who won the previous day's stage,
picked up a two-second bonus by winning an intermediary sprint, but did not feature in the day's finale.
"I was supposed to be his leadout man but he wasn't feeling so great," said Boasson Hagen.
Germany's Andre Greipel was second with Matthew Goss still in the overall lead.
who switched to Sky from the now-disbanded HTC-Highroad team in October,
said Boasson Hagen could also be a contender for the season's opening single-day classic - the Milan-San Remo - on 17 March.
"It was better for Boasson Hagen today. The team is strong. It could be me or it could be him,'' he said.
The Tirreno-Adriatico ends on Tuesday with a 5.78-mile individual time trial in San Benedetto del Tronto, on the Adriatic coast.
