Taylor will be available for the first two and last two matches of the season, plus finals if required, with Winfield strengthening the batting line-up during Taylor’s absence.
An exciting top-order batter and off-spinner, Taylor is currently ranked the no.3 T20I allrounder on the ICC Player Rankings list.
Taylor, 28, joined the Sydney Thunder ahead of WBBL|01 and played 58 games in green, including the club’s title-winning final in the inaugural WBBL season.
Last summer, she was the Thunder’s leading wicket-taker with 19 at an economy rate of 6.92, while also scoring 212 runs at 35.33 and becoming one of just four Thunder women to surpass 1000 career Big Bash runs.
The right-hander compiled 205 runs at an average of 41 from just six matches in her recent Kia Super League campaign for the Southern Vipers in the UK.
In 2013, the powerful right-hander became the first player in history (male or female) to reach number one on the ICC Player Rankings for ODIs and T20Is simultaneously.
“I’m very much excited about WBBL (this year), especially in a new environment,” said Taylor, who is the leading runscorer for West Indies in both formats of the game.
“I don’t know much about the team, but I am mostly looking forward to playing alongside Suzie (Bates) and Sophie (Devine). And my favourite colour is blue!”
England batter Winfield has experience in the WBBL competition, having spent two seasons with Brisbane Heat and one with the Hobart Hurricanes.
She will enter WBBL|05 fresh from captaining the Yorkshire Diamonds in the Kia Super League, where she opened the batting alongside Sydney Sixer Alyssa Healy, producing a strike-rate of 102.25 from 10 games.
Winfield has played three Tests, 42 ODIs and 32 T20Is for England and is also an experienced wicketkeeper.
She scored the most runs for England in the T20 component of this year’s Women’s Ashes series, averaging 35.50 from the three matches.
The 29-year-old was a recipient of one of the first central England Cricket contracts for female players in 2014 and went on to be part of the winning England side at the 2017 ICC Women’s Cricket World Cup.
“Adelaide has always looked like a club with a fantastic culture, both in the women’s and the men’s,” Winfield said.
“It will certainly be nice to play alongside Megan Schutt rather than having to face her hooping in-swingers!
“Joining a new team is always exciting and I can't wait to get stuck in. I just hope to score as many runs as I can, contribute to the group and ensure we make finals.”
SACA General Manager, High Performance Tim Nielsen said: “Stafanie and Lauren are welcome additions to the Strikers and will add significant depth to our batting and bowling ranks.
“Both have impressive playing histories and we’re thrilled to attract international players of such high calibre to Adelaide; it really speaks volumes of the environment that we’ve created here.
“Both players have significant leadership experience that will be valued on and off the field, particularly in continuing to develop some of our younger local players.”
The Adelaide Strikers begin their WBBL campaign on Saturday, 19 October at Karen Rolton Oval in Adelaide.
