Bianca Andreescu: The Canadian teenager announced herself in a big way during the Sunshine Swing, becoming the youngest player in over a decade to win the BNP Paribas Open in Indian Wells and following that up with a fourth-round showing in Miami.
In all, Andreescu boasted a 10-match winning streak in the month, taking out a whole host of WTA stars, and soaring up the WTA rankings into the Top 40.
The teenager scored two notable victories over Angelique Kerber, including one from a break down in the third set in the final to win Indian Wells, Elina Svitolina, Wang Qiang, and Garbiñe Muguruza, among others, in her sizzling spring.
Ashleigh Barty: Barty had a breakout result of her own this spring, as she claimed the other Premier Mandatory title on offer, at the Miami Open.
The Aussie won her first title above Premier 5 level with the victory, racking up a series of impressive wins to leave the tournament victorious, after having never before reached the quarterfinals or better at a Premier Mandatory event.
After defeating Dayana Yastremska and compatriot Samantha Stosur in her first two matches, Barty rallied from a set down to beat Kiki Bertens, and then scored her first career win against Petra Kvitova in the quarterfinals, assuring her Top 10 debut.
She sealed the victory with straight-sets wins over Anett Kontaveit in the semifinals and Pliskova in the final, assuring herself of a career-high ranking of World No.9 as a result.
Angelique Kerber: Three-time Grand Slam champion Kerber checked off a major career milestone in March, as she reached a Premier Mandatory final for the first time at the BNP Paribas Open.
Having not been to the semifinals in Indian Wells since back-to-back appearances in the final four in 2012 and 2013, Kerber knocked off Yulia Putintseva, Natalia Vikhlyantseva, Aryna Sabalenka and Venus Williams to return to the semifinals in the desert, needing three sets to oust both Vikhlyantseva and Sabalenka.
In the semifinals, Kerber cooled off the red-hot Belinda Bencic, ending the Swiss' 12-match winning streak, before being denied her first Premier Mandatory title by debutant Andreescu.
Karolina Pliskova: Having reached the quarterfinals or semifinals a total of seven combined times between Indian Wells and Miami in her career prior to 2019, Pliskova finally broke new ground by reaching the final in Miami.
Pliskova built on another quarterfinal showing in Indian Wells with a run to the championship match in Miami, her first Premier Mandatory final, before she was bested by Barty.
En route, the Czech beat Petra Martic, Alizé Cornet, Yulia Putintseva, Marketa Vondrousova and Simona Halep before being edged by Barty in the final, her second appearance in a final in 2019.
