Phillies right-hander Taijuan Walker was scratched from his spring start due to shoulder stiffness, manager Rob Thomson told reporters (including Matt Gelb of The Athletic). Scott Lauber of The Philadelphia Inquirer adds that Walker is set to undergo an MRI on the shoulder, while both note that right-hander Spencer Turnbull figures to open the season in the club’s rotation if Walker begins the season on the injured list. Walker isn’t the only Phillies pitcher dealing with injury troubles, as Todd Zolecki of MLB.com adds that right-hander Orion Kerkering is will begin the season on the injured list after missing time this spring due to illness.
The twin injury updates are tough news for Phillies fans. Walker was a solid back-of-the-rotation starter for the club last year with a roughly league average 4.38 ERA and 4.53 FIP, though he was durable enough to make 31 starts for the club last year and post 172 2/3 innings of work. Now, it seems likely that Walker will miss at least the first few weeks of the regular season, though it’s difficult to say how severe his injury is barring further updates from the Phillies.
Taking Walker’s place in the rotation should he begin the season on the shelf figures to be Turnbull, a former second-round pick who spent four years as a mid-to-back of the rotation starter with the Tigers. From his big league debut through the 2021 season, Turnbull posted a solid 4.25 ERA with an even strong 3.63 FIP. He was limited to just 54 appearances across those four seasons by injuries, however, including Tommy John surgery which limited him to nine starts in 2021 and sidelined him for the entire 2022 season.
Injury woes persisted through his return to the mound in 2023, as Turnbull struggled to a 7.26 ERA and 5.55 FIP across seven starts in the big leagues while battling neck and foot issues that caused a dispute regarding service time between Turnbull and the Tigers. Detroit eventually non-tendered Turnbull, at which point he signed with the Phillies on a big league deal. Turnbull appeared poised to begin the season as a long relief option out of the club’s bullpen, though he’s spent most of his career as a starter to this point and should have minimal trouble adjusting to the change in plans.
As for Kerkering, the soon-to-be 23-year-old right-hander made his Major League debut last season, allowing one run in three innings of work while striking out six of the fourteen batters he faced. That impressive cup of coffee earned Kerkering a role on the postseason roster in Philadelphia. He pitched 5 1/3 innings of work during the postseason against the Marlins, Braves and Diamondbacks, putting together a 3.38 ERA while striking out five and walking three.
Despite his minimal big league experience, Kerkering nonetheless had long been expected to be part of the club’s bullpen mix on Opening Day. That won’t come to fruition, however, as Kerkering will spend at least the first few weeks of the season on the shelf as he continues to prepare for the 2024 season. Kerkering’s absence, along with Turnbull’s likely move from the bullpen to the rotation, creates some level of uncertainty in the Philly bullpen. The Phillies acquired right-hander Zac Houston from the Rays earlier Saturday and he could join the likes of Connor Brogdon, Kolby Allard, Michael Mercado and Yunior Marte as possible options for the two bullpen spots previously expected to go to Kerkering and Turnbull.
