When the Cincinnati Reds decided to keep Phil Ervin and Tyler Mahle on their major league roster to start the season, they took two of their top thirty prospects out of the minors. The Reds kept Mahle up out of necessity, even though he had a strong spring. Ervin, meanwhile, had overcome all of his weaknesses in the minors, save inconsistent power and would be platooning if Hamilton wasn’t around.
Louisville had infielders Nick Senzel and Alex Blandino until the injury to third baseman Eugenio Suarez. Now, Blandino is with the big league club.
