Sydney Thunder are favoured at 59%, and the case is built on a paper edge of about 5 runs. Their XI rates 7 runs better than an average side with the bat and 0.1 with the ball, against Melbourne Renegades' 4.5 batting and -2 bowling. The batting gap is 2.4 runs and the bowling gap 2.1, so the edge comes from both departments rather than one. Projected totals point the same way: Thunder 175 batting first, Renegades 167, around a par of 174.
Renegades' bowling is the weak unit, rated 2 runs worse than average, and Will Sutherland carries much of that: 7 wickets at an economy of 9.15 in his last 10 T20 matches, and a bowling rating 2 runs worse than an average bowler over four overs. Against a Thunder top order with David Warner at 3.8 runs better than an average batter, that is where the game tilts.
