Tom Koehler demoted to Triple-A; Hunter Cervenka recalled

The Marlins are shaking up their rotation once again, as the team announced that starting pitcher Tom Koehler was optioned to Triple-A New Orleans on Monday.

Miami is calling up reliever Hunter Cervenka to replace Koehler on the major league roster. The move comes one day after Koehler was rocked by the Cincinnati Reds on Sunday.

Koehler allowed five runs and nine hits in 5.2 innings pitched against Cincinnati. This is the second time this season that Koehler has been demoted to Triple-A.

This season, Koehler spent a substantial amount of time on the DL because of shoulder bursitis. Since his return, Koehler has recorded an ERA of 9.87 in four starts. For the season, the right-hander is 1-5 with an ERA of 7.92.

Cervenka has spent the entire season at Triple-A New Orleans.The reliever has posted a 4.50 ERA in 34.0 innings pitched. Cervenka was acquired by the Marlins from the Atlanta Braves last season.

Between the two teams, he compiled an ERA of 3.53 in 43.1 innings.

Cervenka joins Jarlin Garcia as the only lefties in the Marlins bullpen. The Marlins have not named a starter to take Koehler's place on Friday.
