From Bruce Levine of Chicago’s 670 The Score comes word that the Cubs have activated catcher Welington Castillo from the 15-day disabled list and designated Eli Whiteside for assignment in a corresponding move to open up a roster spot.
Castillo wound up missing nearly three weeks with a rib cage injury. He was 3-for-10 with two walks during a two-game rehab assignment at Triple-A Iowa.
The 27-year-old backstop is batting .242/.287/.385 with five home runs and 21 RBI in 43 games this season for the last-place Cubs, who open play Sunday against the Pirates with a record of 31-41.
Whiteside, a .210/.265/.327 career hitter, will likely pass through waivers and head to Iowa.
