As it turns out, third was the charm for Harvard junior Anya Mostek.
After winning the Ivy League title in the 100 back as a freshman in 2023 (52.25), and then again as a sophomore in 2024 (52.15), Mostek took down the Ivy League, Ivy Championships, and Harvard program records on her third try with 52.13, thus eclipsing Bella Hindley's Ivy League and Championships mark by .01.
Mostek took it out in 25.21, which was .12 faster than her first 50 in prelims this morning, but .14 slower than she'd been on the front half in 2024 (25.07).
She came home in 26.92, which not only beat her morning swim by .14 (27.06) and last year's back half by .16 (27.08), but it was just enough to keep a fast-charging Jenna Reznicek of Brown. Reznicek, who won the Ivy crown in this event as a freshman in 2022, went out in 25.57 and closed with 26.68 to notch a PB and Brown program record of 52.25.
And then, as if that weren't enough, she took another chunk out of the newly-established League mark while leading off Harvard's 4×100 medley relay 45 minutes later.
Out in 25.31, she came blazing home in 26.71 to settle the League, Championships, and Harvard records at 52.02.
