The Milwaukee Brewers improved their lineup, and they are now working hard on their rotation – hard enough that they seem determined to land at least one of the “big four” starters on the free-agent market. It will be a surprise if they do not. And here’s an interesting question: Is it possible they could go for more than one top starting pitcher? They have been contact with the other top starters in addition to the well-chronicled pursuit of Yu Darvish, and the Brewers only have three set starters in the rotation at present – Zach Davies, Chase Anderson and Jhoulys Chacin. The Brewers were reported by FanRag Sports to be strongly in the mix for Darvish, who is said by sources to have at least one five-year offer and at least one (and probably multiple) offers for at least $100 million – though he has been seeking something closer to the Stephen Strasburg deal of $175 million for seven. The Brewers, who haven’t signed an outside free agent for $100 million or more in their history (they made nine-figure offers to their own Prince Fielder and Zack Greinke, and locked up Ryan Braun with such a deal), are thought by some to have been the most aggressive to this point in the Darvish derby, with the rival Cubs (who are also believed to remain in the mix), Twins, Phillies, Rangers, Yankees and Dodgers also showing interest.
