His partnership with Yap produced several final four appearances, hundreds of three-point shots converted courtesy of Yap, hundreds of assists courtesy of Artadi, and millions of fans who became followers of perhaps the most celebrated back court tandem in the history of the Philippine's premier collegiate basketball league.

As backup point guard to Roger Yap, he managed to help Purefoods capture the championship in the 2006 PBA Philippine Cup.
