Jayiya, who joined Chiefs on a three-year deal from Cape Town City this month, played in the 2-0 win over Township Rollers in the semi-finals of the pre-season competition in Orkney.
Amakhosi went on to win the one-day spectacle with a 1-0 defeat of Free State Stars at James Motlatsi Stadium on Saturday.
"It was great to get game-time,” Jayiya told his club's website. “Especially also after the good pre-season camp we had in Potchefstroom.”
Jayiya is determined to match the fans' expectations at Naturena after two seasons without silverware under coach Steve Komphela.
“I grew up in a Kaizer Chiefs supporting family. My father, my mother, my grandfather, my sister… Everybody supports the Glamour Boys. That’s why it’s so great that I have now joined the club of my dreams.
“I won’t let the supporters down. I know how they feel, because I myself have always been one. I want to help Kaizer Chiefs win trophies,” concluded the 27-year-old, who scored six goals in 24 outings in 2016/17.
The Glamour Boys next face Soweto rivals Orlando Pirates in the annual Carling Black Label Cup at FNB Stadium on July 29.
