Two years ago, Felix Doubront annoyed the Red Sox by reporting to camp in less than optimal physical condition.

It has happened again.

Fresh off his first full season in the majors, Doubront arrived here last month and exhibited minor soreness in his shoulder. As a precaution, the 25-year-old left-hander has been held back from throwing off a mound, a step he finally may be cleared to take Wednesday.

“When he’s with us and we ask him to do stuff, he always does it with intensity,” general manager Ben Cherington said yesterday. “There’s plenty of time between now and Opening Day for him to do what he needs to do to put himself in position to be one of our starters and a guy we can rely on.”

Doubront splits the offseason between his native Venezuela and his home in South Carolina. He pitched a career-high 161 innings last season despite being shut down for two weeks in August because of fatigue, and said last week that he focused his winter workouts on strengthening his legs.
