Why it matters for Nathan Adrian

Adrian's comeback story is different from others, having been diagnosed with testicular cancer two and a half years ago and undergoing two surgeries. He entered Olympic Trials ranked eighth in the U.S. in the 100m free since the start of 2019.

What comes next?

The men's 50m freestyle final is set for 8:15 p.m. ET on Sunday. Adrian will face tough competition, including world champion Caeleb Dressel, who swam 21.51 in the semis, and Michael Andrew, who went 21.55.

Manuel finished ninth in the 100m free on Thursday and disclosed an overtraining syndrome diagnosis in March, taking three weeks out of the pool, and depression. She was pleased to swim 24.50 seconds in her Saturday semifinal of the 50m free.

Adrian's faster time from prelims, 48.37, would have qualified fifth into the eight-man final. He said he threw a little bit more emotional energy into prelims than he should have.

Adrian, 32, got married and became a father since the Rio Olympics. He said having a family has helped him let go of bad practices immediately and focus on his loved ones.

The U.S. Olympic Swimming Trials will conclude on Sunday, with the men's 50m freestyle final being one of the last events. Nathan Adrian will look to make a strong finish and secure a spot on the Tokyo team.
