Socolovich was demoted to Triple-A Memphis on Sunday.
The Cardinals were in need of a spot on the 25-man roster for Sunday's starter, Mike Mayers, and Socolovich appears to be the odd man out. Given that it's a spot start for Mayers, it's quite possible Socolovich's trip to the minors will be a short one.
Morrison (wrist) is out of the lineup Sunday against the Athletics, Marc Topkin of the Tampa Bay Times reports.
The Rays will hold Morrison out for his sixth straight game while he battles a right wrist injury, enabling Steve Pearce to slot in at first base. With Tampa off the schedule Monday, Morrison will have a little extra time to help with his recovery, but it's still uncertain if he'll be available for Tuesday's series opener with the Dodgers.
Maybin is out of the lineup Sunday against the White Sox.
Maybin was actually on the field earlier in the day for when the Tigers and White Sox resumed play of Saturday's game, which was postponed with the score tied in the ninth inning due to rain. He officially finished that contest with two hits, two runs and two stolen bases across his four at-bats, marking another excellent performance for the outfielder. He'll be rewarded with a rest for Sunday's originally scheduled game, but could still be used a pinch-hitter or defensive replacement.
McCann will start at catcher Sunday against the White Sox and bat eighth in the lineup.
Though McCann is behind the plate for Sunday's game, he had sat out the previous three contests in favor of Jarrod Saltalamacchia. McCann has followed up a promising rookie year with a dud of season in 2016, slashing just .197/.245/.303 across 205 plate appearances. Until he turns a corner offensively, he may have to settle for a timeshare at catcher with Saltalamacchia.
Saltalamacchia is out of the lineup Sunday against the White Sox.
Saltalamacchia was behind the plate when the Tigers and White Sox resumed Saturday's suspended game earlier Sunday, but he'll have off for the initially scheduled contest. James McCann steps in to spell Saltalamacchia, who had started the previous three games behind the plate.
