Diamondbacks to designate struggling catcher for assignment

The Diamondbacks are designating catcher Tucker Barnhart for assignment, according to Nick Piecoro of the Arizona Republic. Piecoro indicates that the move will clear space on the club’s roster for Gabriel Moreno to be activated from the injured list prior to the club’s next game against the Dodgers on Tuesday.

Barnhart, 33, made Arizona’s Opening Day roster as the primary backup to Moreno over Jose Herrera. The veteran has struggled mightily this year, however, slashing just .165/.283/.190 in 94 trips to the plate with the Snakes this season. That line includes a surprisingly strong 13.8% walk rate, but those decent on-base skills are outweighed by his massive 33% strikeout rate and complete lack of power (as evidenced by an ISO of just .025). When Moreno went on the IL with a sprained thumb, Herrera was called up to the big leagues to join Barnhart in the catching tandem, and evidently the club has decided that they’d prefer to leave the 27-year-old in the backup role once Moreno returns from the injured list on Tuesday.

The veteran backstop has struggled to be productive at the plate throughout the majority of his career, as evidenced by a career 78 wRC+ and a 68 wRC+ over the past five seasons. Barnhart has generally made up for that lack of offensive production with a strong glove behind the plate, even winning two Gold Glove awards during his tenure with the Reds. That aspect of his game has dried up in recent years, however. After regressing defensively during his time with the Cubs last year, Barnhart was below average by all three of Statcast’s defensive metrics for catchers: Blocks Above Average, CS Above Average, and Framing. Given that reality, it’s easy to see why Arizona would turn to Herrera, who is similarly limited on offense but appears to be a superior defender as compared to Barnhart at this stage of his career.

Taking Barnhart’s place on the roster will be Moreno, who last suited up for the Dbacks on June 21 and has been nursing a thumb sprain since then. The 24-year-old youngster is in his second season with Arizona after coming over alongside Lourdes Gurriel Jr. in the Daulton Varsho trade during the 2022-23 offseason. Moreno has performed solidly behind the plate in 172 games with the Diamondbacks, slashing .265/.330/.385 with a roughly league average 97 wRC+ and strong grades for his defense at catcher.

Once Barnhart’s DFA becomes official, the Diamondbacks will have seven days to either work out a trade involving the veteran or attempt to pass him through waivers. If he goes unclaimed on waivers, Arizona could attempt to outright him to the minor leagues as a non-roster depth option, but the 11-year MLB veteran has more than enough service time to reject such an assignment and test free agency.
