Rejigging their defensive line helped enforce a productive second stanza from the visitors. With both teams impressing with their flair and vision on attack, it was the Mystics who continued to grow in confidence.
Attacking pair Maria Tutaia and Elisapeta Toeava were the driving force behind the Mystics resilience while shooter Bailey Mes was a key contributor with her aerial skills, athletic ability and accuracy under the hoop.
Bringing the game alive, the visitors briefly nosed their way in front, the Steel having the last say during which Fowler-Reid posted her 600th goal of the season to help the home team steady the ship and take a narrow 37-35 lead into the main break.
Both teams produced a pulsating 15 minutes of play during the all-important third quarter.
The Mystics came out all guns blazing, quickly making up the deficit as they burst into the lead through a mix of patience and exhilarating attacking play. Mes dominated her defenders to play a prominent role as the Mystics strode out to a four-goal lead.
The intensity and pressure produced some uncustomary errors from the normally-slick Steel, who were clearly rattled. However, as is the Steel way, the home team overcame their wobbly patch with a strong finish to claw their way back to a 50-49 lead at the last break and the promise of a thrilling finish.
They delivered on that promise at the end to move to 12 from 12 and lock up a home final, while the Mystics take a bonus point to remain one point outside the playoff race.
