Smith (back) was placed on the 15-day disabled list Tuesday, Colleen Kane of the Chicago Tribune reports.

EDGE Analysis

Smith was slated to make his major league debut Monday, but was scratched prior to the game due to what was thought to be back spasms. It turns out that the catcher actually has sacroiliac joint dysfunction, which has a bit of a cloudy recovery time. There's a chance that he could come off the DL around the earliest date that he is eligible, but it could also sideline him for longer depending on how he feels further down the road. His status should become clearer as his rehab process moves along.

Doing himself favors with three hits, including two doubles, in seven Cactus League at-bats, the performance ultimately wasn't enough for Smith, who will provide organizational depth at catcher.
