Rodriguez (knee) executed a round of agility and cardiovascular drills on the field Tuesday, Chad Jennings of the Boston Herald reports.
Rordiguez has been throwing bullpen sessions for a week now but the Red Sox wanted him to get on the field and execute some change-of-direction and participate in pitcher's fielding practice. The left-hander came through it just fine is in line to face live batters Saturday. That puts him on schedule to begin a rehabilitation assignment by the middle or late part of next week.
