For those who are wondering, Armando Alejandro Estrada was from Ohio Valley Wrestling. He was known as Osama Rodriguez Alejandro (aka Big Lalo) in OVW.
WWE trademarked the Lalo nickname and his new ring name a few weeks ago. Estrada has been a big pet project for Paul Heyman over the past few months. A big part of his deal in OVW was a pairing with Robbie Dawber.
Umaga, his protégé, is better known as Jamal from Three Minute Warning, who was brought back several months ago.
