"That definitely crossed my mind, for sure," Joseph said this week. "Obviously, being out for as long as I was, it'll cross your mind. You get a lot of time to think when you're not allowed to do stuff. I thought about it.

"It was a little scary at first," Joseph said. "I got hit and just tried not to think about it. I didn't have any symptoms when I got hit. An inning or two goes by, and all is forgotten. It seems good."
Joseph, the centerpiece of the Phillies' trade in August 2012 that sent Hunter Pence to San Francisco, was considered one of the game's top catching prospects before the most recent concussion, suffered in May.

Joseph's lost season played a small part in the Phillies' extending Carlos Ruiz for three more years.
"Everything seemed like it's coming so fast and I'm moving so slow," Joseph said of the effects of his concussion. "At first, we thought it was just me being out of shape from not playing for a while. Then we realized it was something to do with the brain. We looked into it further."

"Having the drills and starting it now really gets the guys thinking." . . . On Tuesday, the Phillies will play a noon intrasquad game at Bright House Field that will be open to the public. Their Grapefruit League opener will be next Wednesday vs. Toronto. . . . A possum climbed the outfield fence at Ashburn Field and watched the Phillies stretch Wednesday morning. A police officer kept guard until grounds-crew members captured the critter in a trash can. Animal control handled the rest.
