Saturday, Kansas University’s softball team expended a lot of energy mounting a seventh-inning rally against No. 21 Texas A&M.

So Sunday, when the Jayhawks fell behind again, they just couldn’t generate the drive to start a comeback.

In their final regular-season Big 12 game, the Jayhawks lost to the Aggies, 13-0, in a run-rule-shortened five innings at Arrocha Ballpark.

“We didn’t come out as aggressive as we did yesterday,” KU third baseman Marissa Ingle said. “We kind of lacked the want-to and the extra oomph before the game.”

Kansas finishes its Big 12 schedule with a 2-16 record, picking up single victories against Texas Tech and Iowa State.

The Aggies seized their run opportunities, tallying three runs in the second inning on a three-run homer by pitcher Mel Dumezich. An inning later, the Aggies put up a six-spot, capped by a grand slam by third baseman Amber Garza.

Texas A&M didn’t relent, either, scoring three runs in the fourth inning and another in the fifth.

KU starting pitcher Allie Clark (13-9) said it was difficult to keep spirits up when the talented Aggies capitalized on nearly every chance.

“It only takes one pitch,” Clark said. “That’s what sucks as a pitcher. You make one mistake, but that happens.”

Coach Megan Smith sent Clark to the circle for the second day in a row, hoping that Clark would build on the success she had Saturday.

The Jayhawks (31-22) will take on Drake in a home doubleheader at 5 p.m. Thursday, starting a unusual three-series stretch of nonconference games to end the season.
