Roy played every game for the Invincibles last summer but failed to make an impact, with more ducks (three) than half-centuries (one) and was released by their coach Tom Moody last month. He entered the draft with a reserve price of 100,000, but the eight men's teams prioritised overseas players in the early rounds.

Each team will add a further two players to both their men's and women's squads ahead of the start of the season in July, who will be offered 'wildcard' contracts based on their performances in domestic T20 cricket. These will be worth 30,000 in the men's competition and 8,000 in the women's.
