Major League Baseball’s international signing period opens today for the 2026 class, which means prospects can officially sign their contracts.

For Baseball America subscribers, we have full breakdowns of the signing classes for all 30 teams, including scouting reports on the top players for each organization, other big names to know and lower-profile players to watch who could be sleepers.

The Pirates had one of the breakout prospects of the 2025 minor league season with outfielder Edward Florentino, a player they originally signed out of the Dominican Republic two years ago for $395,000. This year, a pair of shortstops from the Dominican Republic will be two of the headliners of Pittsburgh’s 2026 international signing class.

Dominican shortstop Wilton Guerrero Jr. is the latest member of the Guerrero family to join a major league club, signing with the Pirates for $1.9 million. Wilton Guerrero—the brother of Vladimir Guerrero Sr. and uncle of Vlad Jr.—was primarily an infielder during his big league career from 1996 to 2004 with the Dodgers, Expos, Reds and Royals. Wilton Guerrero Jr. is built like his father, a small-to-medium frame (5-foot-10, 165 pounds) packed with quick-twitch athleticism. He’s a plus-plus runner with hand-eye coordination that’s evident at the plate and in the field. He ranges well at shortstop, where he has good instincts and a strong arm to project to stick at the position. On the younger end of the class, Guerrero will need to get stronger to drive the ball with more impact, but the bat speed for his size is solid and he makes contact at a high clip, with a high baseball IQ that’s no surprise given his upbringing.

Dominican outfielder Jeancer Custodio ($900,000) as a 15-year-old played in the U-18 World Cup Americas Qualifier in 2024 in Panama, batting .333/.429/.375 to rank second on the Dominican team in OPS among qualified hitters behind current Giants shortstop Josuar Gonzalez. Custodio is strong for his age and projects to have a burly build. He has the strength to drive the ball out of the park to his pull side and could grow into 20-plus home run power. Scouts highest on Custodio liked his hand-eye coordination to be able to tap into his power in games, though there was a split camp about how his swing and pure hitting ability would translate at higher levels. Custodio is an above-average runner underway, so he could see time in center field at the lower levels, but he’s built more like a corner outfielder and probably will shift there long term.

An up-arrow prospect for 2026, Dominican shortstop Alexander Pio is 6-foot-3, 200 pounds, a physical, righthanded-hitting shortstop along the lines of Juan Sanchez, Toronto’s top player from the 2025 international class. He’s strong for a 16-year-old, can drive balls with impact and shows the potential to be a 20-plus home run threat. Pio could end up outgrowing shortstop and he has a strong arm that would fit well at third base, but he’s a good athlete for his size and a plus runner, so he should get the opportunity to develop at shortstop.

Angel Nieto is a catcher from Panama with a lot of organized game experience that shows in his high baseball IQ. He projects to stick behind the plate with advanced catch-and-throw skills for his age and a strong arm, along with a solid righthanded bat for a catcher with a line-drive approach and gap power. 

Venezuelan outfielder Juan Figueroa is another savvy player as the son of a scout. He’s 6-foot-2, 170 pounds, a lean, flexible build with significant physical upside remaining to grow his gap power. He’s a good athlete with above-average speed in center field. 

Righthander Neomar Urbina stands out for his present stuff and physical projection for more in the tank. He’s already up to 94 mph with considerable room on his 6-foot-4, 190-pound frame to fill out and eventually grow into upper-90s velocity. Urbina throws a slider and changeup as well, but it’s the potential for an upper-tank fastball that jumps out the most.

Mingxuan Zhang is a 6-foot-7, 220-pound righthander from China. He has pitched at the MLB Development Center in China as well as in the United States. His fastball gets into the low-90s from a difficult angle with the size and arm speed to project more to come, along with a high-spin slider that could become his best pitch.

Dominican outfielder Carlos Tejera was eligible to sign last year but is signing in 2026. He’s an athletic 6-foot-2, 190 pounds with plus speed, an average arm and hard contact from the left side of the plate.
