Not really critical mass when but more importantly when we will be at optimum strength for the play offs. Let's review the DL list and their expected returns and effectiveness.
Scherzer tonight and should be good to go by monitoring him daily for the neck discomfort
Werth this week with limited action until mid September
Turner Doesn't make sense to bring him back until minor league season is over especially with Difo being more than adequete.
Harper I don't see him getting back until the play offs and his effectiveness will be severely hampered by lack of re-hab starts
Madson No timetable set for him and hopefully mid -Sept
Romero Not much time for him to be throwing in actual games and his wildness has always been a consideration
Glover , Eaton , not this season
Raburn, Drew , Goodwin they are among the missing and we need them only to eliminate the need for Stevenson, De Aza , Sanchez
Please feel free to add someone I may have missed and your projection
