The injured outfielder threw from 60 feet before Saturday's game vs. the Nationals for the second straight day.
"I'm feeling good," Crawford said. "I'm just taking it one day at a time."
He's working on a new throwing motion in an effort to keep his left elbow healthy. Crawford requested the club's help in changing his mechanics, and he is throwing with a late rotation of the upper body as opposed to the early rotation he once used.
"It's just to get the proper feel, make sure his body is in synch with his arm, and he looked very good doing it," said manager Bobby Valentine. "He played catch today and threw the ball well, ran the bases. He's progressing."
Crawford has not played in an organized game since last season ended. He took batting practice on Saturday, spraying the ball to all parts of the field.
Crawford's progression is ahead of fellow outfielder Jacoby Ellsbury, who is recovering from a separated shoulder.
Ellsbury hit off a tee for the sixth straight day on Saturday. He's throwing but is not ready to take live BP.
"He's felt great, he's in very good physical condition and his baseball activities are going to progress in this progression that we have him on," Valentine said. "He has had no setbacks."
Ellsbury has not played since his injury vs. the Rays on April 13.
