Peterson captured three for 13 in that match on Saturday, which proved to be the turning point as the Tridents romped to a 17-run win and moved smartly to the summit of the CPL-table.
The 35-year old left-arm spinner removed Chris Lynn, Mahela Jayawardene and Jermaine Blackwood in the space of six deliveries to set up the victory.
Peterson is second from the summit on the list of bowling averages at the Caribbean T20-tournament, having taken 12 wickets in his first eight matches at an average of 14.58.
His exploits for the defending champions are no surprise. Peterson received the coveted prize for the domestic limited-over player of the year at Cricket South Africa’s award-ceremony in June after taking 18 wickets for the Cape Cobras in the Momentum One Day Cup tournament in 2014/2015.
Peterson also produced some sterling performances for South Africa in the T20-Internationals against Australia and in the One Day Internationals (ODI) against the Baggy Greens in November 2014.
He captured four for 32 against Australia in the fifth ODI.
The slow bowler also nipped out three for 28 in the series-defining third T20-match in Sydney against the team from Down Under.
Peterson has represented South Africa in 21 T20-matches, taking 24 wickets, and could force his way into the South African ICC Twenty20 World Cup squad if he continues his superb run in this format of the game.
Kieron Pollard, Peterson’s teammate for the Tridents and the star in the Cape Cobras’ Ram Slam T20 Challenge campaign, has smashed 279 runs in eight matches for the Tridents at an average of 46.50.
