Astros general manager Jeff Luhnow worked as a ticket-taking usher at Minute Maid Park during Tuesday's game against the Cubs. Fans barely batted an eye as Luhnow scanned tickets and greeted fans with a friendly "enjoy the game." He fielded not a single question. Luhnow was recognized once, by a regular at Minute Maid Park who puts up the "K" signs in the outfield at just about every game.
