Glamorgan Dragons made light work of the 155 run target set for them by Gloucestershire Gladiators earlier in the day.
Although captain Alviro Petersen went for 20 with his side on just 29, some good batting from Allenby and Rees kept the scoreboard ticking over. Even when Allenby went for 30, with Rees still in and nearing his half century, Glamorgan always looked favourites at the Swalec Stadium.
Although Walters went for just four after Williamson had made a superb catch, diving forward and catching the ball just inches above the ground off the bowling of Dawson, Glamorgan continued their charge.
When Rees did eventually reach his half century, off 84 balls, his batting partner Wagg decided to get in on the act as well as he smashed the next ball for six, breaking the sight screen in the process with less than two weeks until the Swalec Stadium hosts England v Sri Lanka.
Although Wagg departed on 22 as he ballooned a shot in the air and was caught by O’Brien on his Gloucestershire debut, it could not stop Glamorgan reaching 155 as Rees swept four to make the scores level before running a single even though Wallace was caught just one ball earlier.
Glamorgan Dragons beat Gloucestershire Gladiators by five wickets in the CB40 at the Swalec Stadium.
