Al Avila put on his realtor hat on Tuesday afternoon. The Detroit Tigers general manager was talking about houses. A nice house, presumably. Maybe a colonial. “Let’s say you have an asset,” Avila said. “Your house. And somebody likes it. You don’t have it for sale. But if somebody says, ‘Man, I really like your house’ and they keep on pursuing you about your house, at some point, you might end up selling it.” In Avila’s analogy, right-handed pitcher Michael Fulmer is the house. And though the Tigers haven’t put Fulmer on the trade market, teams have passed by during the first two days at the Major League Baseball Winter Meetings and thought, “We’d really like to buy that house.” A day after Avila said the Tigers would listen to offers on their young ace, a couple of suitors emerged. And at least one figures to have the prospects to acquire Fulmer. The Yankees have checked in on Fulmer, according to Bob Nightengale of USA Today. So, too, have the Rangers, according to Evan Grant of the Dallas Morning News. “With Fulmer, we’re not actively pursuing a trade,” Avila said. “A couple teams have expressed interest and all we’re doing is listening and that’s really it at this point. I would say that, for us, it pays to listen and see what’s out there.”
