FYI, it's not just Yahoo that's incorrect. Many websites share inaccurate info. Many website "journalists" leave a lot to be desired in the accuracy and fact checking parts of their job. One person makes an error and other writers and websites repeat it. Covers also has that statement about Hampton having a 5.1 ERA vs. Phil last year, then provides stats that proves that statement is wrong/
From Covers:
Since last July, Hampton is 12-1 in 16 starts. In his first two outings this year, the veteran left-hander has allowed just two runs over 14 innings. He did not walk a batter in his last outing, an 11-2 victory over Washington on Monday.
He'll try to beat a Phillies team that treated him very poorly a year ago. Hampton went 0-2 with a 5.12 ERA in three starts against Philadelphia in 2004. Phillies third baseman David Bell is hitting .350 (14-for-40) with two doubles off Hampton in his career.

Caveat Emptor: Don't believe much of what you read on varioius websites. Check multiple sources for accuracy. Good luck to all on both sides of this one.
