Was it merely a coincidence that the day after the A’s unveiled their umpteenth new stadium plan for Oakland – this one at Howard Terminal in Jack London Square on the water front – a group seeking to bring major league baseball to Portland, Oregon announced it has signed an agreement in principle to develop a 45-acre site for a new state-of-the-art stadium on the Willamette River.

For the gift-giving Holiday season, here are three recommended books: (1) Jane Leavy’s “The Big Fella” (Harper-Collins) which proves conclusively there really was room for another book on Babe Ruth, only because of Leavy’s usual diligent and extensive research, (2) “Powerball” (Harper-Collins) by Rob Neyer, one of the very best baseball writers today who brilliantly dissects modern (post-2010) baseball of analytics, shifts, etc., through the lens of an ordinary, meaningless game between the Astros and A’s in 2017, and (3) “Baseball Cop” (Hachette) by Eddie Dominguez with Teri Thomson and Christian Red.
