CHICAGO -- The return of left-hander Erik Bedard to the Mariners' starting rotation appears to be delayed yet again.
He hit another bump in the road in his last throwing session off flat ground and his penciled-in bullpen session at Safeco Field on Saturday has been postponed.
"He's doing OK, but I am sensing, from what I am hearing, that he is not as encouraged after his last outing [Sunday in Minneapolis] as he was his previous outing [Friday]," manager Jim Riggleman said. "I don't know, but it looks like throwing to a catcher on Saturday probably is backed up a little."
Bedard has been on the 15-day disabled list since July 5 with a tight left shoulder. He also was on the DL from April 9-24 with inflammation of his left hip.
When healthy, he has a 6-4 record and 3.64 ERA.
Asked if he was resigned to the possibility of Bedard missing the remainder of his first season with Seattle after being acquired from the Orioles for five players, Riggleman said, "I wouldn't say I am resigned, but I guess I look at it as being kind of a gravy if he does [return].
"I would love for him to pitch for us, so there is a feeling going into the winter on [how] he feels. But we can't make that happen."
Meanwhile, right-hander Brandon Morrow figures to rejoin the Mariners on Sept. 1 when rosters can be expanded. His conversion from reliever to starter at Triple-A Tacoma continues Thursday night with his third outing since being sent to the Rainiers on Aug. 5.
The reports so far are mixed.
"He's a work in progress and I'm sure he's feeling the difference between going three or four innings instead of one or 1 1/3," Riggleman said. "He's doing OK though. He went up to 60 pitches in his last outing and will be in the 70s [on Thursday.]
"I would say that he will go Thursday and at least one more after that."
