(BaseballStL) -- The St. Louis Cardinals added fresher arms to the bullpen ahead of a doubleheader against the Pittsburgh Pirates on Tuesday.
The team promoted right-handed relievers Michael Blazek and Keith Butler to the big league roster and sent down Fernando Salas and Marc Rzepczynski, who combined to throw 55 pitches and allowed five runs over three innings in a 9-2 loss on Monday, to Triple-A Memphis.
Blazek, 24, has appeared in four games in his first two stints with the Cardinals this season. Butler, 24, posted a 1.98 ERA in 12 games for St. Louis in his previous stint with the team this year.
Tyler Lyons, 25, was also added to the team’s roster to make his seventh start of the year for St. Louis in the second game of the doubleheader. He posted a 2-3 record with a 5.51 ERA in the previous six starts. Since being sent down to Memphis in June, Lyons posted a 4-0 record with a 1.65 ERA in six starts.
Lyons will be able to serve as the 26th player under the league’s rules for roster expansion during a doubleheader.
