Further increasing his trade value, Gray is under team control for two more years, so he's far from a half-season rental.
At 53-48, the Brewers are leading the National League Central, but a half-game lead on the Cubs doesn't provide Milwaukee with much safety. As such, it makes sense the team is attempting to strengthen a starting rotation that ranks seventh in team ERA (4.08).
The Detroit Free Press' Anthony Fenech reported Thursday the Brewers also had Detroit Tigers starter Justin Verlander on their radar. While Verlander has a stronger body of work than Gray, he's also 34 years old and set to earn $56 million over the next two years.
While those two factors make Gray a better option for Milwaukee, the team's front office may need to shift gears should its hopes of working out a deal with Oakland begin dwindling.
