Casas (ribs) said Wednesday in an interview on NESN that he should be cleared to swing a bat before the end of the week.

Advice: Casas noted earlier this week that he's still experiencing some discomfort in his ribs when he rotates, but the 24-year-old expects to progress enough in the coming days to try swinging a bat. It's too soon to say for sure when the first baseman might make it back since he still has some hoops to jump through, but Casas indicated in the interview that he's hoping to be activated from the 60-day injured list "right around July 1."

Murphy (elbow) is out of the lineup for Wednesday's game in Boston.

Advice: Murphy departed Tuesday's 8-3 win after being struck on the right elbow by a pitch. X-rays came back negative, and Justin Toscano of The Atlanta Journal-Constitution reports that the swelling on the elbow has mostly subsided. Murphy could be ready to go as soon as Thursday, but Travis d'Arnaud will fill in at catcher for Atlanta on Wednesday. Rotowire.com Today, 7:41 am

McKenzie came away with a no-decision in Tuesday's 8-5 win over the Royals, surrendering five runs on nine hits -- including three home runs -- and two walks over 5.1 innings. He struck out seven.

Advice: He was taken deep twice by Bobby Witt and once by Hunter Renfroe as McKenzie dug a 5-0 hole through four innings, but the Guardians were able to climb out of it. The right-hander's suddenly having trouble keeping the ball in the park -- after serving up only six homers over his first nine starts of the season, McKenzie's coughed up multiple long balls in three straight outings and has a 7.04 ERA over that stretch. He'll try to turn things around in his next trip to the mound, which is scheduled to come on the road this weekend in Miami. Rotowire.com Today, 7:28 am

Casas (ribs) still experiences pain when rotating and has not yet begun swinging a bat, Julian McWilliams of The Boston Globe reports.

Advice: Casas has been taking grounders and hitting the weight room, but that he's not yet swinging a bat suggests he may not return June 21, the earliest he can be activated off the 60-day injured list. "Whenever he feels better about it and he doesn't feel pain, then [swinging] is the next step," manager Alex Cora said. "It's not about treatment or whatever. It just kind of had to heal on its own." While Casas has been sidelined, the Red Sox are getting by with Dominic Smith and Garrett Cooper at first base. Rotowire.com Today, 5:05 am

Munoz has been dealing with a lower-back injury over the past few weeks and aggravated the injury during his collision with Oakland's Max Schuemann in Tuesday's 4-3 win, Daniel Kramer of MLB.com reports. He recorded two outs and was charged with one earned run on two hits en route to collecting his fourth hold of the season.

Advice: The initial concern following Munoz's removal from Tuesday's game was with his right ankle/leg, which seemed to get pinned underneath Schuemann, but the issue now appears to be linked to the closer's ongoing back problem. Manager Scott Servais said Munoz will head in for an MRI on Wednesday to determine the severity of his latest flareup, at which point the Mariners will likely make a decision on whether or not the 25-year-old righty will require a trip to the injured list. Should Munoz have to miss time, Ryne Stanek would likely be the next man up for saves. Rotowire.com Yesterday, 10:04 pm
