The Royals activated Brentz (hamstring) from the 15-day injured list Monday and optioned him to Double-A Northwest Arkansas, Anne Rogers of MLB.com reports.

The hamstring injury that landed Brentz on the IL before the season is no longer an issue, but what is a problem is the 17 walks he issued over six rehab innings. Brentz will stay in the minors to work on ironing out his command problems.

Yankees manager Aaron Boone said Monday that LeMahieu (foot) will be the team's primary third baseman when he returns, Gary Phillips of the New York Daily News reports.

LeMahieu will be eased into everyday duty, though, after missing so much time with a right foot injury. The veteran infielder is a couple games into the resumption of his rehab assignment and isn't expected to be activated for at least another week or so. Once LeMahieu returns, Oswaldo Cabrera and Jon Berti will fill utility roles.

Mountcastle is not in the lineup for Monday's game against the Cardinals.

Mountcastle is mired in a 1-for-20 slump and will sit Monday for the second time in Baltimore's past three games. Ryan O'Hearn will handle first base while Anthony Santander (knee) returns to the lineup as the designated hitter.

Cooper is out of the lineup for Monday's game against the Rays, Chris Cotillo of The Springfield Republican reports.

Cooper has an .860 OPS over his past nine contests but will head to the bench Monday for the second time in Boston's last three games. Connor Wong will rest his legs as the designated hitter while Reese McGuire receives a start behind the plate.

Rays manager Kevin Cash said Monday that he expects Eflin (back) to remain on the 15-day injured list for 2-to-4 weeks, Marc Topkin of the Tampa Bay Times reports.

Eflin landed on the IL on Monday with a lower-back injury that he felt crop up toward the end of his most recent start Saturday. The right-hander said it feels similar to an injury that cost him two weeks last season. While the hope is that the absence will be similar in length this time around, Eflin's manager has allowed for the possibility for it to be a bit longer.

Grissom is out of the lineup for Monday's game at Tampa Bay, Chris Cotillo of The Springfield Republican reports.

Grissom started the previous four games but will take a seat after going 2-for-15 during that stretch. David Hamilton will step in at the keystone and bat seventh in the series opener versus the Rays.

Polanco (hamstring) remains out of the lineup for Monday's game against the Yankees.

The Mariners have not yet made a roster move with Polanco, but he will miss a sixth straight start Monday with a right hamstring issue. Josh Rojas will handle second base while Luis Urias plays third base.

Crawford (oblique) will go through a pregame workout Monday before likely being activated from the injured list Tuesday, Ryan Divish of The Seattle Times reports.

Crawford is with the Mariners in New York and insists he's ready to go, but the club wants to see him get through a workout first before it brings him back. He's been out since late April with a Grade 1 right oblique strain. Dylan Moore is handling shortstop again for Seattle on Monday.

Jenkins (hamstring) will begin a rehab assignment Monday with the Twins' rookie-level Florida Complex League affiliate, Sam Dykstra of MiLB.com reports.

Jenkins made just one plate appearance for Single-A Fort Myers before straining his left hamstring and landing on the 7-day injured list. As one the top prospects in baseball heading into the season, Jenkins was thought to be in store for a brief pit stop at Fort Myers to begin the season before heading to High-A Cedar Rapids, but the injury could slow his ascent through the Twins' farm system.

Cole (elbow) will face hitters Tuesday, Meredith Marakovits of YES Network reports.

Cole has been throwing off a mound for a couple weeks and is now ready to face hitters for the first time since he was diagnosed with nerve irritation and edema in his right elbow back in mid-March. A rehab assignment shouldn't be too far down the road, although there's been no date revealed for that yet. Cole is still several weeks away from his season debut.
