".....PINE BLUFF, Arkansas -- How about this for perfection by North Texas softball pitcher Hope Trautwein - 21 batters faced, 21 strikeouts.
Trautwein threw the perfect game Sunday, striking out all 21 Arkansas-Pine Bluff batters she faced in a 3-0 victory.
It was the first perfect game in North Texas history, and is believed to be the first perfect seven-inning game in NCAA Division I history with every out being a strikeout.
NCAA records list two other pitchers with 21 strikeouts in a seven-inning game, but neither of those were perfect games. Alabama's Alexis Osorio had a 21-K game against Fordham in 2018, and California's Michele Granger did that against Creighton in 1991.
