Sickels posted a review of the top 50 pitching prospects in 2005. Here are the Rangers:
36) Thomas Diamond, RHP, Rangers: Working his way back from arm problems. Still has a slight chance.
39) John Danks, LHP, Rangers: 31-33, 4.06 ERA, 114 ERA+ in 534 innings. Bad rookie season but has been very strong since.
43) Juan Dominguez, RHP, Rangers: 5-10, 4.60 ERA, 104 ERA+ in 110 innings. Remember this guy? He looked really good for a bit, but got hurt.
I hope the blockquotes work. Is "got hurt" a euphemism for "lacked a brain".
