CINCINNATI -- The Cardinals began a road trip that could feature some significant roster churn by placing right-hander Sam Tuivailala on the 10-day disabled list with a left knee strain, raising the club's number of inactive bullpen arms to four.
Right-hander Mike Mayers, who made the club out of Spring Training but was recently optioned, was recalled from Triple-A Memphis in a corresponding move.
Tuivailala joins fellow relievers Ryan Sherriff (fractured toe), Luke Gregerson (strained left hamstring) and Brett Cecil (left shoulder strain) on the club's injury report after tweaking his knee during pregame stretches prior to Monday's 5-4 loss to Milwaukee.
