The three previous Calipatria hurlers surrendered 11 walks. Peralta came on with one out in the sixth and contained the Scots to preserve the win.
Peralta also was a star at the plate, collecting three of his team's 13 hits. One was a double.
Vontray Taylor provided the biggest spark, though, when he launched a grand slam over the right field fence in Calipatria's six-run first inning. He drove in two more runs in the five-run second with a double.
The tone for the three-hour marathon was set in the first inning. Vincent's Michael Gamboa got aboard on an error and Leonardo Gomez walked. But before the Scots could score, Gamboa was picked off second base and the Hornets turned an unusual double play.
The Scots' Nicholas Santos was at the plate, tried to call time out with two strikes and stepped out of the batter's box. The umpire did not grant the time out and Daniel Sadberry's pitch was called a third strike. Gomez tried to steal second on the pitch but was thrown out.
Calipatria then came to the plate and batted around. With one out Johnny Fallavollita singled to left and Peralta doubled to right field when the fielder lost the ball. Brett Lyerly then was hit by a pitch that bounced first in the dirt in front of him to load the bases.
Ezequiel Navarro followed by reaching base on an error when the left fielder dropped a fly ball. Two runs scored on the play. Then after Sadberry walked to load the bases, Taylor parked his grand slam.
Calipatria batted around again in the second inning, scoring five more runs for an 11-2 lead. Sergio Flores walked, moved to second on a ground out, stole third and scored on an error when the catcher tried to throw him out.
Peralta followed with a walk and Lyerly doubled to push Peralta to third. Peralta scored on a passed ball.
Navarro laid down a bunt single that scored a run and Taylor doubled to right center to drive in the final two runs of the inning.
"It's the same old story," Vincent coach Chava Macias said. "We have two bad innings at the start of every game."
The Hornets scored three more times in the third. Fallavollita singled to center and then got out of a pickle, sliding safely back into first. Peralta singled to right center and Lyerly singled to left to score a run. Hector Maciel lofted a sacrifice to drive in a run and Navarro doubled down the right field line to bring in the last run.
Flores scored for Calipatria in the fourth after singling to left. He moved to second on an error, took third on Peralta's infield single and scored on a passed ball.
Vincent made it interesting with eight runs in the sixth. Santos walked and Chris Del Rio singled to left. Santos then scored on a wild pitch.
Two walks loaded the bases and a third walk scored a run. Donald Schiller then came in and he too walked a batter to force in a run. Two passed balls scored runs, another came home on an error and a fielder's choice helped score a run.
Calipatria added its final run in the sixth off a couple errors. Vincent scored its final run in the seventh thanks to Matt Lankford's base hit and Gamboa's sacrifice fly.
There was even more weirdness. A Vincent player was tossed out of the game for wearing jewelry and another was thrown out for arguing with the umpires.
"That two-week break really hurt us," Macias said, noting Vincent did not play in any tournaments or practice over spring break.
In addition to Peralta and Taylor, Calipatria got two hits from Fallavollita, Lyerly and Navarro and one each from Flores and Daniel Sadberry.
Chris Del Rio had two hits for Vincent and Richie Del Rio, Lankford and Tony Ojeda all had one.
