What happened to Gulbis tennis?
What happened to Gulbis tennis? Gulbis lost six consecutive tour-level matches from mid-February to mid-May and seven consecutive from mid-May to late July. A back injury forced him to retire from his final two tournaments. But this year, Gulbis is free of the back spasms that bothered him, and he credits a long off-season for his rejuvenated start.
