The 30-year-old last won on European soil at last year's Giro Rosa on stage 9 but has been in imperious form this season at home in the states with overall victory at the Tour of the Gila, second at the Redlands Bicycle Classic and the mountains classification at the Women's Tour of California.
"It's wonderful to be able to win, and it's wonderful to be able to pay back some of the trust that the girls have put in me so far," Abbott said of Wiggle-High5's second stage win of the race after Chloe Hosking's stage 3 success. "We've got four more days to get this done, so we're not taking anything for granted yet.
"We've still got four stages more to go," Abbott said of her overall race lead. "The goal is to finish in it, not just to wear it, so we've still got a lot of work to do!"
Abbot made her race winning move on the early slopes of the Mortirolo, powering past the break who would be the last riders to see her until the finish line besides crashing at one point.
"I pretty much went straight from the bottom and tried to take it as steady as I could for myself, to just go my pace and see where I could end up," she said. "A break was gone, but I went past them; so the break didn't last very long.
"There was a plateau for a while, and then some rollers. And on the first descent of the rollers I actually crashed… pretty badly, which was not really part of the game plan. I hit a big hole - there were a lot of those to look out for - but I was able to get back up and keep going. My bike was kind of messed up, but it worked.
"Then it was just a matter of getting my head back round to where I was, and really trying to focus myself, after landing pretty hard I had to get myself down the rest of the descent."
Abbot now leadsMegan Guarnier of Boels Dolmans by 10 seconds, teammate Elisa Longo Borghini by 15 seconds and Claudia Lichtenberg (Lotto Soudal Ladies) by 33 seconds. Stage 6 of the Giro Rosa is 118.6km from Andora - Alassio to Madonna della Guardia.
