Doyle claimed the final place on offer in today's final after recording the eighth fastest time during yesterday's semi-finals.
That race is due to start shortly before 7pm.
But before that, there's plenty of Irish interest in this morning's Heats.
Brendan Hyland goes in the 200-metre Butterfly while Sycerika McMahon returns to the pool for the heats of the 200-metre Individual Medlay.
Nicholas Quinn and Dan Sweeney are both competing in the 200-metre Breaststroke while Danielle Hill goes in the 100-metre Backstroke.
Also, Shane Ryan will also be back in the pool after competing in the final of the 100-metre Backstroke last night – the American-born swimmer will be in action in the heats of the 50-metre Backstroke.
