According to Jerry Crasnick, Justin Verlander has been placed on revocable waivers by the Tigers. This is not too big of a deal. Most teams put players on waivers. However, this could be a way to sure up the Astros’ rotation.
Whether or not the Astros interest in Verlander was overblown, they could have been interested in trading for him. However, ten minutes before the deadline, Bob Nightengale reported that Verlander would not be traded on that day. He mentioned they could revisit things in the offseason.
To trade a player like Verlander, there would be quite a bit of red tape.
