PARIS – Carmel High School swimmer Alex Shackell is set to win a second medal at the Paris Olympics.

She swam the butterfly leg in the 4x100-meter medley relay Saturday, qualifying Team USA for Sunday’s final.

She is eligible for any medal won in the final, in which the United States should be favored, featuring world record-holders on the first three legs. Shackell, 17, is entering her senior year of high school.

On Thursday, she swam in heats of the 4x200 freestyle relay, in which the United States took a silver medal. She became the second Indiana girl to medal at an Olympics while still in high school, standing on the podium during the medal ceremony.

Earlier that night, Shackell finished sixth in the 200 butterfly.

In the medley relay heats, Australia had the top time of 3:54.81. The United States was fourth in 3:56.40.

Relay swimmers were Katherine Berkoff, backstroke, 58.98; Emma Weber, breaststroke 1:07:39; Shackell, fly, 57.32; Kate Douglass, freestyle, 52.71.

Of the 16 swimmers on the butterfly leg, Shackell’s time was seventh.

In the final, the Americans have world record-holders in backstroke (Regan Smith), breaststroke (Lilly King) and butterfly (Gretchen Walsh). On freestyle is Torri Huske, the silver medalist at these Paris Olympics.

Alex’s father, Nick, was on Great Britain’s 4x100 medley relay team at Atlanta in 1996. A week ago, Alex’s brother, Aaron, finished eighth in the 400 freestyle.

Only other Indiana girl to medal while still in high school was Fort Wayne Snider’s Sharon Wichman at the 1968 Mexico City Olympics. She won gold in the 200 breaststroke and bronze in the 100 breaststroke.
