The 21st-ranked Louisiana Ragin’ Cajuns began regional play on a sour note on Friday.

Louisiana fell to the Houston Cougars, 1-0, in the first day of play in the Baton Rouge, La. Regional at Tiger Park.

Savannah Heebner, in a pitchers duel, tossed a 2-hit shutout, to lift the Cougars to the victory.

The loss dropped Louisiana’s all-time record in NCAA Tournament history to 73-58.

The Cajuns, who fell to 16-7 all-time against Houston, is appearing in an NCAA Regional for the 20th-consecutive year, and for the 28th time in the last 29 years.

Houston got on the scoreboard first, plating a run in the top half of the 4th inning, courtesy of a solo home run by Arielle James, her fourth of the season, to give them a 1-0 lead.

That was all the Heebner (26-9) needed, as she held the Cajuns scoreless on two hits, while striking out 2.

UL did have a golden scoring opportunity in the second inning, with runners at second and third with nobody out, but failed to score.

Summer Ellyson (21-9) was the hard luck loser for the Cajuns, allowing only one run on 5 hits, over 7 innings of work.

With the victory, Houston improved to 37-20, overall, while Louisiana dropped to 38-15.

The Cajuns fall into the elimination bracket, where they will face either LSU or Fordham.

First-pitch is scheduled for 2:30 pm on Saturday afternoon.
