Ostapenko beats heat to oust defending Brisbane champion Pliskova

In the third set of the women's singles match between Elina Svitolina and Karolína Plíšková at the Brisbane International tennis tournament in Australia, Ostapenko was struggling to keep up with her opponent's powerful shots. As a result, she called for assistance from her trainer during the set.

Ostapenko is known for her aggressive playing style and quick reflexes on the court, but Plíšková's superior technique and endurance proved too much for her in this particular match. Despite her best efforts, Ostapenko was unable to overcome Plíšková's strong play and ultimately lost the set 6-4.

It is not uncommon for tennis players to call for assistance from their trainers during matches, especially when they are struggling to keep up with their opponents or need guidance on how to improve their game. Trainers can provide a variety of support, including tactical advice, technical instruction, and physical training.

In the case of Ostapenko, it is likely that her trainer provided her with some tips on how to better handle Plíšková's shots or offered some encouragement to help her stay focused and motivated during the match. However, without more specific information, it is impossible to say exactly what assistance Ostapenko received from her trainer during the third set.
