Trumbo is sitting out of Friday's contest due to back spasms, Roch Kubatko of MASN reports.

EDGE Analysis

Trumbo apparently gets bouts of back spasms every now and then, so there's a decent chance that this won't keep him out of the lineup for very long. That being said, back injuries can be a bit finicky at times, so the slugger's status for the rest of the weekend's games is worth monitoring. Consider him day-to-day for the time being.
