The pair finished safely in the peloton in Fermoselle as action resumed following the opening rest day. The day always looked likely to play into the hands of the sprinters and so it proved, with Elia Viviani (Quick-Step Floors) pulling off a comfortable victory.
Finishing alongside each other in the bunch, De La Cruz and Kwiatkowski retained 13th (+1:26) and 15th place (+2:10) respectively.
The final run-in saw a number of punctures among the general classification contenders, with Nairo Quintana (Movistar), Wilco Kelderman (Team Sunweb) and race leader Simon Yates (Mitchelton-Scott) all managing to return to the safety of the peloton.
With a return to the hills on Wednesday, Sport Director Gabriel Rasch explained that a more straightforward day was used to help conserve energy.
He told TeamSky.com: “It could have been really different out there if it was windy but that didn’t turn out to be the case. For us it was just about staying safe in the peloton, avoiding any problems and trying to recover further.
“Tomorrow is a really hard stage. It doesn’t look that bad on paper but we know at least the last 50km from 2016. Today was more about getting ready for tomorrow really.”
