Team by team top prospects

1 Jarrod Parker , RHP , ARZ
Parker has some of the best stuff in the minors will be on hold until 2011 because of Tommy John surgery.
2 Brandon Allen , 1B , ARZ
Allen won't walk a lot and will K plenty, but should hit a ton in Arizona, especially against RHP.
3 Bobby Borchering , 3B , ARZ
Sweet swinging Borchering is a switch hitter has been compared to Chipper Jones.
4 Marc Krauss , OF , ARZ
Krauss swings a strong bat and has good strike zone judgement. He is a below average OF and will have to be a LF in the bigs. Could be a steal at 64th overall this year.
5 Daniel Schlereth , P , ARZ
Schlereth has great stuff and could be the closer of the future. Just needs to improve his control.
6 Matt Davidson , 1B , ARZ
Davison has big power and has been compared to former D-back Matt Williams. Will need time to develop and cut back on strikeouts.
7 Josh Collmenter , RHP , ARZ
Collmenter has a mediocre fastball, but mixes pitches well and knows how to pitch.
8 A.J. Pollock , OF , ARZ
Pollock is an athletic college player is good but not great across the board. I see his as Jason Pridie type.
9 Bryan Shaw , P , ARZ
Shaw is a power pitcher and gets a lot of ground balls. If his walk rate improves he could really break out.
10 Mike Belfiore , LHP , ARZ
Belfiore rojects to be a 3rd starter with a decent fastball, curve and change. Debuted in rookie ball, he needs polish.
