With him, Alvin Patrimonio and fellow Alaska teammates Kenneth Duremdes, Bong Hawkins and Jojo Lastimosa, the Nationals took home the bronze medal in the Bangkok Asian Games.

With Rudy Hatfield and former Alaska teammates Lastimosa and Juinio around, they led Pop Cola to a third-place finish in the All-Filipino Cup.

In the 2005–2006 season, Abarrientos shared point guard duties with fellow FEU alumni, rookie Dennis Miranda and Dale Singson.

He played reserve role to lead point guard and 2009 Most Valuable Player Jayjay Helterbrand, as his court generalship gave additional factor in the Kings' line-up.

The Flying A made a memorable moment when he surpassed Ramon Fernandez as the all-time leader in steals on February 5, 2007, as Ginebra defeated the Talk 'N Text Phone Pals and won their semis matchup, 4–2.

Ginebra would go on to win the 2006-07 Philippine Cup against San Miguel, 4–2, with Abarrientos hitting a three-pointer in a crucial stretch of the final game.

But, during the KFC Philippine Cup 2009-10 of the PBA, when Celino Cruz, Jayjay Helterbrand and Mark Caguioa got injured, Head Coach Jong Uichico brought back Abarientos to the active roster as point guard.
