R.A. Dickey says that if he doesn't reach an agreement on a contract extension with the Mets before the 2013 season, he'll likely walk after the season.

"It's hard," Dickey said. "When people say it's business, it's not personal, well, that just means it's not personal for them. I'm hoping it ends up in a good place, but also in the back of your mind you think it may not. That's sad."

He is under contract for the 2013 season at $5 million, but the two sides have discussed an extension and trade rumors have swirled.
