3-0 and finally to Puerto Rico once again, this time 3–2 to win the gold medal and a berth for the 2017 FIVB World Grand Prix. Castillo was awarded Best Digger, Receiver and Libero. Nonetheless, she expressed that she does not play for the awards, that they come for the strength invested for playing for her native country, and that playing at home brings an extra motivation. Castillo signed with the Brazilian club Genter Vôlei Bauru for the 2016/2017 season. 2017 Genter Vôlei Bauru reached for the first time a Brazilian Superliga quarterfinals berth, but they were defeated by Minas 0–2 in the best-of-three playoff. After losing the first match 0–3, Castillo tattooed the John 3:16 Bible verse in one of her arms saying that these passage guided her life.
