It was a battle for the bronze medal for Canada's Jennifer Abel and Italy's Tania Cagnotto. The Italian diver made an impressive dive that gave her a 6.45 point lead and landed her a silver medal.
Cagnotto did a reverse 2.5 pike that garnered 81.00 points. She made a 372.80 in total.
The Italian diver was very happy with her dive and after the posting of her final score gave her father Giorgio Cagnotto a big hug. Her father was also a diving medalist.
Canadian diver Abel finished fourth and did not get a medal.
Abby Johnston of the U.S.A. did not get any medal and finished last in the ranking. Johnston gave impressive attempts during the preliminary on Friday and semi-finals on Saturday.
She only totaled 302.85 during the 3-meter event on Sunday.
"I wasn't nervous on any of them, so I kind of approached each one the way I normally do," Johnston said.
She added, "Sometimes you miss and sometimes you hit. Bad dives happen to good people. I felt like I had a really strong top on everything and gave myself the best chance, but I wasn't where I wanted to be on the bottoms of my dives. I'm really proud of how I performed and how I carried myself throughout the Games."
The American diver will be going back to medical school and will be planning for her upcoming wedding.
"I start school nine days from now and will be doing my (medical school) rotations and planning a wedding. I have a lot to look forward to and am happy to close this chapter of my life," the diver said.
