For Antonietta Di Martino the change of coach, from Davide Sessa to Massimiliano Di Matteo, in 2009 marked a resurgence in her form. She won the Italian Indoor Championships, but illness ruled her out of the 2009 European Indoor Championships a few months later. She took bronze at the 2009 European Team Championships and, soon after, she beat Blanka Vlašić to win the Golden Gala meeting, jumping 2.00 m in Rome. She cleared 1.99 m at the 2009 World Championships in Athletics, securing a fourth-place finish. She capped off the year with a bronze at the final edition of the World Athletics Final and married her new coach Di Matteo.
