So the AD's have finally put into motion a postseason tournament for baseball (and maybe softball). After years and years of being against this, legislature is out and now needs to be voted on to be approved. Might go into affect in 2021.
So where should they host it? Most of the Pac12 sports that have tourny's do it in Vegas, and makes sense for baseball to be there also. Aviators (A's AAA affiliate) have a brand new stadium there which is nice. Seems like the best location. Once you start getting into other areas out west, it can make it hard to either get to, or gives one team a decided edge in fans/crowds and it becomes more a home series. Non die hard fans from Oregon/Washington are not traveling to Arizona, Southern California for a weekend (and vice versa) when they just can watch it on tv. Spending 4 days in Vegas though might have other incentives and reasons to make the trip. Not saying ideal or that "everyone wants to go to vegas" but tournament then becomes an attraction, rather than just a couple extra games on the schedule.
Phoenix area obviously has all the spring training facilities and is easy to get to, but again, with ASU being there and UA real easy drive, could become more a "home series". LA could host (as could SF), but again, local teams close by. I could see San Diego being an attraction and that would check some boxes also.
