For the 18,173 hardy souls who braved scorching temperatures and allegedly made it to Oriole Park at Camden Yards on Sunday, the Baltimore Orioles-Boston Red Sox contest turned out to be a humdinger. The O’s won 5-1 with a one-hitter and solid offense including three home runs. The word, “allegedly,” applies because the ballpark looked much emptier than the official attendance estimate, an ocean of empty green spotted with the occasional baseball fan like floating jetsam in a sea of folded seats. Even under the circumstances (sauna-like temperatures, sink-hole-obstructed traffic, lingering suburbanite fear of crime, and, above all, the team’s woeful performance this season), it was a dreadful number. Only one team drew worse and that was Tampa Bay where fewer than 15,000 souls showed up to see their team beat the White Sox, 4-2, in a much cooler environment given that Tropicana Field has an air-conditioned-dome.
