"And last but not least, I’d be remiss if I didn’t single out one team that warms the cockles of my heart: the Baltimore baseball Orioles of Maryland, who broke the record for most homers allowed in a season in game number 128, and also whom we haven’t picked on enough lately. They wound up allowing 305, with the gap separating them from everyone else large enough to drive a semi-truck through."
. . .
"My favorite part of their season, though, might be their stretch from July 29-Aug. 10. In that time, they played 11 games, and they allowed 5+ homers in six of them. Go take another look at that chart. Only eight other teams (Reds, Tigers, Astros, Rockies, Cubs, Rangers, Pirates, Angels) have ever had six such games in a season. Which means 70 percent of MLB teams have never had an entire season with six such games. Again, the 2019 Orioles did so in an 11-game stretch."
