Third baseman Nick Castellanos is the consensus No. 1 prospect in the Tigers organization, and he gets high marks from Keith Law of ESPN.

But Law doesn’t think much of the Tigers’ other top prospects.

On Wednesday he revealed a top-10 list of prospects for every American League team. Castellanos, ranked No. 32 overall by Law, was followed on the Tiger list by outfielder Daniel Fields and left-hander Robbie Ray, acquired in the Doug Fister deal.

“Nick Castellanos is going to be a very good big leaguer, but after him, there's at least an argument that they don't have a future average prospect in the system -- a pessimistic argument, to be sure, but not a wildly unreasonable one,” Law says. “The Tigers have used their system aggressively to bolster the big league club, mostly via trades, and have lost some first-round picks to sign free agents, making it harder for the amateur scouting staff to keep pace.”

Here are the top 10 prospects in the Tigers organization, according to Law:

1. Nick Castellanos, 3B

2. Daniel Fields, OF

3. Robbie Ray, LHP

4. Jonathan Crawford, RHP

5. Jake Thompson, RHP

6. James McCann, C

7. Tyler Collins, OF

8. Corey Knebel, RHP

9. Endrys Briceno, RHP

10. Eugenio Suarez, SS
