Castillo will start behind the plate and serve as the White Sox's cleanup hitter Sunday against the Mariners.

EDGE Analysis

With the left-handed Wade LeBlanc on the mound for Seattle, the White Sox will drop Yonder Alonso down in the order from his usual No. 4 spot to make room in the heart of the lineup for the right-handed Castillo. The move up in the order could make Castillo a more interesting option in DFS contests than he normally might be.

Castillo is not starting Saturday against Seattle.

EDGE Analysis

The White Sox continue to alternate their catchers, with James McCann taking his turn in Saturday's contest. Expect Castillo back in the lineup Sunday if the pattern continues.

Castillo is out of the lineup for Wednesday's game against the Indians, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

The White Sox haven't cleared Castillo to start consecutive games while he continues to manage a lower-back issue, so he'll check out of the lineup in the series finale after catching Monday's game. James McCann steps in behind the plate in Castillo's stead.

Castillo has a lower-back issue that prevents him from catching on consecutive days, Daryl Van Schouwen of the Chicago Sun-Times reports.

EDGE Analysis

This explains why James McCann has started two of the first three games, including Lucas Giolito's gem of a start Sunday. Castillo played the second game of the season Saturday, going 1-for-3 with a walk.

Castillo is on the bench for the second time in three games Sunday against the Royals.

EDGE Analysis

Castillo was the presumed starter for the White Sox throughout drat season, but it's been James McCann in an apparent starting role through the first three games of the season. It's an odd decision, as Castillo's career 100 wRC+ is far better than McCann's 75, and neither has a particularly strong reputation as a pitch framer. It may take some time to see if Castillo is truly headed for a backup role or if the pair is set for more of a 50-50 split.

Castillo will start at catcher and bat seventh Saturday against the Royals, Scot Gregor of the Chicago Daily Herald reports.

EDGE Analysis

The White Sox surprisingly went with James McCann behind the dish in Thursday's season opener, but that may have just been a result of manager Rick Renteria wanting to use the backstop as a personal catcher for southpaw Carlos Rodon. Castillo will check into the starting nine and is still expected to see the bulk of the action at catcher in 2019.

Castillo is out of the lineup for Thursday's season opener against the Royals, Joel Goldberg of FOX Sports Kansas City reports.

EDGE Analysis

Castillo looked like a good bet to break camp as the White Sox's top backstop, but that's suddenly more of a question mark with James McCann behind the plate for the opener. McCann was the better performer of the two at the dish this spring, so it's possible manager Rick Renteria is just riding the hotter bat for Opening Day. It could also just be a situation where Renteria wants McCann to act as the personal catcher for starting pitcher Carlos Rodon.

Castillo (back) will start at catcher and bat fifth in Saturday's Cactus League game against the Dodgers, Scott Merkin of MLB.com reports.

EDGE Analysis

Castillo will make his first spring appearance in a week after getting some time off to tend to a sore back. The backstop had already logged 22 plate appearances prior to the temporary shutdown, so he should be ready to pick up the start behind the plate in the White Sox's regular-season opener March 28 in Kansas City.

Castillo is currently sidelined with a sore back, James Fegan of The Athletic reports.

EDGE Analysis

The issue doesn't sound like it will keep Castillo sidelined for too long. The backstop is slated to get some at-bats in a minor-league game Friday before returning to Cactus League action Saturday against the Dodgers. Barring any setbacks, Castillo should be ready to go for the start of the season.

Castillo went 2-for-4 with a home run, a double, two RBI and two runs scored Friday against the Angels.

EDGE Analysis

Castillo clubbed a two-run blast over the wall in center in the fourth inning, his first of spring training. The 31-year-old backstop is now batting .294 with a home run, four RBI and two runs scored in camp.
