Conversations with Alexandra Stevenson on "Serving Aces" with co-host Hugues Laverdière talk about Roger Federer and his commencement speech at Dartmouth University, commanding the graduate audience with his timely discussion of life being bigger than a tennis court.  He is now Dr. Roger Federer, with a Doctorate in Humane Letters.

Alexandra brings in the Tony Awards to the conversation, discussing the big musical winner, "The Outsiders." Fascinating moments from Alicia Keyes, Jay Z and Hillary Clinton.

Ougi discusses the US Open Golf tournament.

Alexandra gives Ougi a tutorial on what makes up a grass court - and indeed, takes him back 50 years to Robert Twynam, the venerable Wimbledon groundskeeper.  Grass today is 100 percent rye, something that Alexandra says is noticeably different from her days of playing on fast grass.
