MIKE Cortez formally joined the Blackwater coaching staff in the PBA On Tour on Sunday.
The former No. 1 overall pick was seen in the Bossing bench with fellow deputies Aris Dimaunahan and interim Jo Silva, who continues to call the shots for the team in lieu of head coach Jeff Cariaso.

Cariaso himself was already at the FilOil EcoOil Centre in San Juan to watch the team in action against the San Miguel Beermen.
Cariaso just arrived from the US after attending a series of coaching clinics.
