De Los Santos has been mediocre in 123 games at Double-A (.253/.300/.426) while being extremely young for the level. The power-hitting corner infielder generates impressive exit velocities and hit 20 homers in 113 games last season, but his 0.20 BB/K portends significant struggles at the highest level. His readiness will be tested after Cleveland selected him in the Rule 5 draft and stole him from Arizona, at least for now. If he does not look capable in spring training of providing any value at the big-league level, the Guardians would likely return him to Arizona, but they may be able to find a short-side platoon role for De Los Santos in 2024, and if they keep him on the active roster all season they can send him back to the minors in 2025. In addition to an over-aggressive approach, De Los Santos has been a notoriously poor defender to date, which is partly why Arizona didn't protect him from the Rule 5 draft. He doesn't turn 21 until June and would likely be limited to designated hitter and some first base work if he spends the year on Cleveland's active roster. Read Past Outlooks
