Manager Brandon Hyde said after Sunday's 3-1 loss to the Blue Jays that Westburg was available for the contest only if an emergency situation had arisen, Matt Weyrich of The Baltimore Sun reports.

The 26-year-old's absence from the lineup was presumed to be a rest day, but there was apparently an unspecified issue that prevented him from taking the field. Westburg is expected to be back in the lineup Monday against the Red Sox, per Weyrich, so the infielder doesn't appear to be tending to a serious concern.

Polanco is out of the lineup for Sunday's game against the Athletics.

Dylan Moore will pick up a start at third base in place of Polanco, who occupied the hot corner for each of the Mariners' first three games of the season. Polanco recorded at least one hit in each of those contests, going 5-for-10 with a home run and three RBI.

Smith (quadricep) is out of the lineup for Sunday's game against the Red Sox.

Smith exited Saturday's contest after sustaining a quad contusion on a collision with the fence in foul territory, and he'll step out of the lineup for at least one game. According to Shawn McFarland of The Dallas Morning News, the Rangers are optimistic Smith will return to action Monday in Cincinnati. If he's cleared to play in the series opener versus the Reds, Smith could move into a full-time role at third base in the short term after Josh Jung (neck) was placed on the injured list Sunday.

Maton will start at designated hitter and bat leadoff in Sunday's game against the Angels.

Maton will serve as the White Sox's DH for the second day in a row, with both of those starts coming against right-handed pitching. At least until the White Sox get Josh Rojas (toe) or Mike Tauchman (hamstring) back from the injured list, Maton is getting a look as a strong-side platoon player.

Manager Stephen Vogt said imaging on Ramirez's right wrist came back negative, and the third baseman could be available as a pinch hitter Sunday against the Royals, Tim Stebbins of MLB.com reports.

The 32-year-old suffered a right wrist sprain on a slide while attempting to steal a base Saturday, but he's avoided a serious injury and may be available off the bench Sunday. Ramirez could return to the lineup as early as Monday in San Diego, though he could miss another day or two, with Vogt noting that the Guardians "want to be super cautious" so that the star third baseman's injury "doesn't turn into something that's going to linger."

Caminero is out of the lineup for Sunday's game against the Rockies, Ryan Bass of FanDuel Sports Network Sun reports.

Caminero went 4-for-9 with a double and a run scored in the first two games of the season but will hit the bench for Sunday's series finale. Jose Caballero will instead start at third base and bat seventh.

The Rangers recalled Ornelas from Triple-A Round Rock on Sunday, Shawn McFarland of The Dallas Morning News reports.

Texas will bring Ornelas aboard to provide some extra infield depth while Josh Jung (neck) is on the injured list. Jung's absence is unlikely to open up regular at-bats for Ornelas, as Josh Smith (quadricep) and Ezequiel Duran will be ahead of him on the depth chart at third base.

Westburg is out of the lineup for Sunday's game against the Blue Jays, Roch Kubatko of MASNSports.com reports.

He hasn't suffered any reported injuries through the Orioles' first three games, so manager Brandon Hyde seems to be giving the 26-year-old infielder a planned day off for the series finale in Toronto after Westburg went 6-for-13 with three solo home runs, a walk and an additional run to begin the season. Jackson Holliday will slide over from shortstop to fill in at second base.

The Rangers placed Jung (neck) on the 10-day injured list Sunday, Shawn McFarland of The Dallas Morning News reports.

Jung battled neck stiffness late in spring training, but he was cleared ahead of Opening Day and started in the Rangers' first two games, going 3-for-7 with an RBI. However, he was held out of the lineup for Saturday's 4-3 win over the Red Sox after the neck spasms cropped up again, and the Rangers have now decided to shut Jung down for a bit. Per Kennedi Landry of MLB.com, manager Bruce Bochy said that he's hoping Jung will need only a minimum-length stay on the shelf, so the 27-year-old third baseman could be back in action as soon as April 8.

Ramiriez (wrist) is not in the lineup for Sunday's game against the Royals, Tim Stebbins of MLB.com reports.

The third baseman suffered a sprained right wrist on a stolen-base attempt during the third inning Saturday, so it's not a surprise he'll be out of the starting nine for at least one game. Ramirez is undergoing additional testing and should be considered day-to-day in the meantime. Gabriel Arias will shift to the hot corner while Daniel Schneemann starts at second base in the series finale at Kansas City.
