Moments after Hyeon Chung pulled out of his Australian Open semifinal because of blisters, ensuring Roger Federer would reach a 30th Grand Slam singles final, Boris Becker joined Catherine Whitaker and David Law on the Tennis Podcast to look ahead to Sunday’s clash with Marin Cilic. The two-time champion also previews the women’s final between Caroline Wozniacki and Simona Halep, explains why he left the stadium immediately after match point in the 1991 final, and predicts how a peak Becker would have done against Federer.As well as Becker, Catherine Whitaker and David Law are joined by Mary Carillo, who was voted by listeners as the podcast’s favourite guest of 2017. A former player and feted broadcaster in the United States for her work on tennis, documentaries and coverage of the winter and summer Olympics for NBC, Carillo talks about her reaction to Chung’s decision to retire mid-match, her expectations for the men’s and women’s finals, and the documentary she has produced about Margaret Court. On Saturday, the women’s final will be broadcast live on Eurosport, with coverage starting at 8am UK time. BBC Radio 5 Live Sports Extra will carry commentary from 8.30am. The Tennis Podcast is produced daily throughout the Australian Open, presented by Catherine Whitaker (Eurosport) and David Law (BBC 5 Live), in association with Telegraph Sport and Eurosport.  See acast.com/privacy for privacy and opt-out information.
