BEEN THERE: I paid a brief visit to what was then called "CocaCola Field" on the way to see the Toronto Blue Jays in July 2015. See photos below.
When I bought the second edition of Green Cathedrals (1992), I learned of the existence of a new minor league ballpark -- Pilot Field (as it was originally known) -- that was actually the pioneer of the "Neoclassical" baseball stadiums, of which Orioles Park in Camden Yards was the first in the majors. (In fact, the angles of the outfield fences are similar in those two stadiums.) Pilot Field was a marked improvement over the Buffalo Bisons' previous home at War Memorial Stadium, and clearly outclassed The Diamond, a minor league stadium built in Richmond, Virginia just a few years before. In fact, it was built in part as a means to get a major league expansion franchise awarded to Buffalo, but that city lost out to Miami and Denver in 1993. That really wasn't a practical idea, however, as there was only limited space in downtown Buffalo to expand the stadium. Nevertheless, a hypothetical expanded version of Sahlen Field with a third deck is shown above. Illustrating the tight space available, a major thoroughfare passes within a few feet of the left field fence, and a 60-foot high net was installed to prevent home run balls from crashing into automobiles. Beyond right field is a party deck with table seating, and a grassy slope for casual fans. Beyond those seating areas is a multi-deck parking garage, visible in the panoramic photo below. A nice defining feature of Sahlen Field (which is named for a regional sausage and meat packing firm) is the pyramid-shaped pavilion with a big sphere on the top, at each extreme end of the grandstand. Another aesthetic touch is that roof of the grandstand has cross-hatches that remind one of Bavarian architecture.
As one of the many strange consequences of the coronavirus pandemic, the Toronto Blue Jays were forced to find an alternative venue for playing their home games during the 2020 season. (The Canadian government refused to allow American baseball teams across the border to play at the Rogers Centre.) Sahlen Field made perfect sense, as it was geographically close to their real home in Toronto, and was the home of their minor league affiliate, the Buffalo Bisons. Since all minor league games were canceled in 2020, they were able to make all the necessary upgrades to the facilities, including stronger lights, repaired infield turf, and better dugout and clubhouse facilities. They also added huge promotional banners covering the empty seats (not shown in the diagram), as has been done in most other MLB stadiums. On August 11, the Blue Jays played their first "home away from home" game at Sahlen Field, winning 5-4 in ten innings -- taking advantage of the temporary extra innings rules. (See the Anomalous stadiums page.)
