Masterson doesn't get talked about enough here. Was ranked the 24th best player in the 06 draft by BA and was picked by the Sox in the 2nd round. Assigned to Lowell and dominated as a MR: 31.2 IP, 20 hits, 33/2 K/BB (16.5!), .85 ERA. Converted to a SP this year where he started off slowly, but hes coming around. Pitching in Lancaster doesn't help a guy but hes learning how to be a good pitcher there.
June: 30 IP, 27 hits, 16/2 K/BB (8.00), 3.26 ERA with a dramatically improved ground-out ratio.
Keep an eye out for Masterson, he's probaly the 3rd best SP prospect in the farm system.
