To get this you need your number 11 to score 99 runs or more which can be difficult as they number 11 isn't usually very good at batting.
Set up a test match and set the difficulty to Rookie. Select your team as Australia (or any highly rated team) and select the opponent as Netherlands (or any low rated team) At the coin toss if you win select Bat (if you lose and the opposition bats, you can either play & bowl them out or just exit out and start a new game)
Once your number 11 is in, you will want to save/exit after every over so if they get out before getting to 99, you can just press the home button, quit the game then reload the game and the game will pick up before they're out. If the number 10 is batting, take a single to get the number 11 on strike then try to take a single off the final delivery.
I found trying to cut behind resulted in being caught alot so drives to covers, pull shots and cutting square will probably be your go to shots. You can usually hit spinners for 6 relatively easily either by charging down the wicket with
,
and
together or just a lofted shot with
, you usually want to start your move just before the ball hits the wicket.
Then just keep batting and save/exiting and re-loading saves until the achievement pops.
