Sam Ryan Ziegann meets Li Tu in 1st Round Qualifying at Brisbane 3 Challenger on November 8 on hard court. Ziegann ranks 802nd; Tu sits at 506th. The two have never met.
Ziegann has won three of his last five matches but dropped his most recent outing nine days ago. Tu has struggled lately, winning just two of his last ten and taking no matches in the past two weeks. Both players lost to Enzo Aguiard in recent hard court play, though both beat Keisuke Saitoh on the surface.
Ziegann relies on power from the baseline and will need his groundstrokes to dictate points. Tu plays as a serve-first player whose game revolves around holding serve and capitalizing on break chances. On hard court, Ziegann has posted a 50% win rate while Tu sits at 55%. Ziegann's aggression from the baseline will be tested against Tu's ability to protect his service games and find breakpoint opportunities.
