Seward’s Lydia Jacoby is one step closer to being an Olympic medalist. 

The 17-year-old swimming sensation punched her ticket into the women’s 100-meter breaststroke finals at the Tokyo Olympics with a sizzling semifinal swim Sunday night at the Tokyo Aquatic Center. 

Jacoby won the first of two semifinals and produced the third quickest time on the night with a time of 1 minute, 5.72 seconds. 

Russia’s Tatjana Schoenmaker and the US’s Lilly King — both in the second semifinal — head into tonight’s finals seeded ahead of Jacoby. Schoenmaker posted a 1:05.07 to win the second semifinal just 14 hours after setting an Olympic record time of 1:04.82 in the preliminary round. 

King — the defending 100-meter breaststroke Olympic champion and world record holder (1:04.13) — turned a 1:05.40 to finish second behind Russia’s star.  

Jacoby, the first Olympic swimmer from Alaska, had the second-fastest preliminary time with a 1:05.52.

The finals are at today at 6:17 p.m. ADT.
