PRAGUE (AP) Tomas Berdych says he has fired his coach Dani Vallverdu after a 17-month partnership.
Berdych's announcement comes days after a 6-0, 6-0 loss to David Goffin in the third round of the Italian Open.
In Monday's statement, the eighth-ranked Berdych says the move is a reaction to his unimpressive recent form. He is 19-10 in 2016.
Berdych says ''I am not a player at the beginning of my career, so I had to act quickly when I felt like making a change.''
The 30-year-old Berdych led the Czechs to two Davis Cup titles but has never won a Grand Slam tournament. He was a runner-up at Wimbledon in 2010 and reached his highest ranking at No. 4 a year ago.
Berdych has yet to decide on Vallverdu's replacement.
