ST. LOUIS — The Cardinals are swapping one lefty reliever for another.
The team announced on Thursday they had activated reliever Andrew Miller (toe) from the 10-day Injured List and in a corresponding move designated reliever Tyler Webb for assignment.
Webb had a 13.22 ERA in 16 1/3 innings this season for the Cardinals, walking 19 and allowing 22 hits. In four years with the Cardinals, Webb had a 4.57 ERA in 106 1/3 innings.
In 7 1/3 innings this year, Miller has an 8.59 ERA, eight strikeouts and four walks.
The Cardinals begin a four-game series with the Reds on Thursday night at Busch Stadium.
