Last year?s runner-up Tomas Berdych will kick things off today on centre court against qualifier Marius Copil while Tunisian wildcard Malek Jaziri is hoping he can overcome jetlag to keep up his recent run of good results against Igor Sijsling on Court 2. Jaziri recently hired a new coach, Dejan Petrovic, a former personal mentor for **vak Djokovic and ex-Davis Cup captain for Serbia, and the partnership paid dividends immediately with the Tunisian making the final in the Dallas Challenger earlier this month, followed by a semi-final showing in Morelos, Mexico, last Friday. Petrovic will **t be with him this week and the 137th-ranked Jaziri is hoping their partnership continues to bring him good results for the rest of the season.
