson said.

"So I said, 'You're still not in'. The rest were at 140. He's not far away.

"I might just cut him a little slack, but I like being the big brother to him so I'll keep giving him a hard time."

Marsh bowled 15 overs in total during the first Test against New Zealand, claiming three wickets and finding himself on a hat-trick on the final day.

While Marsh's recent returns with the bat have been disappointing – he's scored more than 15 just once in his past eight Test innings – his work with the ball has proven his value to the side.

Having taken 3-31 in his recall to the XI at Lord's during the Ashes, he followed it up with 5-86 in the fifth Test at The Oval.

And wicketkeeper Peter Nevill suggested Marsh's added pace was noticeable in Brisbane.

"Mitch Marsh for a couple of balls, but mostly Starc and Johnno," Nevill said, when asked which paceman was hitting the gloves hardest.

"It was great to see ... I'm very happy for him."

Having been forced to wait until his fourth Test to secure his maiden Test wicket, Marsh has welcomed the more bowler friendly conditions he was faced with in England and at the Gabba.

"My first few Tests I was finding my feet I played on some pretty flat wickets," Marsh said of Tests in the UAE and Adelaide late last year.

"Then obviously I played in England where the ball swings and in Australian conditions where the ball tends to bounce more than anywhere in the world.

"With my height hopefully I'll be able to contribute to the team in that sense and just keep improving." 

As was the case in the Ashes, Marsh is still searching for a score of substance.

Adam Voges, who has watched Marsh's progression closely as Western Australia captain, is confident such a knock if not too far away.

"I've seen him play some very, very good innings," Voges said.

"It's wonderful we've got someone in our top six who can bowl like Mitch does. He balances our team beautifully."
