#Pirates sign 20-year-old RHP Cesar Lopez as a non-drafted free agent. The Cuban born pitcher has been playing in Mexico.— Jenifer Langosch (@LangoschMLB) March 1, 2011
Ben Badler reported a few weeks ago that the Pirates made this signing in September, but had to wait for him to get his visa. I assume Langosch reporting it now means it's gone through. UPDATE by Charlie: Vlad did some digging on this last month. Lopez was apparently signed for $600,000, so this is a fairly major signing.
