Jason Hammel, who has lost four straight starts trying to pitch with a sore right knee, will undergo surgery and miss at least three weeks, Dan Connolly of the Baltimore Sun reports.
Hammel has loose cartilage floating around in the knee that he needs taken out.
“Where it was before it was kind of uncomfortable,” Hammel said. “Now it is kind of in the joint, kind of pinned into the joint, so every time I bend the knee it pretty much hits the nerve in the area, so it’s not very comfortable right now.”
Hammel nearly made the AL All-Star team after opening the season 8-2 with a 2.61 ERA, but he’s given up 17 runs in 19 2/3 innings in his last four outings, all of them losses.
The Orioles haven’t announced who will replace him in the rotation, but Tommy Hunter appears to be the likely choice. Even though Brian Matusz pitched a shutout in his first start after being sent down to Triple-A Norfolk, manager Buck Showalter isn’t keen on the idea of bringing him back so quickly.
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.
