Ari in Philadelphia and Gerry in Piscataway join Dave once again to look at the MLB Trade Deadline.  Who should buy and who should sell?   Did the Diamondbacks land a game-changer with J.D. Martinez?   Will Jaime Garcia be the piece the Twins need to make the playoffs?  Are the Royals over confident in trading for Trevor Cahill?   What's to come for contending teams like the Dodgers and Astros?   Did the Nationals finally get the bullpen help they needed by trading for Madson and Dolittle?  That and much more as we go into the second half of the baseball season.
