there's gossipy stuff about a former travel secretary. This person was an assistant Clubhouse Mgr (visiting), then got promoted. When Verlander dumped his HS sweetheart (after buying her a house), for Kate, she began dating this person, I think he even moved into the house. JV tried to get him fired. Doug Fister got involved about the unfairness of it all. Some suggest that's why Fister was traded so abrubtly. I know the guy's name but won't say it publicly.
It's gossip so take it with the appropriate grains of salt. This may have been something I read from a noted jerk on twitter that isn't around anymore. Or I might have gotten it from someone I know who's connected. (I got dope on Al Sabotka's issues with the Red Wings too).
