Smith (elbow) threw a 20-pitch simulated game Wednesday, Pete Abraham of The Boston Globe reports.
Smith was initially scheduled to throw Tuesday, but was pushed back a day due to inclement weather. Abraham reported that Smith looked good during the session, but since he's more than a year removed from his last appearance in a game following May 2016 Tommy John surgery, the right-hander shouldn't be considered especially close to a return. He may need to pitch in another simulated game or two before the Red Sox clear him to head out on a minor-league rehab assignment, perhaps as soon as next week.
