Answer
It is fair.
Work Step by Step
We find the number of hits per at bat to find how well each hit. For Freeman:
$$ =\frac{168}{600} \\ = .28$$
For Suzuki, the ratio is:
$$ =\frac{126}{450} \\ = .28$$
We see that the ratio is the same, so it follows that it is fair for her to argue that they were equally good hitters.
