Nomar Garciaparra, Jason Johnson and Mark Sweeney all filed for free agency today, joining Manny Ramirez, Greg Maddux, Joe Beimel, Derek Lowe and Casey Blake from Thursday. That leaves Jeff Kent and Rafael Furcal and possibly Pablo Ozuna (option) as the only potential free agents yet to file. Forty-man roster is at 32, not counting 60-day DL guys.
