Abreu is a streaky guy. He and Contreras should still hit 20 HR. Hard to say about the rest of the team. Anthony showed some power last season, but has that crazy GB%. Mayer has natural loft, but is struggling with MLB pitching. Duran can get really hot and reach 20 HR. Rafaela hit 12 HR in a 40 game span last season.
I think the team has put themselves in a huge hole (winning %), but the overall offensive numbers should bounce back.
