It's 2 tests, rescheduled from earlier on following the Tsunami.

Fleming will do OK against Vaas and Co. Vaas is no McGrath and Sri Lanka also don't have a Brett Lee. It's a new challenge for him and he will approach it differently mentally.
Besides, the openers shouldn't be knocked over so quickly and he should be able to go in when the pitch is good and the bowlers are ripe for the picking! No 4 is his position.
Plus, he was in good form until he played Australia. I can't see why he can't regain that now that Australia have gone.
