The Marlins have placed infielder Isan Diaz on the 60-day injured list due to a left groin strain, according to multiple reporters (including MLB.com’s Joe Frisaro). Infielder Sean Rodriguez has been activated from the injured list to take Diaz’s spot on the active roster.
The IL placement will officially end a very unusual season for Diaz, who ended up appearing in seven games and hitting .182/.182/.182 over 22 plate appearances. Diaz played in two games before deciding to opt out of the 2020 season, and then opted to rejoin the Marlins in September after getting permission from both the league and the MLBPA. All things considered, 2020 is essentially a lost year for the top prospect, though one would think he still projects as a big part of Miami’s future plans.
Diaz had been starting regularly at second base since his return, but the keystone may now be handled by a combination of rookie Jazz Chisholm and Rodriguez, who now seems set to officially begin his Marlins tenure. Rodriguez signed a minor league deal with the Fish prior to the season and made the Opening Day roster, but was placed on the IL along with a dozen teammates in early August. While no official reason was given for Rodriguez’s absence, it is probably safe to assume that it was COVID-related, given the outbreak that hit Miami’s roster around that time.
The 35-year-old Rodriguez is a veteran of 12 MLB seasons, with a .226/.302/.380 slash line over an even 2900 plate appearances. Rodriguez has played all over the field during his career, giving the Marlins a pair of versatile utility pieces in Rodriguez and Jon Berti, once Berti (finger laceration) returns from what is expected to be a minimal injured list stint.
