Rocha threw a complete-game shutout and allowed five hits to earn his third victory and improve the Sooners to 11-0.
Although the shutout was impressive, Rocha has been dominant on the mound in all three of his starts. He has allowed just two runs, both in his second start, in 23 innings and boasts a 0.78 ERA.
But Rocha wasn't the only starting pitcher who had a good outing. Both pitchers had quality starts, but San Diego State pitcher Steven Moranda was the first, and only, pitcher to make a mistake.
Junior first baseman Cameron Seitzer plated the first run in the fourth inning on a hard single past a diving third baseman, but Moranda regained his composure and kept OU's bats silent until the eighth inning.
The Sooners tacked on two more runs in the eighth to start to give Rocha some insurance runs.
Seitzer doubled and scored a batter later when a single by junior catcher Tyler Ogle was mishandled by the centerfielder. The lanky first baseman advanced home on the error.
Seitzer collected two hits in four at-bats in a game where his father Kevin Seitzer was in attendance. Many players get the chance to play in front of their parents all year, but the elder Seitzer can't be at many games because of his job as the Kansas City Royals' hitting coach.
Junior right fielder Cody Reine kept the inning going with an RBI triple to right-center.
The Sooners added a run in the ninth inning when senior shortstop Cale Ellis scored on a throwing error, and Rocha recorded a scoreless bottom of the ninth to close the game.
OU will be attempting to tie a program-best 12-0 start tomorrow at 3 p.m. CT—the only other time it did so was back in 1998—and senior pitcher Bobby Shore will be on the mound looking for his second win of the season.
