According to Baseball America, the Astros have signed Dominican LHP Junior Garcia for a $200,000 signing bonus. This is in addition to two other Dominican Republic signings announced by the DPL Baseball website earlier this week.
According to the DPL Baseball site, the Astros signed Joselo Pinales, a 6'1" 180 lb. right-handed pitcher from La Romana in the Dominican Republic (h/t to Brian Stevenson for catching this one) as well as Catcher Oliver Toribio this week as well.
When I talked to Jeff Luhnow late last month, he indicated that he would be headed to the Dominican Republic after the winter meetings to look at a few prospects. It appears that is precisely what he's been doing this week.
The Off-Season Transaction List has been updated with these signings.
