From the St. Louis Post-Dispatch:

CINCINNATI — Left-hander Patrick “Packy” Naughton was acquired so late in spring training by the Cardinals that he didn’t have occasion to get into a spring training game before being sent out to Memphis. But Naughton’s brilliant start to his Class AAA season and a right hip impingement suffered by right-handed reliever Drew VerHagen Thursday night in Miami has brought Naughton to Great American Ball Park Friday.

... Naughton, who had struck out 12 in 10 innings, was called up to join the Cardinals’ 10-man bullpen for the start of a three-game series with the Cincinnati Reds.

Naughton, 26, who was claimed on waivers from the Los Angeles Angels on March 21, made five relief outings for Memphis, posting a 1-0 record with a 1.80 ERA and walking two. He pitched two innings or longer in four games.
