The left-handed Padres prospect allowed two hits over eight scoreless innings, striking out nine as the Class A Advanced Storm beat the Rancho Cucamonga Quakes, 1-0, to advance to the California League Championship Series for the sixth time in franchise history.
The game marked the third time the Quakes had been shut out in their last 144 games. Rancho Cucamonga led the league with 848 runs scored this season.
Schmidt (1-0) did not allow a hit until the top of the fifth, when Blake Smith led off the inning with a double to center field. The only other base knock off the 25-year-old came in the seventh when Angelo Songco singled on a drag bunt to second base.
Jeff Ibarra tossed the final frame for Lake Elsinore, setting down three in a row to notch his first save of the postseason.
Jake Blackwood drove in the only run of the game, plating Nathan Freiman with a two-out single in the fourth.
Selected with the 23rd overall pick in 2007, Schmidt went 3-5 with a 3.84 ERA in 12 California League starts during the regular season. He allowed one run over seven innings in the Storm's playoff opener against the Inland Empire 66ers, but did not factor into the decision. His postseason ERA stands at 0.60 in 15 innings.
The best-of-5 Championship Series starts Thursday, with the Storm facing off against the Stockton Ports. Lake Elsinore will host Game 1.
