Cardinals: St. Louis placed struggling reliever Luke Gregerson on the 10-day disabled list with a right-shoulder impingement.
Gregerson, who signed an $11 million, two-year contract with St. Louis over the winter, has an 8.64 ERA in 12 appearances this season. The 34-year-old right-hander recorded just one out in Tuesday’s 4-1 loss at Minnesota and was charged with two runs and two hits.
St. Louis recalled righthander John Brebbia from Triple-A Memphis. Brebbia is 0-1 with a 2.70 ERA in six relief appearances for St. Louis this season, striking out 14 in 10 innings.
