Nationals placed RHP Koda Glover on the 10-day disabled list with a left hip impingement.
Zach Britton is expected to begin a minor league rehab assignment with Double-A Bowie on Friday.
That's assuming Britton comes out of Wednesday's side session without issue. The Orioles have been taking their time with Britton, who has spent the last two weeks nursing a strained forearm. Interim closer Brad Brach has yet to allow a run in 10 outings this year, so the Orioles are in good hands either way.
Gary Sanchez (biceps) has been throwing from 120 feet.
He's also been taking BP in the batting cage. Sanchez will probably need a minor league rehab assignment before he's ready to return, but it shouldn't be long before the Yankees' star catcher is back behind the plate. The 24-year-old strained his biceps against the Orioles on April 8.
Didi Gregorius (shoulder) is on track to return against the Orioles this weekend.
Gregorius could be back as soon as Friday. The 27-year-old has looked sharp during his minor league rehab assignment, hitting .429 with a homer in four games for High-A Tampa. Gregorius has spent the past month recovering from a shoulder strain he suffered at the World Baseball Classic. Ronald Torreyes has been kept his seat warm at shortstop over the first few weeks.
Joey Rickard (finger) appeared in both games of Wednesday's doubleheader for Low-A Delmarva.
The Orioles didn't want to risk Rickard playing the field in poor weather conditions, so he served as the DH in both games. Rickard is expected to be activated from the disabled list Friday for the start of Baltimore's three-game series against the Yankees.
Tigers manager Brad Ausmus confirmed Jose Iglesias (concussion) will likely be activated from the 7-day disabled list on Thursday.
Iglesias took a knee to the head in a game against the Rays last Wednesday but only needed a week to recover. The 27-year-old has hit .267 with one home run and two steals in the early going.
Matt Barnes has dropped his appeal and will begin serving his four-game suspension on Wednesday.
It's probably the right call as MLB was unlikely to reduce his suspension. Barnes was banned for throwing at Manny Machado as retaliation for his hard slide on Dustin Pedroia last weekend. He'll be eligible to return Sunday against the Cubs. In his absence, Heath Hembree will handle setup work ahead of Craig Kimbrel.
Joe Mauer is not in the Twins' lineup Wednesday against the Rangers.
He'll get the night off with left-hander Cole Hamels throwing for Texas. Kennys Vargas is in at first base and batting fifth. Mauer carries a .236 average with no homers through 72 at-bats this season. He's no longer on the fantasy radar.
