Grigor Dimitrov had a pretty bad clay-court season so far, losing Madrid and Rome opening rounds. The French coach Patrick Mouratoglou believes that Dimitrov needs to improve on serve in order to play at a high level at the French Open.
'On clay, he lost 24% of his service games, which is one service game out of four', Mouratoglou said. 'And he faced break point the 60% of the time. Dimitrov lacks speed on the second serve, on average he hits the second serve at 152km/h.
Thiem and Zverev serve it 10km/h faster.' Mouratoglou thinks that Dimitrov's elbow on serve is too low. 'In comparison, Roger Federer has quite the similar technique, but he has (the elbow) at shoulder level. The time that Dimitrov loses to get in this position can't be recovered.
He finds himself in an uncomfortable position on second shot: after the second serve, he hits just 23% of his forehands within the court.' ALSO READ: Chris Evert calls for players' protection after Serena Williams' decision
