Time is running out for Orioles right-hander Andrew Cashner to make a comeback this fall, and Roch Kubatko of MASNsports.com reports that he may not make it back to the mound before the regular season comes to a close next weekend. Cashner is still dealing with a lingering bout of bursitis in his left knee and was forced to miss his scheduled start against the Blue Jays on Monday. As no timetable has been given for his return to the rotation, it seems increasingly likely that he’ll be kept on the shelf until spring.

It’s been an up-and-down year for the 32-year-old righty, who has also missed some playing time after sustaining a neck strain and low back pain. After inking a two-year, $16 million deal with the Orioles back in February, he pitched to a 4-15 record in 28 starts with a career-worst 5.29 ERA, 3.8 BB/9, and 5.8 SO/9 through 153 innings. By the time he was sidelined with swelling and chronic pain in his knee, he’d already taken five straight losses, the last of which was an eight-run, one-strikeout affair against the Athletics that lasted only two innings.

The silver lining: It doesn’t look like Cashner’s knee problems will require any intensive treatment — he’s already received a cortisone injection to treat the problem areas — though there’s no reason for the Orioles to push him to make a quick recovery with the way their season is going. Following their 10-8 loss to the Yankees on Friday, the team will enter Saturday’s game with a 44-109 record, the worst in the majors.
