Yes it’s because he keeps changing the lineup everyday and resting his best players too much. They aren’t scoring enough runs because the bottom half of the lineups are terrible. He also needs to stop playing Leury and Harrison the same game. They are more like utility or bench type players in case a starter goes down or if they don’t have any other option at a specific position because of injuries. Just play one of Harrison or Garcia at 2b everyday and keep the other on the bench in case they need a pinch hitter late in the game or a sub and that’s it. It weakens the lineup when they have both out there at the same time. For the outfield, they should just keep Pollock in LF until Eloy comes back, Robert in CF and Engel in RF. Sheets and Vaughn aren’t outfielders. Just rotate Vaughn and Abreu at 1B/DH with Sheets as the DH sporadically to relieve both of them but don’t play Sheets at 1B. Don’t play Grandal at DH or 1B either. Just rotate him at C with McGuire.
