Sam Oomen was not at the start of the fifth stage of Itzulia Basque Country on Friday, with the team saying he was not well. It is another unwelcome addition to the Team Sunweb sick-and-injured list, leading to questions as to which teammates will be able to support Tom Dumoulin in the Giro d'Italia.
