The Latest on the run-up to the Summer Olympics (all times local to Rio de Janeiro):
Former Clemson Star Brianna Rollins won the 100-meter hurdles at the U.S. Track and Field Championships to earn a spot on the Olympic team.
Rollins, the gold medalist in the event at the 2013 world championships in Moscow, finished in 12.34 seconds. Kristi Castlin was second Nia Ali was third, to also win a spot on the team headed to Rio.
American record holder and 2015 NCAA champion Keni Harrison finished sixth and did not make the team.
"They're going to do great in Rio and make America proud," she said.
Ashton Locklear is providing a pretty compelling case to make the U.S. Olympic women's gymnastics team. The 18-year-old posted a score of 15.750 on uneven bars during the first night of Olympic Trials on Friday night.
Locklear's best bet is to make the team as an uneven bars specialist. She's in a fight with Madison Kocian and Maggie Nichols among others to make the five-woman team when it is announced on Sunday night.
Locklear put her focus on uneven bars and balance beam two years ago after fracturing a vertebrae in her lower back, making floor exercise and vault too taxing.
QUALIFICATION ALERT: Former Clemson star and world champion Brianna Rollins qualified for the Olympics by winning the 100-meter hurdles in 12.34 seconds. Kristi Castlin and Nia Ali also made the team bound for Rio.
Three-time world champion Simone Biles is off to a typical strong start at the U.S. Women's Olympic gymnastics trials.
Biles, the heavy favorite to win the all-around gold in Rio, posted a 16.00 on vault in her first event, her only miscue coming on a short step out on her landing.
Three-time Olympic medalist Aly Raisman was solid on floor exercise with a 15.450 while reigning Olympic champion Gabby Douglas put up a 14.650. Both Olympic veterans are expected to be on the five-woman team when it is named on Sunday night.
Former University of Wyoming All-American Mason Finely won the discus at the U.S. Track and Field Trials to earn a trip to the Olympics.
Finley, who said he's dropped 87 pounds in the past couple of years, won with a throw of 208 feet, 1 inch. Finley lives and trains in Lawrence, Kansas.
Travis Bailey was second with a throw of 202-0 and Andrew Evans was third with a throw of 200-10.
QUALIFICATION ALERT: Former University of Wyoming All-American Mason Finley qualified for the Olympics in the discus with a throw of 208 feet, 1 inch. Travis Bailey and Andrew Evans are also headed to Rio.
American Record holder Evan Jager earned a second straight Olympic trip with a victory Friday night in the 3,000-meter steeplechase at the U.S. Track and Field Trials in Eugene, Oregon.
Jager won in 8:22.48, followed by first-time Olympian Hillary Bor and Donn Cabral, who also made his second Olympic Team.
Jager, a local favorite who lives and trains in Portland, finished sixth in the event at the London Games.
QUALIFICATION ALERT: American steeplechase record holder Evan Jager qualified for a second straight Olympics in the 3,000-meter steeplechase. Hillary Bor and Donn Cabral also will be headed to Rio.
Dawn Harper-Nelson's chance at a third Olympic medal came to a stunning close, when she failed to advance out of the second round of the 100-meter hurdles at track and field trials.
Harper-Nelson, who won a surprise gold in Beijing, then backed it up with silver four years later, finished third in her heat in a driving rainstorm — out of the final set for later Friday night.
She said it wasn't the rain, but simply a sluggish performance, that did her in.
Allyson Felix made it easily through the first round of 200-meter qualifying at Olympic Track and Field Trials, winning her heat in 22.93 seconds.
Felix said her injured right ankle was more or less the same as it has been all week. She won the 400 meters last Sunday and is trying to qualify for the 2-4 double at the Olympics.
The U.S. Olympic Trials in women's gymnastics may really be a race for the last spot on the team.
Barring injury — or an unexpected poor performance — Simone Biles, Gabby Douglas, Aly Raisman and Laurie Hernandez are strong favorites to make the women's team.
Ashton Locklear and good friend Madison Kocian are the leaders in the fight for the fifth spot.
The team will be announced Sunday night.
After four days of rest, Allyson Felix is getting back onto the track for qualifying for the 200 meters at U.S. Olympic Track Trials.
She has already qualified for the 400 and is trying to become the first woman to win the Olympics in both events.
Also up Friday is hurdler Aries Merritt. He captured a bronze medal last August with his kidneys barely operating. He has a new kidney after a transplant and wants to defend his title in the 110 meters. He needs a top three finish in Eugene, Oregon, this weekend to get a chance to do that.
He says he'll go to Rio if he qualifies even though his doctors warned him the Zika virus could pose a threat to his health.
