Ross, who last pitched Sept. 13, has been undergoing treatment the last week for right arm soreness and fatigue. He's hopeful that he will pitch again this season.
Beginning Monday, the Padres have just seven games remaining in the regular season, starting with a three-game series at Petco Park against the Rockies.
Ross said Sunday morning that his arm feels better than it did a week ago when he first felt soreness following a start against the D-backs in Phoenix.
"It's getting better, I'm going through treatment and I'm feeling better," he said.
Does he think he might be able to slide back into the rotation for one more start, either this week at home or during a season-ending, four-game series against the Giants at AT&T Park?
"Maybe I can get one more [start], but we're trying to be smart with it," he said. "The emphasis is being smart with it and having it be good for 2015."
Ross said he's in daily communication with not only the athletic training staff but also manager Bud Black as he works through his treatment routine.
"The communication has been great," said Ross, who played catch Friday.
Ross is up to a career-high 195 2/3 innings this summer, 44 beyond his career high from 2012 (73 1/3 innings with Oakland, 78 1/3 innings for Triple-A Sacramento).
Black said Ross is pragmatic enough to realize that no amount of innings in the coming week will rate more important that having him healthy and ready to go for the start of Spring Training in February, ready to make 30-plus starts again.
"If Tyson can amass the same number of innings or more next year, it's more important than what he can get this week," Black said.
