Giants Sign Miguel Diaz To Minor League Deal

The Giants signed right-hander Miguel Diaz to a minor league contract back in late December, as per Diaz’s MLB.com profile page.  The 30-year-old will presumably also be invited to the Giants’ big league Spring Training camp.

With the exception of the pandemic-shortened 2020 campaign, Diaz has been a part of every MLB season since 2017, ranging from a high of 42 innings with the Padres in 2021 to a lone inning in one game with the Astros last season.  Diaz has a 4.81 ERA, 24% strikeout rate, and 11.7% walk rate over 127 1/3 innings and 88 career big league games with the Padres, Tigers, and Astros, and he has also spent time in the minors with the Brewers and Twins organizations.

Most of Diaz’s better numbers have come more recently in his career, as he has a 2.82 ERA in 60 2/3 innings since the start of the 2021 season.  Despite the strong bottom-line performance, however, some underlying metrics (such as a .222 BABIP) and some inconsistency with his control has kept Diaz from getting much of a look at the big league level.  A 4.93 ERA over 204 2/3 career minor league innings also hasn’t helped Diaz’s case for call-ups to the Show.

Diaz is out of minor league options, which makes it difficult for teams to keep him on the roster without exposing him to waivers.  In 2024, for example, the Tigers lost Diaz on a waiver claim to the Astros in April, and Diaz was then designated for assignment and chose free agency over an outright assignment before quickly re-signing with Houston on another minor league deal.  Diaz was released by the Astros entirely a few weeks later, and he completed the circle by re-signing another minor league contract with Detroit near the end of June.

San Francisco’s bullpen seems largely set, though teams routinely bring multiple veteran pitchers to camp on minors deals just in case of injury, or in case any of these unheralded arms can stand out enough to win a spot on the Opening Day roster.  As noted, Diaz’s lack of minor league options might hurt him in a camp competition, but should he clear waivers and stick around in the organization, he could act as bullpen depth for the Giants during the season.
