Liover Peguero, SS, ARI is also an interesting prospect whose name has come up. John Sickels answered a question about him in his recent prospect mailbag and he was mentioned in a FG article about being upgraded to a 45+FV, basically putting him in the tier just outside the top 100. He's 18 and his numbers have been very good this year:
.364/.410//970 in Rookie ball
.306/.358/.828 in Class A short season
FG says he's got a very good hit tool and speed, and he projects as an everyday shortstop. He wasn't projected to have a lot of power, but is actually showing some.
