South County softball stands undefeated through six games, and the reason for the team’s success is no secret.

“Our pitching has been outstanding, and most of that has been Cara Martin,” South County Coach Gary Dillow said. “She’s been almost unhittable.”

As a freshman last season, Martin established herself as a dominant force in the circle, recording a 1.32 ERA and 222 strikeouts in 127 innings. After the Stallions’ run to the Virginia Class 6 state quarterfinals, Martin was named to the Virginia Class 6 all-state second team, the lone freshman to earn all-state honors.

A debut like that sets a high bar for an encore, but Martin is exceeding expectations for No. 5 South County.

She tossed six shutouts in 20 starts last season. She has nearly matched that already, with five shutouts in her five starts as a sophomore.

In back-to-back starts against Patriot District rivals Wednesday and Thursday, she struck out 33 batters — 17 in a 4-0 win against West Springfield and then 16 in a 1-0 win against Robinson the next day.

The scary part for opposing hitters? She could get even better.

Martin consistently throws in the low- to mid-60s, according to Dillow, already an impressive accomplishment for a high school pitcher. To take her game to the next level, she is developing a change-up to throw batters off the scent of her faster pitches.

“If she can add that, she’ll be devastating,” Dillow said.
