According to ESPN's Jeremy Mills (you are probably more familiar with Jeremy's NCAA-Baseball.com site), Michigan might the get chance to host a regional. I find this a bit surprising in light of the Wolverines start, but Michigan does have several factors working in their favor.
First, the NCAA has looked for a northern host the last few years. Michigan is probably the only northern program deserving of that honor. Second, you have to have the facility to host a regional. Freshly renovated Ray Fisher Stadium fits that qualification, as well. Third, is ability to draw a crowd. Michigan has drawn fairly well this year. And, while several western programs merit hosting a regional, the honest-to-goodness truth is many of them don't draw particularly well.
If Mr. Mills' prediction were to come true, I think having San Diego and Notre Dame in Ann Arbor would indeed fill the seats. Now, would the Maize and Blue faithful hang around if the home side got bounced? That's another story altogether. But it would be the same story at any site where the host was eliminated.
The final factor working in Michigan's favor to host a regional is that they've been playing very good baseball for weeks. They would need to maintain that pace (basically, taking a minimum of three of four games each of the final two weekends) and might need to hold off Notre Dame in their annual late-May midweek meeting near Grand Rapids to stay in contention for playing host.
Jeremy Mills knows more about college baseball than I ever will, so if he says Ann Arbor's in the running I'm apt to believe. Yet, I'm just skeptical. I just don't see the committee taking a northern program with an RPI in the 30's a chance to host over all those other southern/western programs. Of course, I'm often wrong, too. Regardless, I'd love to see a regional that close to home.
Now, for those looking for a contrary point of view, or digging around for other regional predictions, Mark Etheridge at SEBaseball.com offers up his field of 64. He's got Michigan at Georgia. (Yikes!)
