HOUSTON — Jacob Campbell doubled in the bottom of the, ninth driving in Josh Vidales with the winning run as Houston defeated Tulane 4-3 at Cougar Field.

Vidales led off the Cougars’ ninth with a single to center. Chris Iriart sacrificed him to second bringing Campbell.

Campbell sent the first pitch from reliever Patrick Duester down the line in left for a walk-off double.

No. 22 Houston (22-12, 3-4 American Athletic Conference) had taken a 3-2 lead in the sixth with the help of an error by Tulane (21-13, 2-5). Corey Julks had an RBI single to right, and Kyle Survance added a sacrifice fly to left field.

Tulane tied the score at 3 in the top of the seventh when junior Richard Carthon slapped a single into right field to score senior Garrett Deschamp from second base off Houston’s Andrew Lantrip.

Houston held a 1-0 lead lead after scoring in the bottom of the fourth, but Tulane tied it on sophomore Jake Willsey’s first career triple, scoring fellow sophomore Jake Rogers.

The Green Wave then took a 2-1 lead in the sixth on a heads-up play by sophomore Stephen Alemais, who broke from third after a throw to first on a dribbler right in front of the plate off the bat of senior John Gandolfo. However, Houston battled back in the bottom of the sixth to put two on the board.

Tulane starter Corey Merrill allowed six hits and three runs (two earned) in 5.1 innings of work. Junior Patrick Duester relieved Merrill, pitching the final three innings.

Duester (4-3) only allowed two hits on the night — but the second one proved to be crucial, as it scored Vidales for the winning run.

Duester fanned two while also walking two. Willsey led the team with a 2-for-4 performance. Willsey, Carthon and Gandolfo collected RBIs on the evening. Alemais doubled in the sixth before scoring his run.

Houston’s Patrick Weigel was credited with the win after pitching the final 2.1 innings. Weigel (3-0) struck out two. Lantrip allowed seven hits and fanned five during the first 6.2 innings.

Junior Emerson Gibbs (3-0, 2.05) will start for Tulane when the series resumes at 2 p.m. Saturday. The game was moved up to avoid potential rainy weather Saturday night.

Houston has not yet named a starter for Saturday’s game.
