Waw is among the 10 new faces that have crossed to the struggling side. Others are Waw’s former teammate Collins Neto, former Sofapaka’s Meshack Karani and Robert Ouma.
Sony have also acquired Ambrose Ayoyi, Kennedy Odhiambo, Maxwell Onyango, Michael Apudo, Robert Mudenyu and Salmon Otieno.
The inclusion of the 10 is expected to bolder Sony’s fight to avoid relegation in the second leg.
Sony Sugar are currently bottom of the table with only 14 points from 17 matches.
