Dylan Rockford predicted Arizona will move ace Zach Gallen before the trade deadline. Rockford thinks several contenders—he specifically listed Houston, Toronto, Seattle, the Cubs, the Phillies and the Padres—need a frontline starter and have the prospect capital to get a deal done. Because the Diamondbacks are fading and Gallen’s value is peaking, Rockford expects Arizona to cash in now. Bettors holding Diamondbacks futures or Cy Young tickets should be prepared for a potential odds shift once Gallen is moved to a new park and league.
