NL West Notes: Rodriguez, Thomas, Musgrove, Montgomery

The Diamondbacks sent both left-hander Eduardo Rodriguez and outfielder Alek Thomas for MRI exams last week, and Torey Lovullo told reporters (per MLB.com’s Injury Tracker) that the results of Rodriguez’s MRI were “very positive,” but that there was no update on Thomas’s status as the club plans to seek second and third opinions on the youngster’s results.

It’s excellent news for the Diamondbacks that Rodriguez is making his way toward a return, with Lovullo indicating that he’s set to begin a throwing program. Rodriguez will be sidelined through at least May 24 due to his placement on the 60-day injured list but it’s at least feasible he could return to game action not long after that if he manages to avoid further setbacks. Rodriguez’s lat injury woes have prevented him from making his Dbacks debut to this point in the 2024 campaign, but he’s coming off an excellent season with the Tigers last year that saw him post a 3.30 ERA and 3.66 FIP in 152 2/3 innings of work and should provide a major boost to an Arizona rotation that’s currently relying on Ryne Nelson and Slade Cecconi in the absence of Rodriguez and veteran righty Merrill Kelly.

As for Thomas, the lack of update from the Diamondbacks is a somewhat ominous sign regarding his hamstring. The 24-year-old was initially scheduled to be activated from the IL last week but ended up exiting a rehab outing with Triple-A due to an issue with his injured hamstring on May 5 that ultimately did not improve after a day off, prompting Arizona to delay his return and send him for testing. Once a consensus top-30 prospect in the sport, Thomas has struggled at the big league level with a .230/.273/.362 slash line in 242 career games but nonetheless figured to be the club’s starting center fielder this season. Corbin Carroll has handled center field in Thomas’s absence with Jake McCarthy stepping from the bench into Thomas’s spot in the lineup while manning right field.

• Padres right-hander Joe Musgrove is making good progress in his return from right elbow inflammation, according to manager Mike Shildt (per MLB.com’s Injury Tracker). The 31-year-old’s initial worrisome diagnosis was described as “precautionary” when he was initially placed on the shelf last week, and it appears that description was an apt one as Musgrove has reportedly already begun light baseball activities, including playing catch. MLB.com writes that the right-hander is optimistic that he’ll be able to return “shortly after” the minimum 15-day stint on the IL, which would likely result in him returning to action sometime next week. San Diego is surely hoping that Musgrove will look more like the ace hurler who posted a 3.05 ERA in 459 2/3 innings in a Padres uniform entering the 2024 campaign than he has to this point in the season, as he struggled badly with a 6.37 ERA and 5.96 FIP in eight starts prior to his placement on the shelf.
• The Rockies may have lost outfield prospect Benny Montgomery for the season on Friday, as MLB.com’s Thomas Harding relays that the 21-year-old underwent shoulder surgery that Rockies director of player development Chris Forbes said will keep him out until at least “toward the end of the year” if he’s able to return this season at all. The club’s first-round pick in the 2021 draft, Montgomery turned heads during the Arizona Fall League last year with a .333/.436/.500 slash line in 19 games and was hitting a solid .283/.313/.500 in his first taste of Double-A action before being sidelined by the shoulder injury.
