MOTM gotten wrong?

Things just don't seem to add up after last night's ODI between Australia and South Africa.

AB scored 80 off 87 ballls (strike rate of 91.95) whereas Kallis made 70 of 86 balls (strike rate of 81.39)

Then Ab took an awesome catch and Kallis did his usual bowling lot of 4 overs for no wickets.

BUT then the Man of the Match was given to Kallis?? Hmm Interesting.
