First-year Astros manager Bo Porter’s been on a media roll the last few days and he’s been a quote machine since spring training workouts began nearly a month ago. Tuesday, Porter was in top form. Asked by a reporter how he explains the Astros’ organizational overhaul — also known in sports as rebuilding — to his players, Porter got a little intense. Porter: What’s that word? What’s that word you just said? Reporter: Rebuilding. Porter: I didn’t even know that word was in the dictionary. I haven’t used that word, not one time, since Sept. 27 last year. And I’m not planning on using it.
