CLEVELAND — Matt Holliday has a sore back to go along with his aching bat.

New York’s slumping slugger was placed on the disabled list Sunday by the Yankees, who are hoping a week off will help his injury and maybe give him a chance to regroup at the plate.

The move with the designated hitter was expected after Holliday tweaked his back while swinging during Friday night’s 7-2 loss to the Indians.

He didn’t play in Saturday’s 2-1 win so he could get more treatment and be evaluated by the club’s medical staff.

The team described Holliday’s injury as a left lumbar strain.

New York sent rookie left-hander Jordan Montgomery to Triple-A after their game. Sunday.

The 24-year-old is 7-6 with a 4.05 ERA in 21 starts.

MARINERS-ATHLETICS TRADE: Seattle acquired All-Star first baseman Yonder Alonso from Oakland for minor league outfielder Boog Powell.

The Mariners, who have not been in postseason play since 2001, trail the Royals by 11/2 games for the second wild card spot.

Alonso, 30, is hitting .266 with 17 doubles, 22 home runs and 49 RBI.

He ranks second among American League first baseman with a .527 slugging percentage.

ROYALS: Kansas City put All-Star catcher Salvador Perez on the 10-day disabled list with a strain on the right side of his chest.

Perez was injured on a swing in the sixth inning Friday.

The five-time All-Star is hitting .278 with 21 home runs and 65 RBI.

“All of our core guys are really pretty indispensable,” Royals Manager Ned Yost said.

Cubs: Shortstop Addison Russell (strained right foot) thinks he will be able to return when he is eligible to come off the 10-day disabled list next Sunday.

Reds: Right-hander Scott Feldman was expected to start on Monday against the Padres, but has been pushed back a few days to give him more time to recover from a sore right knee.

Angels: Left-hander Andrew Heaney made a fifth rehab appearance and appears close to being activated.

Heaney had Tommy John surgery in July 2016 and was originally expected to miss this entire season.

Astros: Outfielder George Springer, who has been out since July 25 with a strained left quadriceps, has been improving and could come off the disabled list as soon as Tuesday.

Manager A.J. Hinch said Springer worked out on Sunday and would have a day off on Monday before resuming work on Tuesday when they could make a decision about whether to activate him.

Rangers: Right-handed pitcher Tyson Ross had a strong rehab start for Double-A Frisco on Saturday night, but Manager Jeff Bannister said it may be a little bit before he returns to the Rangers rotation.

Ross has been on the disabled list with a blister since July 24, but with two off days this week, the earliest he will return to the rotation is likely Aug. 14.

TIGERS: Left-handed pitcher Daniel Norris (groin strain) threw a bullpen session. He’s been on the DL since July 6.
