Cummins took 1-40 from his four overs for the Perth Scorchers in Thursday night's five-run win over the Adelaide Strikers at the WACA Ground.
The 20-year-old bowled around 142km/h against the breeze on his return from stress fractures in his back, but has the potential to regularly reach 150km/h, the AAP reports.
Cummins, who made a stunning Test debut in 2011, is confident it won't take long for him to rediscover his rhythm and pace.
He said he is not holding back his pace on his return from injury and trying to rip in, adding that it may take one or two games to return to his regular pace.
Cummins said the main thing for him is to be accurate.
