Captains Cook, Clarke reach the 100 mark together

In a stat among stats for a sport which places extraordinary value on centuries and numbers, opposing captains Michael Clarke and Alastair Cook will each earn their 100th test caps in the third Ashes match of the series.
Clarke's Australian team leads the five-test series 2-0 and is hoping to regain the Ashes in Perth. Cook's team has won the past three Ashes series but after going through a year without defeat, has suddenly slumped to back-to-back defeats in this series.
Understandably both players will therefore put more emphasis on their teams, but the coinciding hundreds warrant attention.
The 32-year-old Clarke made his debut in India in 2004, late in Australia's prime period in modern cricket, and has scored 7,940 runs at an average of 52.58

Cook, who will turn 29 later this month, made his debut in India in 2006 and has scored 7,883 runs at an average of 47.20, the kind of return that his deputy believes already puts him on the path to greatness.
"I don't know the records that he is about to break but there are going to be a few of them," England vice-captain Matt Prior said Wednesday. "He will be probably the greatest England cricketer.

"In my mind there is no doubt about that and from a leader point of view there is no other man I'd want leading us on to the field, because he leads from the front and leads by example and I expect he will do exactly that in this game. A massive congrats to him for playing 100 games - incredible."

Australian fast bowler Mitchell Johnson wants to terrorize the England batsmen for the third time in the series to deliver his skipper a fitting 100th test.
"It's a phenomenal effort to make 100 tests," Johnson said. "It's a lot of days out in the field and a lot of heartache that goes with it, but also a lot of happy times as well, like we're going through at the moment.
"He'll definitely be feeling a bit. He'll be nervous and I'm sure excited at the same time.
