BOSTON — The Houston Astros, the only defending World Series champions that we have, are extraordinarily good at winning baseball games. They are good at winning close games. They are good at winning blowout games. They are good at winning regular season games and they are good at winning postseason games. They are good at winning games in the spring, in the summer and especially in the fall. They are even good at winning extraordinarily awful, scabrous, gangrenous, leprous, odiferous, calamitous games like the first game of this year’s American League Championship Series, which they and the Boston Red Sox inflicted on the sport Saturday night.
