Anybody know what is going on with this guy? He threw 2.2 innings on April 12th for his only start of the year, and hasn't made another appearance since. He is a very interesting prospect. 21 year old 6'8" lefty starter for the Florida Marlins who can hit mid 90's with his fastball. 

He had surgery last March and missed all of '07 with a torn labrum. I was hoping he would come back strong this year, but he has only made one start. I am worried that with this injury and his durability concerns, he may never be able to reach his potential. I hope this is not true, and any information would be greatly appreciated...thanks.
