The Brewers are receiving "a lot of calls" regarding the availability of John Axford, Francisco Rodriguez and Mike Gonzalez, according to Jon Heyman of CBS Sports (on Twitter). He adds that Yovani Gallardo is also drawing "some" interest.
Axford started the season as Milwaukee's closer but lost the job after he allowed nine runs in his first 3 1/3 innings. Over the past five weeks, however, he's fired 18 1/3 scoreless innings in a row, striking out 18 hitters and walking just seven in that time.
A look at the custom Fangraphs leaderboard of relief trade candidates compiled by MLBTR's Tim Dierkes shows that each of the three relievers ranks in the top 20 in xFIP. All three are striking out more than a batter per inning, though all three are pretty significant flyball pitchers as well.
As for Gallardo, Brewers GM Doug Melvin spoke about the right-hander earlier this week. While he feels that Gallardo is important to their chances of winning games in the future, he also acknowledged that contenders will likely make him offers that he has to consider. Tim also analyzed Gallardo's case as a trade candidate earlier this year.
Yesterday, ESPN's Jayson Stark noted that the Brewers will listen on any position player other than Carlos Gomez, Ryan Braun and Jean Segura. I'd imagine that Kyle Lohse will also draw some interest from other clubs.
