And, as was the case in the previous two games, Tech came out on top, winning 10-9 on Wednesday.
Tech catcher Willie Durazo went 2-for-4 with three RBIs, while Bryon Smith and Gera Alvarez each knocked in a pair for Tech.
Dusty Buck picked up his first win of the season, allowing just two runs on three hits with three walks and three strikeouts in five innings. J.J. Newman got the save despite allowing two runs on a homer in the bottom of the eighth.
TCU drops to 3-6 on the year, with four of those losses coming against Tech. The Horned Frogs, as in Tuesday's 14-13 Tech win, overcame a huge deficit to close to within one, but came no closer.
Tim Collinsworth took the loss, allowing six runs on seven hits and three walks while striking out four in 3 2/3 innings work.
The Raiders (10-4) jumped out to a 10-1 lead through 5 1/2 innings before TCU started chipping away. TCU cut it to 10-4 on Will Lewis' two-run single and an RBI infield hit by Levin Robinson.
The big blow came in the eighth when Lewis ripped a three-run homer to left off Tech reliever J.D. Seger. Newman came in and got two quick outs before giving up a single and a two-run homer to left by Mike Settle, pulling the Frogs within a run.
Newman, however, rallied to get the final out of the inning, then retired the Horned Frogs in order in the ninth, which included back-to-back strikeouts.
Alvarez finished 2-for-3 with two RBIs and three runs scored, while Smith went 2-for-4.
Joel Buchenauer also had a two-hit game with an RBI, while Nick Blankenship ripped hit sixth homer of the season, a solo shot to left in the second.
