Daniel Nava said he's undergone a slight mechanical adjustment with the help of Triple-A Pawtucket hitting coach Dave Joppie.

Nava batted just .168 with two homers and three RBI in 95 at-bats before his demotion, so a drastic chance will be needed if he wants to make a splash with the Red Sox later in the season. Even if promoted at a later date it is hard to believe he will receive enough at-bats to warrant fantasy consideration. ANALYST: Matthew Beck Mobile App
