The side's 51-47 win over the table-topping Central Pulse in Invercargill takes it to a seven win, four loss record.
Alongside getting back on track after two consecutive losses, it leaves the Steel well-positioned in a congested ANZ Premiership table.
In second place with four games to go, the side now turns its attention to fourth-placed Waikato Bay of Plenty Magic.
The Magic trails the Steel by five points but it has two games in hand.
However, the Steel can now take plenty of confidence into what looms as another crucial match.
''Massive,'' Selby-Rickit said of the importance of Monday's win.
''I think we were getting a bit worried losing those two games.
''But winning this game, I think there's no excuses any more.
''If we can beat a team as good as the Pulse have been this year, we can pretty much beat anyone.''
Selby-Rickit has been in top form all season, but went to another level on Monday. She and goal keep Courtney Elliott turned over ball regularly against to slow down the Pulse.
A change in tactics to playing a man-on style initially had Selby-Rickit worried, as it was not her strength. However, she said the rest of the team worked well to create the chances for her to be disruptive.
She finished with four intercepts and eight gains, but was quick to play down her own role.
''[The passes aren't] predictable in a way, because the passer can change their mind and pass somewhere else.
''But when your front people do all this work and [the opposition] leave one person kind of standing there wide open, that's obvious.
''But it's not always obvious where the pass is going to go.
''Sometimes you've just got to run and hope for the best, sometimes you miss some, but the ones we got were really good.''
It left her confident the Steel could beat any team, although she was reluctant to jump to talk of defending the title.
''I don't want to jinx it. We literally have to take it a game at a time; it's such a different season to last year.
''Last year we were expected to win, which brings a whole different type of pressure.
''It's not like you go into a game like 'OK we can win this', it was like 'do not lose this, you can't lose'.
''I didn't like it that much. It was a really negative feeling going into games.
''This year it's more positive, like we have to work hard to win, which is a good and a bad thing.
''It was good winning by more last year, but I think it's more character-building this year.''
