The Philadelphia Phillies and local police are investigating an incident in which a fan at Citizens Bank Park threw a beer bottle from the stands at Ryan Howard on Saturday.

Howard was walking back to the dugout after a pinch-hitting appearance when the bottle landed near his feet.

The once-powerful slugger is hitting .151 this season and making $25 million in the first year of his five-year contract.

"I've done too much in this town to have that kind of stuff," Howard said Sunday. "If you want to yell out 'You suck,' that's whatever. But when you start throwing stuff, that's when stuff gets personal."

He said he didn't see the bottle in the air but noticed it after it landed near his feet.

"I don't play that. To me, that's crossing the line. It becomes a security issue. It's not necessary. That stuff infuriates me," Howard said.
