Ricky Petrucciani continua a faticare nel ritrovare le migliori sensazioni. Impegnato sui 400m del prestigioso meeting di Lucerna, il ticinese non è andato oltre al settimo posto, ma soprattutto ha chiuso il suo giro di pista con un modesto 46"76, quasi mezzo secondo peggio rispetto al suo miglior tempo fatto registrare in stagione.
A illuminare la scena ci ha pensato Shelly-Ann Fraser-Pryce. In 10"82 l'olimpionica giamaicana ha stabilito il nuovo record del meeting sui 100m, in cui ha gareggiato anche Mujinga Kambundji. Sempre alle prese con la fascite plantare, la rossocrociata ha stoppato il cronometro sull'11"24, che migliora l'11"41 fatto segnare all'esordio stagionale ad Athletissima.
