The Bhoys heavily rotated on the back of their Champions League victory against Astana in midweek, bringing in six new players for the trip to Rugby Park.
Speaking to reporters after the match, Rodgers said: "Technically the players played at a really high level. We had good control of the tempo. I was so pleased with the contribution of some of the younger players.
"Tony and Calvin have been training with us since last season, they were exceptional today, showing nerve, calmness. It's a great sign for the future for the club that they can come in and play with quality, but they need good senior players around them as well."
