Padres sign 29 players after the 2026 MLB amateur draft

The San Diego Padres used the first major transaction window after the 2026 MLB amateur draft to build depth throughout their player development pipeline, signing 29 players in total, including 20 of 21 draftees and nine undrafted free agents. The haul reflects a typical offseason posture for organizations that prioritize stocking multiple paths to the big leagues rather than focusing solely on the top pick.

San Diego’s early draft success was led by right-hander Coleman Borthwick, the club’s top selection. Borthwick, an 18-year-old high school pitcher listed at 6-foot-6 and 255 pounds, was described as the top right-handed high school pitcher available in the draft. According to Yahoo Sports’ report, his fastball has already reached 100 mph, giving him immediate arm strength and velocity that scouts generally associate with upside at higher levels.

Pitching is often the most expensive profile to develop, and the Padres’ emphasis on Borthwick fits that reality. The reporting also emphasized that Borthwick has a quality slider, an essential secondary offering for young starters trying to translate raw power into strike-throwing and pitch sequencing. The article further notes that he has toyed with a changeup, though it has not been a necessary weapon at the high school level, which is a common development step for hard-throwing arms as they progress through pro hitters.

Beyond the headliner, the Padres’ signing number provides a snapshot of how draft day outcomes translate into organizational control. Signing 20 of 21 drafted players suggests the Padres were largely able to close the gap between prospect expectations and contract negotiations, leaving just one draftee unsigned from that class as of the time of the report. The addition of nine undrafted free agents also indicates San Diego found multiple opportunities beyond the 21 players selected on draft day, which teams often do by targeting college arms, spring standouts, and late-blooming high school performers not fully accounted for on draft boards.

For organizations, undrafted signings serve a different purpose than top-round selections. Draft picks can carry structured expectations based on slot value and perceived ceiling, while undrafted free agents are frequently viewed as depth with possible surprise development. In practice, that means they can still become useful pieces, particularly as organizations look to fill out minor-league rotations, bullpen roles, and position-player benches to manage player workload and progression.

What to watch next is how quickly this group starts to move through San Diego’s internal evaluation process. The Padres will typically assign newly signed players to minor-league instruction and early-season development plans, where the first priorities are health, mechanics, and learning how their tools perform against more advanced competition. With a pitcher like Borthwick, the organization’s next milestones will likely revolve around refining the slider’s consistency and determining how the changeup develops as a third option rather than an occasional look.

The broader takeaway is that San Diego has begun the pro cycle with a substantial influx of talent, 29 total signings, which can help stabilize depth across multiple age groups in the system. Even if not every signee reaches the majors, the cumulative effect is meaningful: more arms and more position players create competition, reduce bottlenecks, and give the organization options when injuries or performance changes occur at each minor-league level.
