The Rocks won the toss and elected to bat first at the Golf Club and another one-handed Ethan Dowling screamer removed Jye Woodger early at 1/5.
Matt Ryan (19 off 21) and Liam Hackenberg (13 off 17) were the only Rocks players to reach double figures as tight bowling worked wonders for Rovers.
Jackson Korn ripped through the middle to lower order to finish with figures of 4/9 off his four overs as the Rocks ended their 20 overs on 9/89.

Ethan Dowling then received a promotion to the top of the order and went nothing short of berserk.
Before the fourth over, Dowling was sitting on 7 off 9 but by the time that was over he was 20 off 13.
From there the Rocks were continually collecting the ball off the fairway with his innings of 61 off 28 balls including six 4's and five 6's with one over going for 28 runs.
Patrick Brennan (28* off 28) was a great foil at the other end as Rovers reached the target in 9.1 overs at 0/90.
