One potential prospect callup for each team 2026

MLB.com analyst Jonathan Mayo has identified one prospect callup candidate for each of the 30 MLB teams for the remainder of the 2026 season, noting that 14 of the featured prospects appear on the Top 100 Prospects list. The article was prompted by Cardinals prospect Joshua Báez's historic debut last Saturday, in which he became the first player in Major League history to homer in his first three plate appearances. Players called up from this point forward will retain rookie eligibility for 2027, meaning a strong performance could earn their team a Priority Pick in the 2028 draft.
