The Lady Tigers will face Valencia at 4:30 p.m. today for the championship.
Aztec is looking for revenge after losing both games of a doubleheader at Valencia last weekend.
"Valencia is a top-five school in 4A. We knew going into this year they would be a team in the mix at the end of the year. We took a few losses down there but we had seven errors in the first game and six in the second," said Aztec head coach Jose Santistevan. "Defensively, these were the two best games we have had this year. Hopefully we can keep it going."
Valencia advanced to the tournament title after defeating Shiprock 13-0 and Farmington 8-7 in eight innings.
The win for Valencia came a day after the Lady Scorpions secured a 5-4 walk-off win in the seventh inning against the Lady Jaguars.
Pitcher JoJo Curry hit the game-tying home run with two outs in the seventh as the Lady Scorps trailed by two runs, but Valencia's Erin Sharpe hit a walkoff double for the Lady Jaguars in the eighth inning for the win.
"We played one of the best 4A teams in the state down to the wire twice in two days but, out of the 15 innings, we really only played six innings with fire," said FHS head coach Johnny Curry. When we get to where we can play every inning like those six, we will be pretty scary."
Piedra Vista picks up two wins
The Lady Panthers defeated Deming 19-0 in three innings Friday before beating Clovis 7-0 on the first day of the Las Cruces tournament.
Piedra Vista (6-0) saw Jordan Montoya hit her third home run of the year on Friday. Freshman pitcher Megan Risner earned her first win as a Lady Panther inside the circle, giving up two hits and striking out 14 Clovis hitters.
PV will face 5A's top-ranked Carlsbad at noon today.
