In "Serving Aces" Alexandra Stevenson and Hugues Laverdière discuss the rise of Emma Raducanu and the new young talent who made themselves known during the Miami Open.  Eala, Fonseca, and Mensik. Alexandra and Ougi talk about Sabalenka winning, the doubles, and Djokovic in the finals - though he lost to Mensik, it was a good tournament for him according to Alexandra.  He paced himself - and really used Andy Murray for coaching advice.  Alexandra explains the PTPA lawsuit as the classic antitrust that is going against the WTA and the ATP - as well as the 4 Grand Slams.  Alexandra discusses March Madness and her "chalk" choices in Duke, Auburn, Florida, and Houston.  Alexandra and Ougi pick Duke to win it all.  For the women, she notes that South Carolina beat Duke and UCLA pulled it out against LSU.  Two more tomorrow.  Alexandra is pulling for UCLA. Ougi is going for South Carolina.
