Danville-resident and Cal grad Dana Vollmer will come home with at least two medals from the 2016 Rio Games.
On Sunday night, she took bronze in the women's 100-meter butterfly final with a time of 56.63 seconds. Vollmer won Gold in the same event in the 2012 London Olympics.
Dubbed the "Momma on a Mission," Vollmer swam in the Rio Games more than 15 months after giving birth to her son.
Vollmer won silver on Saturday night in the women's 4x100m freestyle relay.
During the semifinals Saturday night, Sweeden's Sarah Sjostrom, the reigning world champion, set the Olympic Record in the 100m butterfly but missed her own world record by about two-tenths of a second. Sjostrom clocked 55.84 to advance to Sunday’s final in first place.
Vollmer, the 2012 Olympic champion in the event, qualified for the final with a fourth place finish of 57.06 seconds.
Fellow American Kelsi Worrell missed the final by 0.03 seconds, finishing in ninth place.
Vollmer, Team USA Take Silver in 4x100m Freestyle
Vollmer also helped Team USA women win silver in the 4x100-meter freestyle relay Saturday night.
The Australians, let by a sister act, set a world record in the relay to beat the American squad anchored by Katie Ledecky.
Simone Manuel and Abbey Weitzeil put the United States ahead at the midway point Saturday night, but Bronte and Cate Campbell were simply too strong on the final two legs. Younger sister Bronte surged past Dana Vollmer before handing off to Cate, who pulled away from Ledecky to win in 3:30.65 seconds -- breaking the mark of 3:30.98 the Aussies set two years ago.
The U.S. had to settle for silver in an American-record time of 3:31.89, extending a gold medal drought in the event that goes back to the 1996 Atlanta Games.
Canada took the bronze in 3:32.89.
Vollmer won a gold medal at the 2004 Athens Olympics (4x200m freestyle relay) and three more golds at the 2012 London Olympics (100m butterfly, 4x100m medley relay, 4x200m freestyle relay).
Media reports surfaced that she ended her competitive swimming career after taking time off to give birth to a son, Arlen, in March 2015, but she never officially retired.
Vollmer returned to the pool six weeks later in May, and won a winter national title by December, following all that up with her third place finish in the 100m Butterfly in Rio.
