The Renegades all-rounder made her debut for Australia in the tri-series T20 opener against India.
Australia reeled in the home side’s score of 152 with 11 balls to spare.
Molineux conceded 15 runs from her two overs and took three catches including the dangerous Smriti Mandhana who was looking ominous on 67 from 41 balls.
“I was quite nervous, I think that’s to be expected though,” Molineux said.
“Meg throwing me the ball - I was really lucky, she just backed me in and so did the rest of the staff and the girls – so it was a great day.
“Mandhana was on today so I couldn’t drop that one … I was lucky it stuck in my hands.
“I just hope to play my role for the team and if the ball came to me I just tried to get something behind it because it’s such a quick outfield.
“It kept following me today, so lucky it turned out well.”
Before the match, Molineux was presented with T20I cap number 48 by assistant coach and fellow left arm spinner Shelley Nitschke.
“It was pretty special, I actually got a tear in my eye,” Molineux said.
“It’s obviously a dream of mine and to be able to be here in India and to have my cap presented by Shelley – who is someone I always looked up to and have enjoyed working with over here – it was a pretty special moment and I’ll remember it very fondly.”
Molineux, 20, played all 14 games for the Renegades in WBBL|03 after being named Betty Wilson Young Cricketer of the Year Award in January 2017.
“We’re really lucky in Australia with the WBBL – it’s exposed me to this level of cricket and playing against international cricketers from a young age.
“It’s made the transition a little bit smoother.”
Australia will play England twice and has another match to come against India with the two highest ranked sides meeting in the tri-series T20 final on March 31.
