Zach Britton (forearm) played catch from 90 feet and threw some pitches off flat ground on Monday.
It was his first time throwing since an MRI on Friday ruled out structural damage. He said his arm felt good Monday, but more should be known about the next step after he talks to Buck Showalter and visits with a hand specialist. Brad Brach has been filling in at closer.
Chris Tillman (shoulder) is slated to throw around 75 pitches in his next rehab start Thursday for High-A Frederick.
Tillman allowed three runs over 3 2/3 innings Saturday in his second rehab start, but he said he felt better than his first. The hope is that he could be ready to be activated on May 2 against the Red Sox, but it depends on how things go on Thursday. The veteran right-hander has been dealing with shoulder issues since the offseason.
Dustin Pedroia (knee, ankle) is considered day-to-day after being examined Monday at Massachusetts General Hospital.
Good news for the Red Sox. Pedroia was spiked in the leg by Orioles third baseman Manny Machado on Friday and came down with soreness in his left knee and ankle, but it doesn't sound like he'll be sidelined much longer.
Pablo Sandoval (knee) will undergo an MRI on Monday.
Sandoval exited Sunday's game against the Orioles with what was termed as a right knee sprain. He was initially called day-to-day, but there should be more clarity on his status soon.
David Price (elbow) threw 45 pitches in a bullpen session on Monday.
Price got up and down three times to simulate breaks between innings. The veteran southpaw was recently slowed down a bit due to some soreness in his elbow, but appears to be past it now. Facing hitters should be the next step, but more should be known on Tuesday.
