Trainers and injuries
 

How important are trainers to injuries?

I got devastated at the end of last season with both of my one two punch 5 star power hitters hurt and my number two pitcher on the DL, all for more than for 3 months are more. Two more injuries in the outfield had me limping through the season with 23 players ( I was already playing 1 star players and I didn't want to give anyone else a major leagur contract).

Will I see less time on the DL and hopefully less injuries if I spend more for training and a trainer?

Yes, that is their contribution to the game:

Trainer Ratings

Personnel are rated on five different trainer skills, as follows:

Rating/Description

Heal Arms, Legs, Back, Other - The ability to heal injuries to the specified body part. A higher rating means players with those injuries will heal more quickly, possibly more quickly than the original estimate. A higher rating also means players are less likely to get those injuries in the first place. See Injuries & Fatigue for more information about injuries in OOTP.

Fatigue Recovery - The ability to help players recover from fatigue. You can think of this rating as if your team also has a training staff. The better your training staff, the more 'in shape' your players will be, and therefore the more quickly they will recover from fatigue. See Injuries & Fatigue for more information about fatigue in OOTP.
