Michael Morse was on the verge of coming off the disabled list when he experienced pain while throwing on his minor-league rehab assignment and the news on the Nationals left fielder isn’t good.
General manager Mike Rizzo told reporters that Morse aggravated his torn lat muscle and will be in “total shutdown mode” for at least six weeks, adding that surgery is not an option to repair the injury.
That would still leave some time for Morse to potentially return before the All-Star break, but given his previous setback seeing him in the Nationals’ lineup before the second half seems unlikely. Morse is a huge loss, as he emerged as one of the league’s top hitters during the past two seasons while batting .298 with 31 homers and an .896 OPS in 163 games.
Calling up Bryce Harper from Triple-A to replace Morse isn’t a consideration according to Rizzo, so instead the Nationals will turn to some combination of Mark DeRosa, Xavier Nady, and Roger Bernadina in bigger roles.
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.
