The University of Bath-based athlete set a winning time of 54.09 as she claimed her second Diamond League success of the season, moving her back to the top of the overall standings.
“I’m absolutely delighted,” said Doyle, who is coached by Malcolm Arnold at the Sports Training Village (STV).
“It wasn’t even a great race – the last hurdle was very poor, so I think there’s a lot more to come. If I get it right, I can definitely go sub 54 seconds.”
The Diamond League action moves to London on July 22-24 when the Queen Elizabeth Olympic Park hosts the Muller Anniversary Games.
Andrew Pozzi, Doyle’s training partner, is scheduled to compete in the 110m hurdles against two University of Bath graduates, Lawrence Clarke and David King, the latter coached by James Hillier at the STV.
European Championships silver-medallist Jazmin Sawyers, who also trains at the University, goes in a star-studded long jump competition that features Olympic and World Champion Jessica Ennis-Hill and fellow heptathlete Katarina Johnson-Thompson.
The IPC Athletics Grand Prix Final is also taking place at the Anniversary Games on Saturday and will see Sophie Kamlish – coached by Rob Ellchuk at the STV – take on World Champion Marlou Van Rhijn in the T44 100m.
