A weekly look back at the best of David O'Brien's Braves blog on ajc.com: SAN DIEGO --- Maybe it's David Ross singing lines from EddieMoney's "Shakin'" at random moments before and after the past fewgames, including while he was dressing after last Saturday's win atSan Francisco, and as he walked down a hallway to the clubhouseSunday morning before the series finale against the Giants. More likely, though, the Braves are on a little roll nowbecause they were due for it to happen, because no one who followsbaseball closely believed the poor team hitting by the Braves in the first three weeks ofthe season was an accurate indicator of what was to expect over thecourse of the season.
