Gill had been unlucky to have a couple of dropped catches off his bowling, while taking a catch himself and being involved in the run out to get rid of Otago's well set openers, but having got their team through to the 26th over, it freed up the rest of the team to attack freely.
On Thursday against Wellington, Central Districts put up a defendable 250 on the Bert Sutcliffe Oval, although Gill and O'Leary were both dismissed for one run.
Wellington worked their way to the total, reaching it at the start of the final over from Gill.
He took 1-42 from 9.1 overs, while O'Leary finished with 1-28 from seven.
