The match was a personal triumph for Proteas' all-rounder Robin Peterson who took 3/24 as the Diamond Eagles crumbled to 101 all out in 19 overs after winning the toss and then scored 49 in an unbroken century partnership with Justin Kreusch to see his side to victory.
The Warriors and the Eagles will play a third leg at Sahara Oval St. George's on Wednesday evening while the Nashua Dolphins and the Nashua Cape Cobras will also go to a third leg at Sahara Stadium Kingsmead on Wednesday.
At stake is a place in the final as well as the two qualifying places in the Champions League to be played towards the end of the year.
