Unwanted Def Replacements

My whole team got replaced by backups in a close game for "defensive replacements" and not only did I not want my starters out, many of the replacements have worse def stats. I have these guys on my roster in case of injuries, should I drop them or is there something else I can do?
Thanks

Do you have your "Rem. 4 def sub" boxes checked? It's under Hitter Preferences. You want them unchecked.

That was it......thanks, weird thing is I don't remember checking them .
Thanks

No problem!

INJURIES
Can anyone explain why Strat is violating it's own rules, and allowing "1" rated players to get hurt for 60 games? It's completely out of control in my league, where one team just finally got back a "1" rated pitcher from a 60-game injury only to have him get hurt for another 60. Similarly, I got one of my position players back from a 60 game injury, and in the next game, had another go out for 60. It's ridiculous.
