The Brewers plan to make another attempt at extending Zack Greinke this year, but if talks don't progress they may have to consider trade offers for the former Cy Young Award winner. Greinke, who's on track to hit free agency after the season, would be one of the best pitchers available if the Brewers decide to sell. Here are the latest rumors surrounding Greinke with the most recent rumors up top:

The Brewers have a special assignment scout watching the Rangers’ Double-A affiliate, Jon Paul Morosi of FOX Sports tweets. The scout is not there on routine coverage, which raises the possibility that the Brewers are taking stock of the Rangers’ system in anticipation of possible trades.

The Braves are believed to be seriously considering a trade for Greinke even if they don’t have assurances of keeping him beyond 2012, David O’Brien of the Atlanta Journal-Constitution tweets. O’Brien doubts the Braves would offer Greinke $20MM per season on an extension.

A former teammate of Greinke’s told Jon Heyman of CBSSports.com that the right-hander would like to play for the Braves. Greinke likes Atlanta and wants to win badly, according to Greinke’s friend. The Braves, who have lost four of their past five games, haven’t yet decided how aggressively to pursue upgrades in midseason trades.

The Braves are willing to trade young arms for Greinke, Ken Rosenthal of FOX Sports reported yesterday.
