Zack Greinke, who is operating without an agent, remains open to discussing a contract extension with the Brewers. He is entering the final season of a four-year, $38 million contract he signed back in 2009. "I'll talk to them about it," Greinke said when asked about a possible extension. "I don't really want to talk to anyone else about it. But I like the business of baseball. It's exciting for me. It's not like I plan on being my agent, but it is exciting being able to know what's going on behind the scenes."
