This is a subject that comes up a couple of times every year; the possiblity of the WinPicks database wizards coming up with a module for NHL and/or MLB.
The first few years I used WinPicks, I tried to encourage them to develop a MLB program as I would share suggestions. As I was told, the fact is they simply have no plans in that direction.
So, I've arrived at the place where I just accept the reality that I have to make do with the limitations of the finest basketball / football handicapping software available anywhere in the solar system.
They may not do hockey and baseball, but they're the absolute best at basketball and football.
