Pirates blank Cubs, stop 6-game winning streak

A.J. Burnett threw seven scoreless innings as Pittsburgh blanked Chicago.
The Cubs came in having won six in a row but were stopped in their tracks by Burnett (3-1), who allowed three hits while striking out seven in his seven innings of work to earn his third consecutive victory.
Burnett worked out of a bases-loaded jam in the fourth as he struck out Jorge Soler and escaped without damage when Starling Marte hauled in Chris Coghlan’s fly at the wall in left.
