SAN DIEGO – Whether they're in the field or at the plate, the Houston Astros are finding it tough to summon their usual postseason proficiency so far in the AL Championship Series.Almost as tough as José Altuve is finding it to throw to first base from shallow right field.Altuve's two throwing errors were the lowlight of Houston's 4-2 loss to the Tampa Bay Rays in Game 2 on Monday, with his first error prolonging the first inning and leading directly to Manuel Margot's decisive three-run homer.“We’re very surprised,” Astros manager Dusty Baker said. “That’s his first throwing error all year, and he hit two of them today."Altuve's mistakes and another quiet day at the plate have put the defending AL champion Astros in a 2-0 series hole in.
