Smith was scratched from the lineup ahead of Wednesday's game against Colorado due to right hand soreness.
Smith recently missed five games after getting hit on the hand by a pitch last Wednesday, and manager Dave Roberts has said that it will be something the 30-year-old backstop will have deal with for the rest of the season. While Smith takes a day off to nurse his hand, it will be Ben Rortvedt behind the plate catching for Blake Snell.
