The first opportunity for the Padres to restock the system arrived Wednesday.

The Padres wasted little time, signing three players from Baseball America’s top-100 prospects list as the international amateur window opened.

Cuban shortstop Joniel Hernandez topped the day’s activity, signing for $1.4 million, according to Baseball America, of the Padres’ $5.94 million bonus pool. Mexican left-hander Diego Serna signed for $1 million, while Curacao shortstop Timothy Mogen also signed for a yet-to-be reported amount.

Hernandez (No. 31), Serna (No. 45) and Mogen (No. 76) are all ranked in Baseball America’s top-100 international prospects list.

Baseball America has also reported the Padres have agreed to deals with Venezuelan right-hander Joel Duarte, Venezuelan catcher Jhoneiker Leon and Cuban right-hander Jordan Pérez. The team has not confirmed those agreements.

Here is Baseball America’s scouting report for Hernandez:

“Hernandez is a quick-twitch, bursty athlete. He has a lean, wiry frame with the projection to get stronger while staying athletic. He’s a plus runner with an above-average arm. Those tools give him a chance to stay at shortstop if his hands and defensive instincts improve, though his speed and athleticism could translate to center field if needed or he could end up moving around the infield and outfield. Hernandez loads with a leg kick and uses quick hands to fire the barrel with good bat speed. He’s still learning to recognize spin and be more consistent with his timing, but when everything is synced up, he can drive the ball with impact. He has projection to grow into above-average power.”

Here is Baseball America’s scouting report for Serna:

“For some scouts, Serna is the top lefthander available in the 2026 international signing class. He has experience pitching for Mexico on the international stage, including in the 2024 U-15 World Cup in Colombia, where he struck out 12 with only one hit and one run allowed over seven innings. Serna combines impressive size, pitchability and stuff with a starter look. He pitches off a fastball that touches 92 mph and should grow into mid 90s or better. Serna complements his fastball with multiple offspeed weapons that he shows feel to manipulate. His best secondary pitch is a slider with two-plane depth into the low 80s that misses bats at a high clip and projects to continue to do so at higher levels. He also shows feel for a changeup with good fading action. Serna’s touch and feel on the mound make him one of the more polished arms in the class.”

Here is Baseball America’s scouting report for Mogen:

“Mogen is one of the top prospects from Curacao for the 2026 international class. He’s 6-foot-4, 170 pounds, an ultra-lean build that lacks strength now but has tons of space remaining to fill out. He’s a quick-twitch athlete with plus speed and a strong arm. He’s still growing into his body and coordination, but he keeps his hands inside the ball well for a longer-limbed righthanded hitter, with a chance for his power and everything else to tick up once he packs on more weight.”
