The Tribe hired Pete Loizzo as an area scouting supervisor and both Dan Budreika and Ethan Purser as professional scouts.
Grant had served as the Indians' director of amateur scouting the past nine years, and he's been with the organization for the last 23 years. He will continue to oversee the Tribe's 22 amateur scouts as well as the club's activity leading up to the Draft.
Melendez, Cleveland's area scouting supervisor in Ohio, Indiana, Michigan and Kentucky for the last eight years, will now oversee the Indians' upper Midwest area scouting supervisors.
Krause, who had been a part-time scout with the Indians, will assume some of Melendez's responsibilities by covering Ohio, Indiana and Kentucky for the Tribe. Krause was formerly an intern for Baseball America, a Double-A video intern for the Rays and later a baseball operations intern for Tampa Bay in 2014.
Loizzo will cover North Dakota, South Dakota, Minnesota, Wisconsin, Illinois and Michigan. He had served as an operations manager and sales associate for Inside Edge Scouting Services. He previously worked with the Dodgers and his alma mater, St. Olaf College.
Budreika spent this past season as the Marlins' video coordinator. Purser most recently worked as an amateur scout for the Rays after spending time as a prospect intern for Baseball Prospectus and Perfect Game.
