The Padres scratched Joe Musgrove from Wednesday's scheduled start due to right shoulder soreness and could miss more than six days
The Padres did send left-hander Tim Hill (finger sprain) to the injured list amid a bevy of moves, while catcher Brent Sullivan was optioned to Triple-A El Paso and right-hander Brent Honeywell was designated for assignment
Newly-acquired first baseman/designated hitter Ji Man Choi was placed on the active roster as was infielder Garrett Cooper and right-hander Scott Barlow. All three were acquired before the trade deadline. Left-hander Ray Kerr was recalled from El Paso
Padres manager Bob Melvin said Musgrove has been pitching through discomfort
"He's been experiencing a little bit of shoulder stiffness the last couple starts," Melvin said. "He has been pitching through it. At this point in time we just don't want it to get any worse. Typically in the season you go through stuff like this. He has been pitching a lot recently. Hopefully we can get ahead of this.
Fellow right-hander Nick Martinez (4-4, 3.93 ERA) replaced Musgrove in a spot start for the series finale at Colorado on Wednesday afternoon
