Cason Adams threw the second no-hitter in UT Tyler baseball history Saturday at Irwin Field.
Adams, a sophomore from Rockwall, held Hardin-Simmons in check as the Patriots scored a 4-0 seven-inning victory.
Adams was almost perfect in the game, allowing just two batters to reach base on walks.
He struck out nine on for UT Tyler's first no-hitter since 2006, when Kevin Dutcher pitched one against Paul Quinn in a 10-0 UT Tyler win.
The Patriots scored an 8-5 win in the second game to improve to 17-8 overall and 13-5 in American Southwest Conference play. The Cowboys fall to 6-14 and 2-9.
UT Tyler will return to action on Tuesday as it hosts nonconference foe Jarvis Christian at 6:30 p.m. at Irwin Field.

The Patriots' Logan Tucker added two more runs in the fourth with a two-run single, making the score 4-0 UT Tyler over the Cowboys
Coover and Buddy McCoy belted solo homers in the first.
In the third, Zack De Luna brought the Cowboys within 2-1 on an RBI double. An inning later, Cody Berryman and Jared Jacques gave HSU the 3-2 lead on a pair of RBI singles.
The Patriots answered with four runs in the bottom of the fourth to take a 6-3 lead. Alex Bishop had a two-RBI double, while Sam Lane scored on a wild pitch, followed by Derick Smith's sacrifice fly.
Hardin-Simmons would make things interesting in the sixth, as Berryman knocked in another run with a single and Jacques scored another run on a fielder's choice.
Leading just 6-5, the Patriots' offense got two big runs, as McCoy blasted his second home run of the game in the seventh. Lane then singled in Bonnin for an 8-5 advantage.
