Kontos (groin) played catch and threw off the slope of a mound Wednesday, Bill Brink of the Pittsburgh Post-Gazette reports.
Kontos was hoping for a minimal stay on the 10-day DL, but he's progressing a little slower than expected. The reliever is eligible to return from the disabled list whenever he's ready, but seeing as Wednesday was his first time throwing off the slope of a mound since landing on the disabled list, he'll need a little more time before rejoining the big-league bullpen.
