Colorado Rockies All-Star outfielder David Dahl is believed to have a right ankle sprain, the team announced after Friday's game against the San Francisco Giants in Denver, according to Yahoo Sports. Dahl was carted off the field in the top of the sixth inning after appearing to bend his right leg awkwardly as he tried to change direction to catch a line drive hit by Scooter Gennett, who was making his debut with the Giants. Dahl tried to plant his left foot to reach back for the ball, and while he made the catch, his right ankle buckled in the process.
