Kerr won the award for the month of June after guiding his side to five league victories that left K’Ogalo perched at the summit of the table with 12 points clear.
This is the second time that the Briton has won the award having lifted it for the first time in September 2017. Kerr guided Gor Mahia to a 4-0 victory over Wazito in Kisumu then followed it up with a 3-1 thumping against Nzoia Sugar.
Kerr became the fifth coach to have won the gong this season, after Francis Kimanzi (February), Dennis Kitambi (March), Sammy Okoth (April) and Anthony Mwang (May).
The award comes with a personalized trophy and a cash prize of Sh75, 000.
