The pace of the peleton quickened ahead of the category three climb to Mur de Bretagne, with the gap to the front shortening to under a minute with 20km to go.
When is the next stage of the Tour de France?
"I'm happy with that", he said.
"My first thoughts are that I hope my wife hasn't gone into labour", smiled Martin as he caught his breath.
During his chase back to the peloton, Dumoulin took a long draft behind his team vehicle but race commissaires deemed it too long - and deducted a further 20 seconds from his time. "I managed to keep my sprint longer". "I'm disappointed of course, I would have liked to be in a better position on (general classification) but that's how it is".
Dumoulin, the time trial world champion and 2017 Giro d'Italia victor, started the stage 44 seconds ahead of Froome, but finished just behind him. Froome trails race leader Greg Van Avermaet by 1:02. Dumoulin is one more second behind.
"Then I had to chase and that effort was fatal".
Coming up: Partial solar eclipse on Friday the 13th
Speaking to his more than 250,000 followers Mr Begley said: "Coming up this Friday the 13th will be a partial solar eclipse ". Who can see the partial solar eclipse? A solar eclipse has not fallen on a Friday the 13th since December 1974.
"It's not the first time we have lost a rider on the Tour de France and it won't be the last time either, I guess".
Martin broke away at the midway point of the straight two-kilometer ascent of the Mur de Bretagne, winning the 181-kilometer (112-mile) leg that started in the western port city of Brest in over four hours.
"But when I went to go, Quick-Step and Bora have just got a different kind of level of top speed. It was good to finish second back then but this time I was coming for victory", said Martin. "My team did a brilliant job all day and I wanted to finish it off", he said.
Van Avermaet, a support rider for Porte, has held the yellow jersey since BMC won the team time trial on Stage 3.
Martin was one of several team leaders along with former Tour victor Vincenzo Nibali and two-time runner-up Nairo Quintana who were caught off-guard by an attack by Quick-Step midway through the stage during a straightaway that was exposed to crosswinds.
With a nervous day expected on Sunday's cobbled stage nine to Roubaix before the race even moves to the Alps, Thomas said it was too soon for anything to be decisive.
The slightly-built Bardet's AG2R team will have to race 17 stages of the 2018 Tour a man down after an over-curious roadside fan stepped into the path of the onrushing peloton to take a photo.
