The soundtrack to Astros pitcher Wandy Rodriguez's season is taking shape thematically, if not so pleasingly. Cue up U2's "Get On Your Boots" for the opening credits. Drop in Nancy Sinatra's rendition of "These Boots Are Made For Walking." Add, for the country music constituency, Shania Twain's "Whose Bed Have Your Boots Been Under." Boots and blunders littered the landscape again in Rodriguez's second outing of the season for the Astros, a 6-3 loss to the Atlanta Braves on Wednesday night. A crowd of 18,225 showed up to Minute Maid Park, in Astros parlance, to Root. Root. Root. The Astros took it as another occasion to boot, boot, boot, boot, committing four errors and an assortment of other miscues over three hours and 21 minutes of game time.
