The No. 9 Owls tagged Tech's first four pitchers for 14 of their 17 runs on just nine hits. Most of those came during the third and fourth innings when Rice (2-1) turned a 1-1 game into a 14-1 runaway.
Mike Lorsbach and Jose Enrique Cruz were the sparks for the outburst. Lorsbach's grand slam off Tech reliever J.J. Newman put the Owls up 7-1 after an A.J. Porfirio RBI triple and an RBI groundout by Texas transfer Vincent Sinisi.
One inning later, Eric Arnold's two-run single and Lorsbach's double to right-center put the Owls up 11-1 before Cruz lined a shot over Tech center fielder Tyler Carson's head to straightaway center for an inside-the-park home run and a 13-1 advantage. Justin Ruchti then doubled and scored on Chris Kolkhorst's single to left, making it a 14-1 game.
Houston native Matt Harbin finally ended the bleeding by getting Porfirio to fly to left, but the damage had been done.
Harbin, who lost his starting job with two straight poor outings to open the season, was Tech's best pitcher of the day despite allowing two runs on five hits. He walked none and struck out six in 3 1/3 innings.
That was a far cry from Tech's first four hurlers who combined to last less than four innings. Starter Nathan Fouts (1-1) struggled for the second straight outing, going two innings plus two batters, allowing three runs on two hits with four walks and two strikeouts.
Newman, Justin Cleveland and Matt Lair combined to go just 1 2/3 innings, giving up 11 runs on seven hits and two walks with two strikeouts.
The Raiders' offense, meanwhile, struggled for the third time in as many games. Tech, averaging 10 runs and 12 hits per game going into the tournament, scored just nine runs in going 1-2 in the Classic.
After Rice scored to take a 1-0 lead in the first, Tech answered in the bottom of the frame as Jon Slack singled, went to second on a wild pitch and scored on Scooter Jordan's RBI single up the middle, tying the game at 1-1.
That, however, was all the Raiders would manage as Rice freshman Jeff Niemann (6-foot-9, 260 pounds) allowed just one more hit over the next five innings to pick up his first win.
Tech did touch Niemann for a run in the seventh on a leadoff double by Gera Alvarez and an RBI single by freshman Cody Fuller.
Tech's final two runs came in the bottom of the ninth as Travis McElroy walked and eventually scored on a balk. Brent Fossum, who singled, scored on Jake Valles' double off the left-field wall.
Tech gets a week to regroup before returning to action on Friday at the Southwest Texas State Tournament at Dell Diamond in Round Rock.
The Raiders open the tournament with a 5 p.m. clash against Houston, then will play TCU on Saturday and Southwest Texas on Sunday, both games at noon.
