Cards call up Tuivailala, send down Lyons
The Cardinals made one roster move on Sunday to address a need while hinting at another move to come.
With a bullpen that has been stretched to the max by a string of short starts, the Cardinals called up right-handed reliever Sam Tuivailala from Memphis and sent down Tyler Lyons, who started Saturday's game against the Tigers. Lyons lasted just 3 2/3 innings in the game. Lyons didn't go longer than five innings in any of his past three starts.
