Gregory Santos

Performance Analysis

Gregory Santos currently profiles as a middling depth reliever on a Giants staff that has been cycling through roster moves at a notable clip in the early weeks of the 2026 regular season. His C-grade performance reflects a player who occupies the margins of a big-league roster rather than a trusted high-leverage role — functional, but not a stabilizing force in the bullpen. The clearest validation of his ability comes from his sustained success at Triple-A Sacramento, where repeated hot stretches have been the direct catalyst for each of his call-ups; that minor-league production is the strongest evidence in his favor. The persistent pattern of options and recalls, however, is the defining weakness in his profile — a player who commands genuine big-league confidence doesn't require this volume of roster shuffling to stay on the active squad. His rookie scale contract keeps him cost-controlled and roster-flexible, which explains why the Giants continue to invest in his development despite the lack of a permanent foothold at the MLB level. The sentiment narrative around Santos remains muted, steady at a D grade over the last 30 days, driven almost entirely by transactional headlines rather than performance moments that build broader fan investment. With the regular season still in its early stretch, Santos is a legitimate watch-list arm — the kind of pitcher whose 2026 story could read very differently in August depending on whether he finally converts sustained opportunity into a cemented role.
