The Buccaneers fell 4-2 in game one before stumbling to a 12-4, six-inning setback in the finale.
Blinn is now 24-20 overall and 10-10 in the South, where it remains in fourth place.
In the opener, the Bucs fell behind through the first four innings of play before sophomore Emily Kristynik got her team on the board with a two-run home run.
That was all Blinn could muster behind starting pitcher Peyton Welker, who suffered the loss after working six innings of six-hit ball. She allowed three runs, walked four, and struck out three.
Blinn’s offense finished with six hits, led by two for Kristynik.
The Buccaneers started quickly in game two, grabbing a 4-0 edge heading into the bottom of the third frame.
In the top of the first, freshman Alyssa Boozy singled in freshman Erynne Castillo for a 1-0 cushion and freshman Madison Dorrow added a two-run double to make it a 3-0 ballgame. In the third, Kristynik reached on an error that scored Castillo.
Galveston erased its deficit with a seven-run outburst in the home half of the third. The Whitecaps tacked on another run in the fourth, three in the fifth, and one in the sixth to force the run-rule.
The Bucs tallied nine hits, including two apiece for freshman Alayna Calvillo, Boozy, and Dorrow.
Sophomore pitcher Chloee Mason started the game for Blinn but settled for a no-decision. She worked 2 1/3 innings and allowed five earned runs on five hits with a walk.
Freshman Sydnie Cline took the loss after allowing three runs (two earned) on two hits with three walks and one punchout.
Up next, Blinn will host Alvin Community College for a South Zone doubleheader beginning at 1 p.m. on Saturday, April 29, at Hohlt Park in Brenham, Texas. The Bucs will celebrate Sophomore Day as part of the day’s festivities.
Blinn has competed in intercollegiate athletics since 1903 and captured 43 NJCAA national championships since 1987.
