Giants backup catcher Tom Murphy was diagnosed with a mid-back herniated disc, the team announced to its beat writers this morning (link via Shayna Rubin of the San Francisco Chronicle). He’ll receive an epidural injection and be sidelined for multiple weeks. The Giants haven’t formally ruled Murphy out for Opening Day, but things certainly appear to be trending that direction.
Waiver claim Sam Huff and minor league signee Max Stassi will compete for the backup job behind Patrick Bailey if Murphy is indeed sidelined into the season. The Giants also announced that they’ve pulled catcher Adrian Sugastey from minor league camp and formally given him a non-roster invitation to big league camp, replenishing some of the lost depth.
San Francisco signed Murphy, 34 in April, to a two-year deal worth $8.25MM in the 2023-24 offseason. Though he came to the Giants with notable durability issues, the veteran backstop had a track record of stout production when healthy. From 2019-23 with the Mariners, he turned in a combined .250/.324/.460 batting line in 807 plate appearances — despite playing his home games in perhaps the worst hitters’ environment in the sport. By measure of wRC+, Murphy was 16% better than average at the plate during his run with the M’s.
To this point, Murphy’s contract has played out quite poorly. The righty-hitting veteran appeared in just 13 games early in the 2024 season before suffering a Grade 2 knee strain that was originally expected to shelve him for “at least” six weeks but ultimately proved to be season-ending in nature. Murphy logged only 38 plate appearances in his first year with the Giants and posted an anemic .118/.211/.235 slash.
Though Murphy had a history of injuries, the knee troubles were a new development. He’d previously endured lengthy absences due to a forearm fracture, a foot fracture, a dislocated shoulder and a ligament injury in the thumb on his catching hand. Knee problems were not something he’d battled prior — just as this new development of back woes is not something that’s hampered him in the past.
Last offseason’s addition of Murphy came after years of former No. 2 pick Joey Bart struggling in San Francisco. Murphy’s two-year deal surely played a role in pushing the out-of-options Bart off the roster, and the breakout he enjoyed after being traded to the Pirates only further adds a layer to Murphy’s health troubles. Bart hit .265/.337/.462 in 282 plate appearances with the Bucs last year, hitting his way to the top of the Pirates’ depth chart as we enter the 2025 campaign.
In Huff and Stassi, the Giants have a pair of experienced options to back up Bailey — who’s perhaps the game’s best defensive catcher (and one of the best defensive players in MLB, at any position). Huff just turned 27 and was at one point a top-100 prospect with the Rangers. He owns a solid-looking .255/.313/.455 slash in 214 big league plate appearances, but the Rangers clearly weren’t bullish on his chances of sustaining that production. Given that he’s benefited from a .353 average on balls in play and fanned in more than one-third of his career plate appearances, that’s an understandable concern.
Stassi, 33, hasn’t suited up in the majors since 2022 due to injuries and a harrowing 2023 ordeal wherein his son was born more than three months premature and spent more than six months in the NICU. Thankfully, the end result was Stassi and his wife being able to take their baby boy home, but Stassi’s return to the diamond in 2024 didn’t go as hoped. He’d missed time with a left hip strain early in the 2023 season, and left hip troubles resurfaced in 2024 — this time requiring season-ending hip surgery.
When he’s been on the field, Stassi has been inconsistent but shown signs of being more than a backup. From 2020-21, he slashed .250/.333/.452 with 20 homers in 118 games and 454 plate appearances. He’s an elite pitch framer who’s also shown quality blocking skills on pitches in the dirt. If he’s back to full strength after a grueling couple of years — both personally and professionally — Stassi is an intriguing backup option. He’s need to be added to the 40-man roster, however.
The Giants have a handful of other health issues to keep an eye on in camp, though to this point there doesn’t appear to be major concern on any fronts. Outfielder Heliot Ramos is dealing with an oblique issue, per the Chronicle’s Susan Slusser, but it’s only expected to sideline him for around a week. Ramos is among the most critical young players on the Giants’ roster. The longtime top prospect broke out in 2024, slashing .269/.322/.469 with 22 homers in 518 trips to the plate. The overwhelming majority of his production came against lefties (.370/.439/.750), but if he can improve his .240/.286/.387 output against fellow right-handers, Ramos has massive everyday potential.
Southpaw Erik Miller is also a bit behind, per Slusser. He’s dealing with some numbness in his pitching hand that has naturally led to some concern. He’s not yet undergone extensive testing, so there’s no telling if he’ll miss any time, but the 27-year-old Miller had a breakout of his own during last year’s rookie effort. In 67 1/3 innings out of Bob Melvin’s bullpen, he logged a 3.88 earned run average with a huge 30.6% strikeout rate but also a bloated 13.4% walk rate. He’s currently projected to be the only southpaw in the Giants’ bullpen. They don’t have another left-handed relief candidate on the 40-man roster, although non-roster players like Joey Lucchesi, Enny Romero, Ethan Small and Miguel Del Pozo all have varying levels of MLB experience.
It doesn’t seem as though Harrison will be taking on a full-fledged starter role, as Baggarly notes that Harrison might work in more of a piggyback capacity on Tuesday, perhaps not throwing more than 3-4 innings. Harrison has had a limited workload for much of the minor league season, as he has topped the 80-pitch threshold only three times and has only once thrown as many as five innings in a single outing.
