In an ideal world, Jono Dean would have spent his Sunday nursing a hangover from his brother's wedding. And while he was ''shattered'' at missing the big day only to sit on the Adelaide Strikers' bench in the Hobart rain, the ACT Comets captain knew he couldn't pass up the biggest break of his career.

His other brother, Blake, also pulled out of sibling Sean's wedding on Saturday after a late call-up to debut in Sydney Thunder's loss to Sydney Sixers.

Hard-hitting batsman Jono was left out of the Strikers' final 11 for its washed-out clash with Hobart Hurricanes, while Blake managed just three runs and 1-29 off two nervous overs of leg spin.

Jono had mixed emotions when he was named in Adelaide's 13-man squad for its Big Bash opener, but said Sean understood it was an opportunity he couldn't ignore.

''I was pretty shattered I missed the wedding to be honest, it's not every day your brother gets married,'' Jono said.

''I'd known a few days beforehand I was going to miss it, but I think he understands what we're trying to achieve.

''Blake got called into the Thunder squad late and it was disappointing not to be there, but Sean was excited for us.

''It's too good an opportunity to pass up, you miss one opportunity and it could be your last.''

It is believed Thunder skipper Mike Hussey played a big role in Blake's selection after seeing him bowl for the Comets in a trial game.

Despite snaring the wicket of Sixers top scorer Nic Maddinson, his spell was littered with no-balls and wides.

Jono backed his brother to benefit from the experience. ''He's obviously shattered about losing the game and not performing to the standard he wants,'' he said.

''Speaking to the [Strikers] players, 90 per cent of them had a relatively ordinary debut,'' he said, hopeful he can do better if he gets to debut in the next few weeks.

''[Blake's] pretty disappointed but he'll bounce back, he'll be better for it.''

Wests-University of Canberra paceman Ben Oakley was chosen to make his Big Bash debut for the Strikers, but didn't bowl after rain ruined any chance of a result.

It stayed away long enough for Jono to see he faces a tough task to crack the Strikers' top order after openers Michael Klinger and Alex Hales smashed 87 runs in just six overs.

''It's a pretty tough squad to break into with two Australian players [Phil Hughes and Callum Ferguson] and one of the best T20 cricketers [Hales] going around,'' he said.
