Andy Dinh (born April 19, 1992), better known as Reginald, is an American entrepreneur and former professional League of Legends player.

Going into League of Legends Season 2, TSM suffered losses while facing the Russian-based team Moscow 5 at Intel Extreme Masters Hanover and Kyiv events.

Following these defeats, notable founding member Christian "The Rain Man" Kahmann resigned from the team citing differences in interests and TSM subsequently picked up Marcus "Dyrus" Hill to fill the empty spot, as he was already living in the TSM house.

He made a brief appearance as TSM's mid laner in Week 7 of the 2014 NA LCS Spring Split due to Bjergsen returning to Denmark to renew his United States visa.
