Milwaukee Brewers general manager Doug Melvin was working the phones Thursday night, talking to multiple clubs about possible trade scenarios involving right-hander Zack Greinke.
Melvin declined to name the teams pursuing Greinke, but the Texas Rangers, Los Angeles Angels, Atlanta Braves and Chicago White Sox were believed to be making the biggest pushes.
Greinke is scheduled to pitch again Sunday for the Brewers against Washington, but Nationals manager Davey Johnson made it clear that he didn't expect to be facing Greinke this weekend.
"I'd be real surprised," he said. "I know in the past if a ballclub's intent on making a move, you're not going to pitch him two days before the deadline. (Preparing to trade Greinke) is probably one of the reasons they've got eight pitchers in the bullpen.
"A club would probably like to put him right in their rotation, and you don't want to do anything to hurt him. Valuable trade chip."
Melvin told the Milwaukee Journal Sentinel, "I have received several calls. We are having ongoing conversations. There is a market for the best pitcher available on the (trade) market. I don't think there's any question about that.
"It's no secret the position we're in now. I've been asked if he will make his next start for us Sunday. All I can say is it's a possibility. I just don't know now."
The Brewers started taking offers for Greinke after a 0-6 trip to Cincinnati and Philadelphia dropped them out of contention in the NL Central. Another factor was the inability to convince Greinke to sign a contract extension before testing free agency.
