It wasn’t exactly a coming-out party for the Pirates, already strutting on Major League Baseball’s Main Street prior to Tuesday night’s 4-2 Interleague triumph over Detroit. With the victory in front of 34,919 in PNC Park, the Bucs did return to their season peak of nine games above .500 while gaining a game on each of the three other National League Central contenders, nearing within 1 1/2 games of the leading Brewers.
