Tuesday night, standing idly in the vicinity of the on-deck circle, Gio Gonzalez turned and started talking to his boss. Principal owner Mark Lerner leaned forward in his seat next to the Washington Nationals dugout, nodding, chatting with Gonzalez as pitches whistled to the plate a few feet away. It was only the third inning, and already Gonzalez's teammates had afforded him a rare luxury. He could relax. For almost two months, the Nationals' offense had stood more as an obstacle than a support for Gonzalez. In a 7-5 victory over the Arizona Diamondbacks, Gonzalez earned his first win since May 5 and Nationals hitters stopped treating him like he had once stolen their girlfriends. As Ryan Zimmerman rested his shoulder and Bryce Harper rehabbed in Potomac, the Nationals erupted for five runs in the third inning, three coming on Adam LaRoche's opposite-field home run off right-hander Trevor Cahill.
