Keith and DVR discuss several second-half promotions, including Vaughn Grissom's callup to Atlanta -- plus the Braves' decision to extend Michael Harris II and Austin Riley this summer -- Brett Baty's opportunity with the Mets, and Shea Langeliers' debut with the A's. Plus, expectations for Nationals pitcher Cade Cavalli, and the expected late-season debuts of Corbin Carroll and Gunnar Henderson.
