Here's a scouting report from SaberScouting on Ismael Guillon, the LHP BA says the Reds are in on:
13. Ismael Guillon, LHP, Venezuela
Guillon is a big 6′3 lefthander that hasn’t been seen a whole lot, but has a good amount of polish for a 16 year old. He has a larger, more filled-out frame compared to fellow 6′3 Venezuelan hurler Portillo, and throws from the left side, but has a lower upside. Guillon works in the high 80s with his fastball and lacks bigtime projection, but has 3 workable pitches and some feel for pitching. He figures to get a bonus of about $700,000 as well.

Baseball America has a small profile on him from back in July. They say he's also a first baseman. Scouts say he has great power but he swings and misses a lot. On the mound they say he's got a 90-91 mph fastball but has a bad and funky delivery.
