Here's a roundup of the latest injury news across the Majors:
A.J. Pollock, D-backs
After seeing a hand specialist Tuesday, the D-back star center fielder was revealed to have suffered an avulsion fracture in his left thumb and will miss four to eight weeks, per an official announcement from the D-backs. Jarrod Dyson and Chris Owings are expected to fill in for Pollock in center field during his absence.
Arizona called up infielder Christian Walker from Triple-A Reno on Tuesday to correspond with Pollock's trip to the DL.
Pollock injured his thumb while diving for a ball during the ninth inning of Arizona's 7-2 loss to the Brewers on Monday night. He was putting together an MVP-caliber season to this point, leading the NL with a .620 slugging percentage and belting 11 home runs with 33 runs driven in over his first 40 games. More >
Joey Votto, Reds
The star first baseman was held out of Cincinnati's lineup Tuesday due to tightness in his lower back. Votto is listed as day to day, and Adam Duvall took his spot at first base for the Reds' matchup with the Giants.
Votto left Monday night's 10-7 loss to San Francisco before the bottom of the fourth inning after he appeared to be laboring while running the bases the inning prior. More >
Adrian Beltre, Rangers
Texas placed Beltre on the 10-day disabled list Tuesday with a left hamstring strain after the star third baseman re-aggravated the area in Sunday's series finale against the Astros. Beltre is expected to miss at least two weeks as he hopes to fully recuperate.
"Rough, because I didn't feel any setback. I didn't feel the hamstring at all," Beltre told MLB.com on Sunday. "I was trying to protect it the whole time, because I knew it would take me a little longer. Tried not to run hard any play. … Disappointed, obviously, but nothing I can do now." More >
Edwin Encarnacion, Indians
Manager Terry Francona held Encarnacion out of the Tribe's lineup Tuesday because the slugger was dealing with stiffness in his neck and upper back. Encarnacion's situation is seen as day to day.
Encarnacion has gotten off to a slow start to 2018, batting .205, but he has hit nine home runs over 146 at-bats.
Yoenis Cespedes, Mets
An MRI revealed Tuesday that Cespedes is dealing with a mild strain of his right hip flexor, and the Mets placed the outfielder on the disabled list Wednesday morning. The Mets initially listed Cespedes' ailment as a quad issue. The move to the DL is retroactive to Monday, and Cespedes will be eligible to return May 24.
Bradley Zimmer, Indians
After some deliberation, Cleveland decided to place its talented center fielder on the 10-day disabled list with a left rib contusion. Zimmer has been dealing with pain since he crashed into the center-field wall at Yankee Stadium on May 5 while trying to make a difficult catch. He has also been dealing with a sore left shoulder in the wake of that violent collision, though his rib has proven more problematic -- particularly when swinging the bat.
Cleveland was able to place Zimmer on the DL retroactive to May 12, meaning he would be eligible for activation as early as next Tuesday when the Indians open a two-game set at Wrigley Field against the Cubs. More >
Adam Eaton, Nationals
Washington's sparkplug told reporters Tuesday that he expects to return to the Nationals' active roster in six weeks as he continues to recuperate from arthroscopic surgery on his left ankle. Eaton underwent the surgery last Thursday.
The 29-year old Eaton has been on the disabled list since April 11 and was moved to the 60-day DL on May 11.
