Meylan vs. Prystajko — A Top-25 Ace Duel In Stillwater

Our Pick
Oklahoma State
UPSET WATCH

Ruby Meylan is the Big 12 Co-Pitcher of the Year (26 wins, 2.03 ERA, 213.2 IP). Stanford's Zoe Prystajko is a genuine Top-10 nationally arm — 19-5, 2.52 ERA, 167 K (ACC strikeout leader), 0.99 WHIP — with Emily Jones hitting .424. This is the duel-of-aces regional. Princeton brought a 5th-straight Ivy title and tournament MOP Cassidy Shaw. Stillwater is the host but it's a TOSS-UP.

X-Factor

Whoever wins the likely Game 2 between Meylan and Prystajko stays in the winners' bracket. Stillwater's crowd gives OK State the edge — but Stanford's regional ceiling is genuinely Super Regional.
