Ryan Brett (shoulder) will begin a rehab assignment with High-A Charlotte on Sunday.
Brett has been out for nearly a month with a subluxation of the left shoulder. He'll probably be sent down to Triple-A Durham once ready.
C.J. Riefenhauser (shoulder) will begin a rehab assignment with High-A Charlotte on Sunday.
Riefenhauser has been out the last month with a shoulder injury. He could be optioned to Triple-A once ready.
Victor Martinez will begin rehabbing his ailing left knee on Friday.
The Tigers put V-Mart on the disabled list earlier this week after he had another setback with his surgically-repaired knee. The Tigers haven't set a timetable for his return, but they'll proceed cautiously.
Charlie Morton (hip) will be activated from the disabled list to start on Monday against the Marlins.
Morton has been healthy for a while, but the Pirates wanted him to work on his mechanics as he made his way back from hip surgery. He appears to have accomplished that with a 1.33 ERA and 22 strikeouts over 20 1/3 innings during a rehab assignment. Vance Worley has been moved to the Pirates' bullpen.
Masahiro Tanaka (forearm, wrist) will throw 65 pitches in his next rehab start for Triple-A Scranton/Wilkes-Barre on Wednesday.
The Yankees aren't ruling out activating him from the disabled list after that, although it's possible they'll ask him to make an additional rehab start. Tanaka threw just 41 pitches over three scoreless innings on Thursday for Scranton/Wilkes-Barre in his first rehab outing.
Pablo Sandoval (knee) remained out of the Red Sox' lineup Friday.
Sandoval remains available to pinch hit, but his left knee remains too sore when making throws. He hopes to return to the lineup at some point this weekend. Brock Holt is at third base Friday.
Tanner Roark is expected to start either on Monday or Tuesday against the Cubs.
With Doug Fister (elbow) out indefinitely, it appears the Nationals are ready to move Roark back into the rotation. He hasn't pitched in five days, but he faced hitters on Friday and is expected to be able to get to 70 pitches during his start. The owner of a career 2.70 ERA over 36 starts, Roark should be scooped up in fantasy leagues where he remains unowned.
Justin Verlander (triceps) will throw a simulated game on Tuesday.
If that goes well, he should then be cleared to begin a rehab assignment. Verlander has been out all season with a strained right triceps but has progressed nicely the last couple weeks after resuming a throwing program. Still, he probably won't be activated until mid-June even in a best-case scenario.
