Nationals starter Ross Detwiler has been sidelined for the last month due to a herniated disk in his lower back. Reports from a week and a half ago estimated the lefty may miss another month, leading to a late August return, but the latest from Adam Kilgore of the Washington Post suggests Detwiler may not return at all.
Detwiler visited specialist Robert Watkins Sr., a renowned back surgeon based in California, last month for a second opinion. Watkins diagnosed the herniated disk and prescribed a month of rest and anti-inflammatory medication.
By that point, Detwiler will not have pitched in about two months. The Nationals would place Detwiler on a full throwing program to rebuild his arm strength, “almost like you go through spring training again,” Johnson said.
Kilgore does add that the Nationals are still hoping to bring him back in September to see where he’s at, whether or not the team is still a contender in the NL East and Wild Card races. Before landing on the DL, Detwiler posted a 4.04 ERA in 71.1 innings over 13 starts.
In Detwiler’s absence, rookie Taylor Jordan has filled in admirably, compiling a 3.31 ERA in 35.1 innings over six starts.
Free agent right-hander Trevor Cahill reportedly has a one-year deal in place with the Athletics, according to MLB.com’s Jane Lee. The exact terms have yet to be disclosed, and as the agreement is still pending a physical, it has not been formally announced by the club.
Cahill, 30, is coming off of a decent, albeit underwhelming year with the Padres and Royals. He kicked off the 2017 season with a 4-3 record in 11 starts for the Padres, then split his time between the rotation and bullpen after a midseason trade to the Royals. By the end of the year, the righty led the league with 16 wild pitches and had racked up a 4.93 ERA, 4.8 BB/9 and 9.3 SO/9 in 84 innings for the two teams.
The A’s found themselves in desperate need of rotation depth this week after Jharel Cotton announced he’d miss the 2018 season to undergo Tommy John surgery. Right now, the team is considering some combination of Andrew Triggs, Daniel Gossett, Daniel Mengden and Paul Blackburn for the back end of the rotation — a mix that seems unlikely to change in the last two weeks before Opening Day, as Lee points out that Cahill won’t be ready to shoulder a full workload by then. Instead, he’s expected to begin the year in the bullpen and work his way up to a starting role, where the A’s hope he’ll replicate the All-Star numbers he produced with them back in 2010.
