Since opening in 2022, Maven has assessed thousands of baseball players with force plates that use sensors to measure the amount of energy being transferred into the ground during a swing. Griffin was the top-ranked 16-year-old in the country, a 6-foot-4, 200-pound specimen, and the plate was no match for him. Though the plate was anchored into a portable frame that had withstood swings from perennial major league All-Stars and MVP-caliber players, the force Griffin was creating jarred it loose.
Griffin has taken off like a meteor this season and his penchant for impact hasn't slowed down even despite a promotion to High-A. The 19-year-old has made significant strides in allaying concerns about his hit tool and approach, and the rest of his overall game has evaluators buzzing as they envision how his plus power, speed and at least above-average defense at two different positions could come together.
