Here's what you need to know for Thursday:
1. Damian's decathlon
Gold medal favourite and 2014 Commonwealth Games champion Damian Warner enters the second day of the decathlon with a 63-point lead over Brazil's Felipe Dos Santos. Warner, 25, finished first in the 400 metres, 100m and long jump on the first day, and is a good bet to finish with a gold medal when the event concludes with the 1500m at 8:50 p.m. ET. Fellow Canadian Patrick Arbour is in eighth place heading into Day 2.
Canada's Timothy Nedow, who won a silver in the shot put, will also compete for gold in the discus throw. Action begins at the Pan Am Athletics Centre at 10:05 a.m. ET.
2. Field hockey semi
Canada's men's field hockey team will look to make it one step further than the women's squad when it takes on Brazil in the semifinals at 7:30 p.m. ET. Canada, which won a silver medal at the 2011 Pan Ams, has posted a 4-0 record thus far, while the Brazilians have two wins and two losses.
The winner will play in the gold medal match Saturday, where an automatic berth in the 2016 Rio Summer Olympics is at stake. Argentina and Chile will battle it out in the other semifinal.
3. McClintock goes for more
Whitney McClintock, who earned the gold medal in women's water-skiing overall event Wednesday, will look to add to her total in the women's slalom, jump and trick events. The 25-year-old edged out her closest rival, American Regina Jaquess, on Wednesday and will look to do the same in the three disciplines contested Thursday.
Whitney's brother, Jason McClintock, will compete in the men's slalom and tricks events while fellow Canadian Jaret Lllewellyn, who won silver in the men's overall competition on Wednesday, will compete in the jumps and tricks disciplines. The 44-year-old will look to add to his 10 career Pan Am medals. The action on the water begins at 10:05 a.m. ET at the Ontario Place West Channel.
