The Dodgers have long been expected to utilize a six-man rotation this year in order to accommodate Shohei Ohtani, and have accordingly assembled a deep group of arms. Last week, however, president of baseball operations Andrew Friedman revealed that, with Ohtani not expected to debut as a pitcher until sometime in May, the Dodgers intend to open the season with a five-man rotation. Four of those spots will go to Blake Snell, Yoshinobu Yamamoto, Tyler Glasnow, and Roki Sasaki. That fifth spot appears to be up for grabs, with the two leading candidates being a pair of arms that missed the 2024 season entirely due to injury: right-handers Dustin May and Tony Gonsolin.
The duo have been on very similar tracks for much of their respective careers. Drafted in the third and ninth rounds of the 2016 draft respectively, May and Gonsolin were both top-100 prospects for the Dodgers who made their big league debuts in 2019 and looked good in their brief cups of coffee. May posted a 3.63 ERA in 34 2/3 innings, while Gonsolin posted a 2.93 ERA in 40 innings. Both took on larger roles in 2020 and finished top-five in NL Rookie of the Year voting that year.
It was at the outset of the 2021 season where the pair’s careers begin to diverge. May has routinely been brilliant when healthy, but “when healthy” is a key caveat. May has started just 20 games and thrown 101 innings total over the past four seasons. That’s mostly been due to multiple elbow surgeries, and just when his arm looked to be healthy last summer, he suffered an esophageal tear that required surgery and sidelined him for 2024.
Gonsolin has been healthy long enough to build up a more sustained track record, but that playing time has come with ups and downs. In 2021, the righty posted a strong 3.23 ERA but a 4.54 FIP due in no small part to a bloated 14.2% walk rate. Gonsolin was sensational in 2022, logging a 2.14 ERA in 24 starts (130 1/3 innings) as he cut his walk rate by more than half and struck out a solid 23.9% of opponents faced. The success was short-lived. Gonsolin struggled badly across 20 starts in 2023 before undergoing his own Tommy John surgery, which wiped out his entire 2024 season.
May brings excellent rate stats to the table, with a 3.21 ERA (132 ERA+), a 3.59 FIP, and a 24.1% strikeout rate over that aforementioned stretch of 2020 starts between surgeries. He’s also just 27 years old. Between that youth and his limited on-field reps to this point in his career, it’s not outlandish to suggest that May could have a higher ceiling than even his strong career numbers suggest. Gonsolin has more experience pitching in big league games. The 31-year-old’s phenomenal 2022 season is also by far the best work either player has put forward in a given season. May has five-plus seasons of MLB service and can’t be optioned without his consent. Gonsolin will reach that same threshold 20 days into the season but for now has one minor league option left.
There are other candidates for the fifth spot, but none come close to matching the experience of May and Gonsolin. Bobby Miller is a former top prospect who delivered a strong 2023 season, but he was one of the worst pitchers in baseball last year. Landon Knack, Ben Casparius, and Justin Wrobleski are all healthy and available as depth starters after each debuted in 2024. Of the three, only Knack has substantial big league playing time under his belt. The 27-year-old’s 3.65 ERA in 69 innings last year could make him the next man up behind May and Gonsolin, but he still appears to be further down the depth chart than the two returning righties.
It’s worth reminding that franchise legend Clayton Kershaw is slated to start the season on the 60-day IL. Younger arms like Emmet Sheehan, Kyle Hurt and River Ryan are all recovering from Tommy John surgery performed during the 2024 season. Gavin Stone had shoulder surgery in October and isn’t likely to pitch this year. Fellow righty Nick Frasso is a well-regarded arm but isn’t likely to be in the Opening Day rotation mix after missing the 2024 season due to shoulder surgery performed last offseason. That length list of arms is a testament to the organization’s depth and also a good reminder that whoever opens the season as the No. 5 starter is hardly a lock to hold a rotation spot all season. The Dodgers will probably cycle through 12-plus starters this season.
Be that as it may, there’s plenty of intrigue surrounding the Opening Day staff. Assuming everyone remains healthy, how do MLBTR readers think the Dodgers’ fifth starter battle will play out? Will the club go for May’s upside and relative youth? Will they instead turn to Gonsolin’s more substantial MLB track record in hopes he can replicate his All-Star 2022 campaign? Will one of the less-experienced arms break out and claim the role? Have your say in the poll below:
