How many games/innings should veteran players play in spring training vs how many innings for developing prospects.

I do not understand the point of Spring Training for players that have reached full ratings unless there is some type of penalty for not playing them.

Thanks in advance for your responses.

I set my spring training lineups to switch out the starters after three or four innings. Major leaguers start the first three games, then sit till the last two. Major league starters get one rotation the first five games, then one rotation the final five games. In between everything else is minor leaguers.

Major leaguers end up with about ten at-bats, pitchers two or three appearances (relievers).

It's been suggested that if you completely rest the major leaguers they'll experience a slight decline, but I haven't tested it.

Prospects. I don't play major leaguers unless they are old and at significant risk of decline, and then I play them 4 games. Never gotten a decline using this strategy.

I've for a long time now I've gone with 9GP (which is half ST sched.) and 20ABs for vets where I switch them all out for prospects at the 5th inning. Vet pitchers I do 3 appearances. I gotten fairly good results doing it this ways but I like hearing what other owners have done cause I'd like to cut down ST AB's to absolute min. to avoid injury. I rountinly don't play players ages 27-29 in ST cause they don't stand to gain or lose ratings so they don't need AB/innings at all.

Thanks for the insight.

What many owners don't realize is that for position players, fatigue starts in ST and carries over into the regular season. I understand why many severely limit MLer playing time in ST. However, MiLers who get 40+ plate appearances in ST are going to have fatigue issues later in the season, depending on durability rating of course.

So is it better to get prospects ABs in Spring training or limit them too so they don't get fatigued in season? How many ABs and innings should I give my top prospects in spring training games for them to improve ratings without the risk of fatigue ?

thanks in advance
