The long-awaited first head-to-head meeting between world No. 1 Ashleigh Barty and No. 9 Bianca Andreescu will finally take place on Saturday when the two players collide in the 2021 Miami Open women's final at Hard Rock Stadium in Miami Gardens, Fla. Both the 24-year-old Barty and the 20-year-old Andreescu have been fixtures in the top 10 for the past two years. But the coronavirus pandemic and a left knee injury for Andreescu helped prevent the two from facing off until Saturday.

The match is set to begin at 1 p.m. ET. William Hill Sportsbook lists Barty as a -187 favorite (risk $187 to win $100) in the latest Barty vs. Andreescu odds, with Andreescu listed at +160 as the underdog. You can also pick whether Barty will cover the 2.5-game spread and how many games the match will last, among other wagering options in the 2021 Miami Open odds. Before making any Andreescu vs. Barty picks, be sure to see the 2021 Miami Open predictions from elite tennis handicapper Gavin Mair.

Mair is the international women's tennis expert who called unseeded Jelena Ostapenko (80-1) winning the 2017 French Open, Naomi Osaka (32-1) winning the 2018 U.S. Open and Andreescu (20-1) winning the 2019 U.S. Open. Before the women's singles final in the most recent grand slam, the Australian Open, he picked Osaka to win in straight sets (-162) and for the match to go Under 20.5 total games (-118), and he was right on both counts.

And on Thursday he went a perfect 4-0 with his wagers across the two semifinals, including correctly calling that both Andreescu and Maria Sakkari would win a set at +130.

Now, Mair has broken down the latest 2021 Miami Open women's final odds and released his coveted best bets for Barty vs. Andreescu. He's sharing his picks and analysis at SportsLine.

Andreescu has the kind of game that could give Barty fits. The Canadian has an array of shots -- from moon balls to slice forehands -- that she is not afraid to use at any time. "Andreescu plays an intelligent game, mixing both power and delicately controlled shots to puncture holes in the opposition," Mair told SportsLine.

In addition, Andreescu has shown she is plenty fit despite not playing a match between November 2019 and February 2021 because of a left knee injury and the pandemic. Each of her last four matches in Miami has gone three sets. And on Thursday night she outlasted Maria Sakkari in a two-hour, 42-minute, three-set marathon that did not end until 1:35 a.m. ET.

Mair is leaning over 22.5 total games, and his other picks include a play on the outright winner and how many sets the match will go. Be sure to see Mair's picks and analysis before making your Miami Open 2021 picks for the women's finals.
