Michael Wilbon said it best on PTI:
We begin with a man hitting his 600th home run–without his name attached to steroids, without a scandalous trainer, without a federal investigation, without perjuring himself before Congress. Jim Thome hit his 599th and 600th home runs […] and becomes only the 8th man ever to hit 600–only the 5th without steroid suspicion. Aaron, Ruth, Mays, Griffey, Thome–that’s it, that’s your list.
