Baseball can sometimes turn on the edge of a knife, and this is certainly one way to explain this heartbreaker of a loss on Sunday. A few plays go the other way, and this result is different. As it was, with the O’s clinging to a 2-1 lead in the bottom of the ninth, Yennier Cano allowed three consecutive baserunners — and on a double-play ball that would have ended the game, shortstop Gunnar Henderson threw the ball wide of Ryan Mountcastle at first, allowing the tying and winning runs to come home. It was especially fluky because the Orioles defense had been brilliant all game.
