Following a bonus-skimming scandal in 2008, the White Sox' international operations essentially ground to a halt until they signed Adolfo for $1.6 million out of the Dominican Republic five years later. MLB Pipeline's No. 2-rated international prospect that summer behind Eloy Jimenez, he has boasted one of the highest ceilings in the system since turning pro -- but also has had great difficulty staying healthy. Ankle and hamate injuries shortened his first two seasons, Tommy John surgery cost him the last two months of 2018, and follow-up arthroscopic surgery on his elbow limited him to 36 games in 2019.
Adolfo generates well above-average raw power with bat speed, strength and the loft and leverage in his right-handed swing. He made encouraging progress at recognizing pitches and using the whole field in 2017-18, but he was overly aggressive and pull-happy in his brief action last season. He struck out in 39 percent of his plate appearances between the Minors and the Arizona Fall League, and there's concern as to whether he can make enough contact to fully tap into his prodigious pop.
Adolfo had one of the strongest outfield arms in the Minors before he had his elbow reconstructed, and it should continue to deter baserunners now that he's fully healthy again. He moves well for his size, displaying average speed and defensive ability in right field. If he can stay on the field and make some progress at the plate, he eventually could become part of a slugging White Sox outfield with Jimenez and Luis Robert.

After a bonus-skimming scandal in 2008 essentially shut down the White Sox international operations for a few years, they got back in business by signing Adolfo for $1.6 million out of the Dominican Republic in 2013. MLB Pipeline's No. 2-rated international prospect that summer behind current organization mate Eloy Jimenez, he has seen his progress slowed by injuries. Ankle and hamate issues truncated his first two full pro seasons, he missed the last two months of 2018 following Tommy John surgery and played just 36 games this season because of arthroscopic elbow surgery.
When healthy, Adolfo has made encouraging progress at the plate during the last two seasons. He's showing more patience and making more consistent contact, allowing him to make better use of his well above-average raw power. He's recognizing pitches better, using the entire field and understanding that home runs will come naturally thanks to his bat speed, strength, loft and leverage in his right-handed stroke.
Adolfo has the best outfield arm in the organization and had one of the best in the Minors before he got hurt, and it should bounce back after his elbow reconstruction. He moves well for his size and projects as an average runner and defender in right field. He has one of the highest ceilings in the system, though his chances of reaching it won't be clear until he can stay on the field for a longer stretch of time.

A bonus-skimming scandal in 2008 destroyed the White Sox international scouting department, which didn't make a significant signing for another five years. That drought ended with Adolfo, who signed for $1.6 million out of the Dominican Republic as MLB Pipeline's No. 2-rated prospect in the 2013-14 international crop (behind only current organizationmate Eloy Jimenez). Ankle and hamate injuries ruined his first two full years as a pro before he ranked fifth in the low Class A South Atlantic League with 16 homers in 2017 -- though that season ended two weeks early when he punched a dugout door in frustration and broke his left pinky.
Adolfo has two exceptional tools in his raw power and his arm. His combination of bat speed, strength and loft and leverage in his right-handed swing gives him massive pop to all fields. He still needs to make more consistent contact, though he improved last year when he started to recognize pitches better and became less pull-conscious.
Adolfo has the best arm strength among Chicago's position prospects, further enhancing his right-field profile. He has average speed and should be an average defender on an outfield corner. He was diagnosed with a torn flexor muscle and a strained ulnar collateral ligament in his elbow during Spring Training, then played well with the injury until the White Sox shut him down in July so he could get Tommy John surgery in time to be ready for 2019.

After a bonus-skimming scandal rocked the White Sox' international scouting department in 2008, it didn't make a significant signing for five years. That drought ended when Chicago signed Adolfo, MLBPipeline.com's No. 2-rated prospect in the 2013-14 international signing period, for $1.6 million out of the Dominican Republic. Ankle and hamate maladies limited him to a total of 91 games in his first two full pro seasons, but he finally started to hit as hoped when he stayed healthy in 2017.
Adolfo combines bat speed and strength with loft and leverage in his right-handed swing, giving him as much raw power as any White Sox prospect. He hit just .225/.283/.356 with a 36 percent strikeout rate in his first three years a pro, when his stroke often got too long and too steep. Getting regular at-bats has helped him make adjustments this year, as he has started to recognize pitches better and become less pull-happy.
Adolfo's arm strength is just as jaw-dropping as his power, and those two tools make him an easy fit for the right-field profile. He's already starting to mature and could lose a step off his presently average speed once that process is complete. That shouldn't stop him from becoming an average defender, however.

A bonus-skimming scandal destroyed the White Sox international operations in 2008, and it took them five years to start rebuilding it again. Their first big move was signing Adolfo, MLBPipeline.com's No. 2-ranked prospect for the 2013-14 international signing period, for $1.6 million. He spent his first two years as a pro in Rookie ball, struggling as a 17-year-old in 2014 and playing just 22 games last year before needing surgery to repair a fracture and ligament damage in his left ankle.
Adolfo has as much raw power as anyone in Chicago's system, generating it with a combination of bat speed, strength, leverage and loft in his right-handed swing. He also has holes in his stroke, which can get long and feature an extreme uppercut, and his pitch recognition is only rudimentary. He'll need time to develop as a hitter, and he has it on his side because he'll be 19 throughout the 2016 season.
Adolfo's arm strength is just as impressive as his power potential, making him an easy fit in right field. He has seen some action in center field but likely will lose a step off his presently solid speed once he fills out and will be better suited for a corner.

The White Sox have been rebuilding their Latin American program since a bonus-skimming scandal ruined it in 2008, and their biggest move since then came in July 2013. Chicago landed Adolfo, MLBPipeline.com's No. 2-ranked international prospect, for $1.6 million. He's still just 18, and scouts inside and outside the organization speculate that he could have been the No. 1 overall pick in the 2015 Draft if he were a U.S. high school senior.
Adolfo has immense power potential that results from bat speed, long levers, good loft in his right-handed swing and projectable strength. He's still learning at the plate, as evidenced by his Rookie-level Arizona League-leading 85 strikeouts in 46 games in his pro debut. He'll need to improve his pitch recognition to fully tap into his all-fields pop.
Adolfo's arm strength is nearly as impressive as his raw power, making him a natural for right field. That's where he played in his debut, though he showed the aptitude for center field during instructional league and will get time more there in 2015. Presently a solid runner, he figures to lose a step once he matures physically.

A bonus-skimming scandal wrecked the White Sox Latin American program in 2008, and the club hired special assistant Marco Paddy three years later to turn the program around. Paddy's biggest move yet came last July when he signed Zapata, MLBPipeline.com's No. 2-ranked international prospect, for $1.6 million.
Zapata could have more raw power than any prospect on the international market last year. He has a very quick bat, long levers, loft in his swing and a very projectable 6-foot-3 frame. Zapata is still somewhat raw at the plate -- understandable, considering that he's just 17 -- and will have to improve his pitch recognition.
Zapata runs well for his size, though he figures to lose a step as he fills out. With his strong arm, he figures to end up in right field.
