Sometimes it only takes one inning to turn a competitive game into a rout, and on Sunday, the San Diego State softball team showed the University of San Diego how true that statement is.

Locked in a scoreless tie, SDSU’s offense exploded for seven runs in the top half of the third inning and defeated crosstown rival USD 7-1.

Junior third baseman Ashley Rose dealt the biggest blow of the inning. With the Aztecs already up 3-0, Rose launched a grand slam over the left field wall to extend SDSU’s lead to seven.

“We got runners on early and got hits at the right time,” freshman utility Hayley Miles said. “We came up in the clutch that inning.”

Head coach Kathy Van Wyk noted that poor Torero defense helped the Aztecs.

“They let us in the game,” Van Wyk said. “They made some errors which kept us alive.”

Not to be overlooked was the pitching performance of senior Samantha Beasley.

She struck out seven Torero batters while giving up only three hits and one run on her way to the complete-game victory.

Junior first baseman Justeen Maeva praised Beasley’s performance after the game.

“She pitched really good today,” Maeva said. “She was very aggressive and came out throwing strikes.”

Van Wyk noted that Beasley’s focus was key coming into Sunday’s game.

“Samantha has been up and down this season,” Van Wyk said. “So we’ve been working on focus issues and the mental games, that really helped her today.”

Miles could tell Beasley’s focus was there from the start.

“She was real focused this game,” Miles said. “I could tell by looking at her pitches out there in center field that she was on her game.”

The 7-1 Aztec victory was the second win against the Toreros this weekend as SDSU swept the two-day series with USD.

On Saturday, the Aztecs took down the Toreros 5-2, as junior pitcher Bailey Micetich had nine strikeouts in six shutout innings.

The Aztecs are back in action as they have a double-header at 1 p.m. today at Cal State Northridge.
