Lidia Gomez Carrera grew up playing junior tennis in her native Spain, but the senior international student at Maine Central Institute knew little of the other three semifinalists who gathered at Bates College in Lewiston on Monday to crown the state’s 2022 Maine Principals’ Association girls’ singles titlist. So Gomez studied her opponents as she began to play them, then used her blend of power, placement and patience to make any necessary adjustments while winning two straight-set matches to become MCI’s first state champion in the sport. The top-seeded Gomez, who couldn’t play at states during her first year at MCI last spring due to COVID-related travel and quarantine issues as she returned to the Pittsfield campus from a spring trip home, capped off her second straight undefeated season of interscholastic tennis in Maine with a 6-4, 6-3 victory over sophomore Coco Meserve of Brunswick in the title match. “I am proud of myself,” said the 17-year-old Gomez, who hails from Caceres, a city of nearly 100,000 residents in west-central Spain.
