Matt Purke and Tyler Lockwood held UCLA to four hits and Taylor Featherston hit the biggest of TCU's three home runs, leading the Horned Frogs to a 6-2 win Friday that keeps them alive in the College World Series.
TCU (54-13) forced a second Bracket 1 title game on Saturday with the winner going to the best-of-three finals beginning Monday.
Featherston's two-run homer off reliever Garett Claypool gave TCU a three-run lead in the bottom of the seventh after the Bruins (50-15) had closed to 3-2.
The unbeaten Purke set a school record with his 16th win of the season and Lockwood earned his eighth save. UCLA starter Rob Rasmussen (11-3) struggled with his control early and left in the fifth inning.
