Grigor Dimitrov has hired Franco Davin as his new coach, Bolamarela reports.
Dimitrov stopped working with coach Roger Rasheed after Wimbledon, while Davin left Juan Martin Del Potro's team in July. Davin began coaching Del Potro in 2008, but the 2009 U.S. Open champion has been dealing with a serious wrist injury lately, playing just two tournaments this year after just four in 2014.
Dimitrov reached a career-high No. 8 last season and made the Wimbledon semifinals. But 2015 has been a challenging follow-up. Currently ranked No. 19, Dimitrov has only reached two quarterfinals at Masters-level tournaments (Monte Carlo and Madrid), and has played in just two semifinals at ATP 250-level events.
Dimitrov will play Kuala Lumpur next week.
