I got this achievement playing as a test match with England versus Kenya. Using the save method, after about 10 overs I got Strauss and Cook up to fearless, and by this stage the bowlers were timid.
Ideally what you want is one of their medium paced bowlers to come on, where he drops the ball short. I did not try this acheivement until the medium pacer did this with his first ball (they seem to do it evry 2-3 overs when timid).
The shot I found best in this scenario was a paddle shot (holding the controller at 2 'o' clock), so its not a hook shot, but the opposite. If you pull the left trigger so its a back foot shot, and push B just before the ball lands on the pitch, you should paddle it to the right of the slips for 6. This seemed a lot easier than hooking it (9 'o' clock, where 1 in 4 would go for 6). Then just save, and rinse and repeat. Thankfully, the bowler kept just dropping it short for the over, which he will hopefully do.
