Yates was able to extend his overall lead to 47 seconds to Dumoulin, but appears likely to need a larger cushion with the Dutch rider expected to gain time in the individual time trial later in the race.
Of greater concern to Yates is the form of Dumoulin who, although beaten yesterday, proved the only rider capable of staying relatively close to the 25-year-old, chasing him doggedly all the way to the line and finishing just two seconds behind.
The stage was raced on a hilly route over 156 kilometres from the central city of Assisi across to Osimo near the Adriatic coast. That leaves the four-time Tour de France victor 23rd overall and a huge three minutes and 20 seconds off his fellow Briton.
Stage 12 is a 214km ride to Imola.
"I'm in a position where I need to gain time".
With the loss, Froome slid back two spots to 12th overall at 3-20 minutes behind Yates.
"I certainly haven't given up hope, " Froome said.
Everton sack manager after six months in charge
Watford "remain furious" that Everton's interest past year unsettled Silva and a poor run of form led to his sacking in January. According to a report in the Daily Mirror, Marcel Brands has already made bringing Marco Silva to Everton his top priority .
"I'm going to keep fighting, it's good to get this racing in the legs".
Yates now leads by 41sec from Dumoulin with Pinot third at 46sec.
"It's not just me and Tom", Yates said.
France's Thibaut Pinot would end eight seconds adrift of Yates on the stage, which took place in the hometown of the late Michele Scarponi, who was killed in a training ride past year. Dumoulin came the closest to getting on his wheel, but in the end, all the favourites were distanced, with third-placed Thibaut Pinot and fourth-placed Domenico Pozzovivo losing eight seconds, and fifth-placed Richard Carapaz coming in alongside Bennett, 23 seconds down. That was a really tough finish.
Just over 30km into the race Astana Pro's Luis Leon Sanchez (Spain), BMC Racing's Alessandro De Marchi (Italy), Androni Sidermec-Bottecchia's Fausto Masnada (Italy), Bardiani CSF's Mirco Maestri (Italy) and Wilier Triestina-Selle Italia's Alex Turrin (Italy) broke clear from the peloton.
"I'm not going to lie it took a whack out of me that crash before the start over in Jerusalem, I've had a lot of pain down my right-hand side".
"Really hard but happy I could get more time". The race ends in Rome on 27 May.
