Dumoulin never looked to be in trouble on the rain-soaked 209-kilometre stage to Montevergine di Mercogliano, crossing the line in 11th place. He remains second overall.
However, the Giro's defending champion did not seem any more upbeat than he was after the Etna summit finish three days ago, where he had told reporters his performance had been "not good, but not bad."
"I didn't have the best of days," Dumoulin told reporters afterwards. "I'm happy not much happened today and that it wasn't a GC stage. I'm looking forward to the stages further on in the race."
Dumoulin said he had been riding close to Chris Froome (Team Sky) when the four-time Tour de France champion fell for the second time in this year's Giro d'Italia. Whilst Froome's crash appeared to be minor, Dumoulin came through completely unscathed.
"[Chris] Froome (Team Sky) was just ahead of me when he crashed. I brushed against him a bit when that happened, but I could stay on my bike," Dumoulin recounted.
Dumoulin and the rest of the Giro d'Italia peloton will face a much bigger challenge on Sunday with the ascent of the summit finish of the Gran Sasso in central Italy, and a final segment of the stage that features around 45 kilometres of relentless climbing. For now, though, the Dutchman seems simply happy to ticked off another day of racing.
