Mamaril then applied for the 2003 PBA draft. Although he grew up in the US, since he was born in the Philippines and had a Filipino passport, he was eligible for the draft. He was selected sixth overall by the Purefoods TJ Hotdogs and signed to a three-year deal. As a rookie, he competed in the Slam Dunk Contest during the 2003 All-Star Weekend.

During the 2004 PBA draft, Mamaril was traded to the

With Shell taking a leave of absence from the league, Mamaril was traded to the Coca-Cola Tigers for Gec Chia and Edwin Bacani in 2005. With several teams looking to trade for him, Coca-Cola signed him to a two-and-a-half-year extension worth ₱7.5 million. With Coca-Cola, he made his first All-Star appearance playing for the North team.

Barangay Ginebra Kings

In 2006, Mamaril became part of one of the most controversial trades in PBA history which also involved Rafi Reavis,

as a free agent and Ronald Tubid via another trade strengthening the team even more, Ginebra made the 2006–07 Philippine Cup finals, making this Mamaril's first time to play in the PBA finals. Ginebra went on to win the finals. During a preseason game between Ginebra and the Magnolia Beverage Masters, Mamaril was punched repeatedly by Magnolia's Andy Seigle. Although both were pulled from the game, they were later able to finish the game and apologize to one another. Since Mamaril was only defending himself during the confrontation, he didn't have to pay a fine, while Seigle had to pay ₱10,000. In a loss to Welcoat during the 2007–08 Philippine Cup, Mamaril led the team in scoring with 17 points. In the following conference, they reached the 2008 Fiesta Conference finals. Facing the Red Bull Barako, Ginebra won the finals, and Mamaril got his second title with Ginebra.

Return to Barangay Ginebra

A month later, Mamaril was then returned to Ginebra for a future pick. After playing three games at the start of the 2011–12 Philippine Cup, Mamaril had to step away from the team for a while as he had to tend to his wife, who had just suffered a seizure.

In a loss to Alaska during the elimination round of the 2015–16 Philippine Cup, Mamaril scored 13 points. That conference, he helped GlobalPort make its first semifinals appearance after he sent their do-or-die match against Ginebra into overtime, in which his team was able to win. Facing Alaska once again in the semis, in Game 1, he contributed 12 points, seven rebounds, four assists, three steals, and a block while his teammate Terrence Romeo scored 41 points to get an upset win over the more experienced Alaska.
