SAN ANTONIO — Jonathan Dziedzic struck out nine batters and Lamar scored in four consecutive innings, including four times in the sixth, and the Cardinals claimed this weekend's series opener with UTSA, 9-4, on Thursday at Roadrunner Field.
Dziedzic (5-4) allowed four runs (two earned) and scattered seven hits in 8.2 stanzas.
Meanwhile, Darian Johnson and Garret Autrey each collected three hits and Seth Dornak drove in three runs to lead Lamar's 14-hit attack.
The Cardinals (21-29, 13-18 SLC) opened a 5-0 advantage after the first five frames, which included a three-run third to break open the scoring seal.
Dornak hit a two-run homer to start the scoring in the third for Lamar, while Brad Picha added an run-scoring double.
A panel later, Autrey led off with a single through the left side of infield and he later moved to second on V.J. Bunner's groundout before hustling around to score on an infield single by Aaron Olivas with two outs.
The Cardinals' fifth run came in the fifth on Johnson's run-scoring single.
The Roadrunners (21-31, 10-20 SLC) took advantage of three Lamar errors in the bottom half of the frame to plate a pair of runs.
Junior Daniel Rockett started the inning by reaching on an error. Three pitches later, he stole second base and moved on to third as the throw from Thomas Henk skipped into center field. Sophomore RJ Perucki then followed with an RBI single to right and after senior Jason Mohn singled to right, senior Colby Braddock hit a grounder that was thrown away and that allowed Perucki to score.
However, the Cardinals answered with a four-spot in the sixth, highlighted by Jeff Abt's two-run shot to left-center field.
UTSA managed a pair of runs in the bottom of the panel, as junior Ryan Dalton belted a two-run round-tripper.
Both teams went scoreless in the final three stanzas, but the Roadrunners loaded the bases in the ninth and brought the tying run to the on-deck circle before Lamar closed out the game.
Senior Casey Selsor (4-8) surrendered nine runs on 11 hits and struck out six in his 5.2 innings.
The series continues at 6 p.m. on Friday.
