Re: Farm System question.
It means he is still playing and progressing ok... The real key, with his age, is to see where he is assigned this year. Alot of guys get picked up out of the independent league to just fill holes on minor league teams though... If he gets held back at extended spring training then you can count him as good as done.
Re: Farm System question.
I may not be an expert but there are several levels.
Basically it goes Rookie League, Short Season, Low-A, Hi-A, AA, AAA, MLB
Rookie League goes from June to Sept. I believe it is geared towards new draft picks but there are guys drafted from the previous year as well. I think there are mostly guys drafted straight from High School in this league
Short-Season is a step higher than Rookie League, but runs on a similar schedule (June to Sept). I think a majority of guys drafted from College start here, although I would expect decent high school guys to start at this level as well.
Low A - Full season (April to Sept), and it's the next level for guys to go. I would guess some stud draft picks may start at this level, but I think a lot of guys move up from the Rookie or Short Season Leagues
High A - Better level of play than Low A. Guys from Low A will get promoted to this level, yet again I am sure there are cases of stud draft picks starting at this level
AA - Higher level than A. You have a lot of cases of really good prospects going straight from AA to the pros. Personally this is one of my favorite levels of minor leagues as you can often see some future stars.
AAA - Just 1 level below the MLB. You will find a lot more career minor leaguers at this level or guys that are 1 injury away from going to the MLB. You also tend to have MLB rehab-start guys go down to this level while they get back in MLB form. I find AAA to suck. You see a lot of career minor leaguers and guys over the hill. If someone is really good in AAA, they will find themselves on a MLB 25 man roster somewhere. So if you go to I-Cubs games and see the same guys on a year in and year out basis, those guys aren't likely going anywhere.
So how does it all work? Well, depending on a guy's ability, they start at a level the organization deems fit. A lot of the lower leagues are getting guys adjusted to pro ball and getting used to wood bats. They then can move up between the levels as the organization sees fit. If a guy is outplaying competition at a certain level, they will move him up. They also will move a guy down if he seems to be a little over their head.
As far as your friend goes, I have NO idea. I will say that a vast majority of guys that get drafted never play in the MLB, but in the minor leagues.
Perhaps Cysbsball can chime in with some better answers for you, but that's what I know (or at least I think I know).
Re: Farm System question.
Being 21 and starting in Arizona means they didn't really have high hopes for him, normally the high school kids go to Arizona and Fl and the rest go to more advanced short seasons... The call up can mean anything, they could have just needed a filler because of other call ups or injuries, who knows... He did well, so that will help... This will be the big year for him at his age.
Re: Farm System question.
awesome guys, I really appreciate the insight.
