Gray (toe) will throw against batters Wednesday, Nick Groke of the Denver Post reports.
Since being pulled from a game less than a week ago with a toe injury, the club has reported that Gray's health has significantly improved. He's slated to throw 80-90 pitches against Rockies minor leaguers Wednesday. There's yet to be any word regarding his availability for the start of the season, but more information should be available following Wednesday's workout.
