Swiss No. 2 Stanislas Wawrinka, who clinched a Davis Cup tie for Switzerland against Australia on Monday, announced on his Facebook page that he was splitting from coach Peter Lundgren.
The two began working together in July 2010 and Wawrinka was vocal about his goal to crack the top 10 again. He got as high as No. 13 in April, but has slumped since then, settling in at 19th this week. Wawrinka, who has yet to name a new coach, thanked Lundgren in the Facebook message:
I need to let my fans know Peter Lundgren and I won't be working together anymore. He played a major role in my career and I am deeply grateful. We have had a lot of success and fun working together, I can't thank him enough.
