Michael Santos: RHP, Dom. Rep. (6'4", ??) (DOB=??)
Santos has never shown up on any of my previoius prospect radar screens and I can't find any mention of him anywhere on the net beyond the description of him from the Dom. Prospect League website (see link below) where they give a recap of the recently-completed 6 team tournament that Santos's team won. Santos was named the outstanding pitcher of the tournament and threw 4 shutout innings, allowing 1 hit and striking out 4. BTW, the Giants also signed the outstanding pitcher of last year's tournament (Simon Mercedes for $400K), but Mercedes ended up being held out from making his pro debut in 2011 due to some old shenanigans concerning his use of a fake identity - so let's hope that Santos doesn't end up repeating the same pattern.
I don't know Santos's age or birthdate, so right now we can only say for sure that he turned 16 years old on or before August 31, 2011. If I had to guess, I would say that Santos recently turned 18 years old, give or take 6 months. I also don't have his physical measurements, but the DPL website does have a photo of him posted. From the photo, you can see that Santos is very tall and extremely skinny (not unlike Kendry Flores). I'm going to guess that he's at least 6'4", because in the photo he's standing next to Yairo Munoz (who I know for a fact is 6 feet tall) and appears to me to be at least 4 inches taller than Yairo.
Here's the link to the DPL story on the tournament and the Santos signing:
