The Milwaukee Brewers are having fun this week. On Thursday, they signed Lorenzo Cain and traded a prospect bundle for Christian Yelich to boost their chances of topping the Chicago Cubs in the National League Central. On Sunday, their owner suggested another splash -- this time in the form of a top free-agent starter -- could be in the works. The Brewers have been tied primarily to Yu Darvish in recent weeks. Yet if that pursuit fails and they're unable to find better through a trade, it makes sense that Milwaukee's front office might spring for Jake Arrieta, Lance Lynn, or Alex Cobb. The need is there, anyway. Manager Craig Counsell said Sunday that the only locks for the rotation are Chase Anderson, Zach Davies, and Jhoulys Chacin -- with a handful competing for the other spots. Club ace Jimmy Nelson isn't expected back until June.
