Who is next for Katie Taylor? A look at the world number one and the four other belt holders
So it's eight out of eight and a potential homecoming in Dublin for the indomitable Katie Taylor.
The Bray pugilist has, as expected, shot to the higher echelons of women's professional boxing in a short space of time and following last night's successful defence of her lightweight title after 10 tough rounds against America's Jessica McCaskill, she proclaimed she is chasing all five belts.
McCaskill was never going to be the 16-1 pushover her pre-fight odds suggested. Although relatively inexperienced, the Chicago woman was only beaten once in her previous six outings in the pro ranks - a split decision against Katonya Fisher in her second fight in June, 2016.
Her other five encounters ended in comfortable victories - three by knockout and two by unanimous desicion.
So where now for Katie and who stands in her way of achieving her dream?
Taylor has shot up to number two in the world rankings and holds the WBA belt. The ultimate goal is surely world number one Delfine Persoon from Belgium, a daunting prospect with just one defeat in 40 fights and that coming all the way back in 2010.
Persoon holds the WBC belt but is not on Taylor's radar right now.

Instead, the Irish women's next bout looks likely to be against IBF champion Victoira Bustos from Argentina in Dublin early next year after Eddie Hearn confirmed talks have already began.
One curious fact about Bustos' career is that the 18 fights she has won have all gone the distance. The probable date of that showdown is in April in the 3 Arena - though the RDS hasn't been ruled out either.
