thoughts on Madison Bumgarner, SP, Giants

[Shelton Southpaw]

I have read some great things about San Francisco's SP prospect, Madison Bumgarner, who is only 18 years old, & is currently in A ball.
Hear he has a good fastball, but his curve / breaking ball is in question, but could improve over time.
He looks good so far in A ball, with a strikeout to Walk Ratio of 116K:18BB

Basic Statistics
Year Age Team G W L IP TBF H 2B 3B HR R ER BB K ERA RA9
2008 A Augusta 19 10 3 109.1 431 90 16 1 3 27 21 18 116 1.73 2.22

My question to you all is he looks great in A ball, but how do you think he will perform in AA or AAA?
Do you think he can keep up similar numbers in the higher minor leagues?

Do you think he is capable of being an ace starting pitcher or a middle of the rotation SP at the Major League level?

HE is still available in my fantasy baseball league, consisting of 10 teams, and each team is allowed 3 Minor league baseball prospects.
Do you think & believe he is good enough to add to my minor league prospect list?
Would you have him ranked in the top 50-100 top minor league prospects overall?

Please tell me your thoughts about him on all of these questions.

I currently have Jason Heyward, Dexter Fowler, & Jeremy Hellickson on my minor league roster for prospects.

Thank you

He is a top 20 prospect that projects at the top of the rotation, but at 18 he has a ways to go.
