In the men's 50 butterfly semifinals, Finlay Knox set a Canadian record of 23.25 seconds but it wasn't enough to qualify for Monday's final at 11:46 a.m. ET.

The 23-year-old from Okotoks, Alta., finished 1-100th of a second behind the eighth and final qualifier, Inchul Baek of South Korea, while American Michael Andrew was the top qualifier in 22.94.

"I had no expectations, just went in there and had some fun," Knox told Diving Canada. "Obviously, a little bitter I came ninth [and will miss the final] but the goal wasn't the 50 [but] prep for the rest of the week, so very happy."

Earlier Sunday, Knox swam with the men's 4x100 freestyle relay team that finished fifth in its heat and 11th overall in 3:15.74 but didn't advance to the final.

The 200 individual medley, which he won at the Pan Am Games last October in Santiago, Chile, is the main focus in Doha. He will also compete in "a few relays" and the 100 fly.
