MacLennan and Sendel, the reigning world silver medallists in synchro, moved up from fourth after qualifications to claim the silver with a score of 45.600 points, a fraction of a point behind gold medal winners Nadezhda Glebova and Susana Kochesok of Russia with 46.000.
In the women’s individual event, MacLennan placed fifth and teammate Samantha Smith of Toronto was seventh.
“I felt great in the triples but made a small mistake and from there started to travel which cost me a lot of points,” said MacLennan, who completed three triple somersaults in a routine she debuted last November at the world championships in Daytona Beach.
“I need to show this new routine more often in competition in order to stabilize it, it is part of the process and I understand it will take some time.”
Li Dan of China won the gold with a score of 53.315, Yana Pavlova of Russia was second with 54.750 points and Zhong Xingping of China placed third at 53.485.
MacLennan, competed with the most difficult routine in the final but ran into some problems with execution to place fifth with a score of 53.030.
Smith, a finalist for the first time at the 2014 world championships, finished seventh with 51.540 points.
In the tumbling finals Raphaëlle Villotte of Montreal and Erin Templeton of Regina placed fifth and seventh respectively in the women’s competition and Jon Schwaiger of Burlington, Ont., finished seventh on the men’s side.
Schwaiger also competed in the double mini trampoline final of another competition known as the Peter The Great Cup and came away with a silver medal.
“I performed in finals my best passes of the season,” said Schwaiger, noting that the only competitor in the final with a better score was current world champion Mihail Zalomin of Russia.
Sarah Milette of Montreal, also competing in the same event, placed sixth in the women’s trampoline final.
MacLennan and Keegan Soehn, both members of Canada’s Pan Am team, will now focus on their final preparations for the Games next month in Toronto, joining veterans Karen Cockburn and Jason Burnett who stayed at home to fine tune their return to competition from injuries last fall.
