The Milwaukee Brewers were taking calls from teams interested in acquiring Zack Greinke on Wednesday and now, losers of six straight games, have entered "sell mode" with their right-handed starting pitcher, Tom Haudricourt of the Journal Sentinel.

"It sounds like he's as good as gone," said that major-league source. "There's no reason for them to keep him now." The teams believed to be making the strongest push for Greinke were the Texas Rangers, Atlanta Braves and Los Angeles Angels.

Some of the top Brewers scouts have been watching the Rangers' top prospects, including pitchers Martin Perez and Justin Grimm.

Greinke, who is a free-agent at season's end, might be willing to sign an extension with the Braves or Angels. He holds those two organizations in high regard, according to Jon Paul Morosi of FOX Sports.

As I wrote today, Zack Greinke holds #Angels and #Braves organizations in high regard; might be willing to sign extensions there if traded.

The Brewers made attempts to keep Greinke in Milwaukee, offering him a five-year deal upwards of $100 million, but the record contract extension signed earlier this week by Cole Hamels made retaining Greinke an impossibility.
