After an almighty struggle in the last round, Jovanovski was again caught napping early on, dropping serve in the opening game.
However, this setback only served to awaken the Serb from her slumber as she reeled off 10 of the next 12 games to take charge of the match.
Hitting confidently off both flanks, there was no let-up as Jovanovski closed in on the second WTA final of her career, breaking Torró-Flor for a fifth time to wrap up a 62 62 win.
"It's the first time I played Torró-Flor who has been having a good run this week," Jovanovski said. "It was a difficult start but after two games I started playing well and felt great with my rhythm and strokes.
"After being here three years in a row, it's a great feeling to now be playing in the final."
Jovanovski was forced to come through qualifying at the Olympic Tennis Complex after missing the cut-off date for main draw acceptance. However, she feels the extra matches have been a help rather than a hindrance. "Entering the tournament late has actually helped me as I got the feel of the courts and also it was good warm up for me after not playing for a while with my wrist injury."
Govortsova had won the pair's previous two meetings and looked the more confident during the opening exchanges, breaking twice on her way to the first set. Minella had her chances in the second - she served for it at 5-4 and had break points for a 6-5 lead - but Govortsova held steady to reach her first final in three years.
"It's a great feeling to reach a final after such a long time," Govortsova said. "It was a pretty easy first set, but in the second set, Mandy started playing more aggressive and also serving well, so I called my coach at the change of ends; he advised me to attack her serve and the strategy paid off as I broke her immediately!"
