Bryce Harper's game-ending grand slam and sprint around the bases gave a jolt to the Philadelphia Phillies and could be the prelude to a fascinating National League playoff scramble. As thrilling as the win was for the Phillies , the 7-5 final Thursday night was a kick in the gut for the Chicago Cubs, since both teams are in a tenuous playoff position. It's mid-August and the only sure bet to make the postseason is the Los Angeles Dodgers, who continue to barrel through their schedule with an 82-44 record and 18 1/2-game lead over second-place San Francisco.
