Ruiz is out of the lineup for Wednesday's game against the Red Sox.
Ruiz had started the previous four games, going 0-for-8 with a 1:6 BB:K while reaching base on two hit-by-pitches. Three of those starts came against left-handed pitching, and Ruiz looks as though he could mainly be limited to a short-side platoon role in the wake of Kyle Stowers' return from the injured list Monday.
