Chatham was an outfielder who flashed a mid-90s fastball as a reliever at American Heritage High (Plantation, Fla.), a program that has spawned four big leaguers and five first-round choices, including 2018 Red Sox pick Triston Casas. Chatham moved to shortstop at Florida Atlantic and became the highest pick in school history, signing for $1.1 million as a second-rounder in 2016. Hamstring injuries limited him to seven games in his first full pro season and cost him three weeks in 2019, when he posted a career-high .741 OPS and reached Triple-A.
A career .298 hitter in his first four pro seasons, Chatham has an extremely contact-oriented approach. He sprays line drives to all fields with a flat right-handed swing, rarely driving the ball in the air and putting the bat on the ball so easily that he doesn't walk much. Most of his offensive value will come from his batting average.
An average runner, Chatham covers ground at shortstop with a quick first step and good instincts. His strong arm and reliable hands also fit at short and allow him to play anywhere in the infield. He has a higher floor than most Boston prospects but projects more as a utility man unless he develops some more pop or on-base ability.

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.

Chatham led Florida Atlantic to its first-ever Conference USA regular-season title in 2016, winning accolades as the league's player and defensive player of the year while playing through a broken hamate in his right hand. The Red Sox made him the highest pick in Owls history, signing him for $1.1 million as the 51st overall choice, but haven't gotten to see much of him yet. The hamate injury hampered him during his pro debut, while repeated hamstring issues limited him to just seven games in 2017.
Though he's just an average runner and taller than most shortstops at 6-foot-4, Chatham shouldn't have to move from shortstop. His instincts and quick first step improve his range, and his strong, accurate arm allows him to make all of the throws. If he winds up shifting to second base, he still should provide enough offense to profile as an everyday player.
Chatham has a track record of making consistent line-drive contract from the right side of the plate, though he could use some more patience to draw more walks. His size gives him good leverage and more raw power than most shortstops, and he could produce 30 doubles and 12-15 homers annually. He won't steal many bases but is an effective runner.
Despite playing with a right hand injury eventually diagnosed as a broken hamate bone, Chatham led Florida Atlantic to its first-ever Conference USA regular-season title in 2016, earning league player-of-the-year and defensive-player-of-the-year recognition along the way. The first college shortstop drafted in 2016 and the highest pick in school history, he went 51st overall and signed for $1.1 million. His hamate injury hampered him early in his debut but he hit .320 with four homers in his final two weeks, and then he missed most of the first three months of the 2017 season with repeated hamstring issues.
Taller than most shortstops at 6-foot-4 and possessing just average speed, Chatham nevertheless should be able to stick at the position. His quick first step and his instincts enhance his range, and he has the strong, accurate arm to make any throw necessary. If he does have to move, he has enough bat to still profile as a regular at second base.
Chatham has a track record of making consistent contact and could produce solid batting averages if he improves his patience at the plate. He has more raw power than the typical shortstop, thanks to the leverage in his right-handed swing, and should be good for double-digit home runs and plenty of doubles on an annual basis. He's not a threat to steal but runs the bases well.
