Richard Hernando Alonzo is a Filipino professional basketball player for the Rizal Golden Coolers of the Maharlika Pilipinas Basketball League (MPBL).
He was an undrafted player signed by the Purefoods Tender Juicy Giants in 2008 before being traded to Burger King.[1] Burger King traded Richard Alonzo to Barako Bull for Carlo Sharma.[2]
In 2015, Alonzo was signed by the Pacquiao Powervit Pilipinas Aguilas (later the Pilipinas MX3 Kings) of the ASEAN Basketball League (ABL) as one of the team's local players after being left unsigned by Kia. However, in December 2015, Alonzo, along with Emmerson Oreta, Charles Mammie, Sunday Salvacion, Jondan Salvador, and Andrian Celada were released by the Pilipinas MX3 Kings after a roster overhaul.
