After allowing five base runners to the San Francisco Giants on Monday, the baseball world wondered if San Diego Padres' left-hander Clayton Richard was totally healthy. He was removed after five scoreless innings with shoulder discomfort, which was later diagnosed as a strain. From Tim Sullivan of the San Diego Union-Tribune:
Padres put Clayton Richard on disabled list with a strained left shoulder. Reliever Luke Gregerson returns to the active roster.
Richard was having a mediocre year, his 3.88 as much the product of his home ballpark as anything else. His strikeout rate had dropped precipitously this season, so a shoulder issue is less than surprising.
There's no word on whom the Padres will go with in the rotation during Richard's absence, though Wade LeBlanc is on the 40-man roster, made 25 starts for the Padres last year, and has been making starts for Tucson in Triple-A.
Gregerson has a 2.63 ERA for the Padres in 27-1/3 innings this year, which gives him the 12th-best ERA in the Padres' bullpen.
