Dodgers Notes: Yamamoto, Rojas, Graterol, Grove

In his first public comments to reporters since going on the injured list with a rotator cuff strain, right-hander Yoshinobu Yamamoto told reporters (including ESPN’s Alden Gonzalez) yesterday that he’s been playing catch as he works his way back toward the mound. He described pitching again this year as his “goal,” noting that he was trying to return as soon as possible. Though Yamamoto did not specify a specific timetable for his return, Gonzalez noted that the Dodgers are “hoping” their star rookie will be back on the mound for them in late August or early September.

At the time of Yamamoto’s injury, manager Dave Roberts suggested that it wasn’t expected to end his season, so it’s not necessarily a surprise that the 25-year-old hurler still hopes to pitch this year. Even so, any source of optimism regarding Yamamoto’s status is surely a welcome one for fans in L.A. given the number of rotation injuries they’ve suffered in recent weeks. Entering the All-Star break, the club was relying on a patchwork rotation of veteran southpaw James Paxton and rookies Gavin Stone, Landon Knack, and Justin Wrobleski. Although both Tyler Glasnow and Clayton Kershaw are expected to join the mix later this week, providing the club with a solid front four alongside Stone and Paxton, questions will remain about the club’s lacking rotation depth until either Yamamoto or Walker Buehler returns from the injured list, barring a trade in the days leading up to the deadline.

Even setting aside the Dodgers’ current rotation needs, getting Yamamoto back late in the season figures to provide a huge boost to the club as they look ahead towards the postseason. After all, the $325MM righty was generally regarded as the best pitcher available this winter despite his lack of MLB experience, and in 14 starts with the Dodgers prior to hitting the shelf he flashed that potential. In his 76 innings of work this year, Yamamoto sports an excellent 2.92 ERA (137 ERA+) with an even better 2.68 FIP thanks to a fantastic 27.9% strikeout rate against a measly 5.6% walk rate.

While the club received some positive news about Yamamoto this weekend, they also were dealt something of an injury scare today when veteran shortstop Miguel Rojas exited today’s game due to a bout of tightness in his right forearm. Fortunately, Rojas told reporters following the game (including The Athletic’s Fabian Ardaya) that he believes the injury, which he suffered over the All-Star break while doing hitting drills, isn’t a particularly serious one. Roberts echoed that sentiment, noting to reporters (including Ardaya) that the club does not currently plan to send Rojas for an MRI, although he won’t play tomorrow and could ultimately be down for a few days due to the issue.

The loss of Rojas would’ve been a brutal blow for the Dodgers, a somewhat surprisingly reality considering his disappointing 2023 campaign. In 206 trips to the plate for the club this year, Rojas has slashed a respectable .272/.317/.408 that registers as 6% better than league average by wRC+. He’s combined that solid work at the plate with strong defense, initially at second base before sliding over to shortstop to take over for Mookie Betts after he went down with a fractured hand last month. Kiké Hernández took over for Rojas at shortstop after he exited tonight and figures to continuing getting reps at the position in Rojas’s absence, perhaps alongside Gavin Lux.

More positive injury news for Dodgers fans comes out of Triple-A Oklahoma City, where (as noted by OKC Broadcaster Alex Freedman) right-handers Brusdar Graterol and Michael Grove have both been assigned to begin rehab assignments this evening. Each right-hander struck out one while pitching a single inning of work tonight, with Grove working around a walk to produce a scoreless frame while Graterol allowed a hit and an unearned run in his inning of work. That both righties have reached the highest level of the minors in their rehab process is an exciting development for the Dodgers, as it suggests both will soon be available to contribute to a bullpen that has scuffled badly in recent days with a 5.51 ERA and 5.23 FIP since the calendar flipped to July.

Graterol hasn’t appeared in a big league game this year due to shoulder inflammation but has been one of the club’s most trusted relievers in recent years with a sterling 2.08 ERA and a strong 3.00 FIP in 117 innings of work since the start of the 2022 campaign, Grove, meanwhile, pitched to mixed results earlier this year before going down with a lat strain. The righty’s 5.06 ERA left much to be desired, but some of that lackluster run prevention seems to be due to unfortunate sequencing as demonstrated by his unusually low 62.5% strand rate and strong peripherals, including a 3.16 FIP, a strong 28.7% strikeout rate, and a fantastic 2.94 SIERA. Both hurlers should be welcome additions to the club’s bullpen when ready to return, possible sometime before the end of the month if their respective rehabs continue to go well.
