Reyes made his major league debut Tuesday, throwing a perfect ninth inning against the Reds with one strikeout.
Called upon to handle the ninth with the Cardinals down 7-4, Reyes retired the side in order on 11 pitches, eight of which went for strikes. The 21-year-old flashed the electric stuff that has made him one of the game's top pitching prospects, hitting 101 mph on the radar gun and pulling the string on a devastating curveball. Luke Weaver is reportedly in line to start Saturday -- he will replace Michael Wacha (shoulder) in the rotation -- and it's not clear when Reyes will make his first start, but it seems likely he'll get a chance to start at least a game or two before the end of the season.
