Chatham was an outfielder who flashed a mid-90s fastball as a reliever at American Heritage High (Plantation, Fla.), which has produced four big leaguers and five first-round picks, including 2018 Red Sox choice Triston Casas. Chatham went to Florida Atlantic, where he moved to shortstop and blossomed into the highest pick in school history (51st overall) as well as the Conference USA player and defensive player of the year in 2016. Persistent hamstring injuries limited him to seven games during his first full pro season, but he stayed healthy in 2018 and finished second in the Class A Advanced Carolina League batting race at .315.
Chatham's most valuable attribute is his ability to make consistent line-drive contact. He hinted at average raw power as an amateur that has yet to translate to home run production as a pro, though Boston hopes he can unlock more pop if he adds some strength to his lanky frame and some loft to his relatively flat right-handed swing. He has average speed and is effective on the bases, albeit not much of a threat to steal.
His instincts and quick first step allow Chatham to cover ground and get the job done at shortstop. He still has a strong arm and soft hands, and he should be able to play second or third base if needed. He has one of the higher floors among Red Sox position prospects and a decent upside as a reliable if unspectacular regular.
