Manager John Farrell said that it'll be tough for Rodriguez (knee) to start the season on time if he doesn't pitch in a game in the next 10 days, Scott Lauber of ESPN reports.
Rodriguez progressed to throwing off flat ground Saturday, but he hasn't thrown off a mound yet. The left-hander appears to be in line for a rotation spot after pitching well in 21 starts with the Red Sox last season, but Opening Day could be in jeopardy for him if this knee issue continues to linger. He's already a bit behind the rest of the pitchers, and with plenty of other options in the Red Sox system, it is important for the southpaw to get back to action as soon as possible.
