The Albies injury (a left wrist fracture) was pretty unusual. The play was a runner (Michael Siani) attempting to steal second. The throw was to the 1st base side of the bag, by a good bit. Albies came off the bag and while reaching his glove to catch the ball, his glove got hung up on the runners shoulder. He'll be out @ eight weeks.
Fried's injury doesn't seem as bad, though arm injuries are always a concern with pitchers. He was placed on the 15-day injured list, retroactive to Thursday. The injury is reportedly a left forearm neuritis. The Braves' manager indicated Fried felt discomfort while stretching before pitching in the All-Star Game, and still felt it two days later, so they did a MRI on Friday. Snitker (the manager) indicated the MRI didn't show anything serious, so they're just putting him on the IR to give him a little rest until he's asymptomatic.
It's rare that a contending team doesn't suffer some injuries during the baseball season. That said, the Braves do seem to have suffered more than the average number of injuries, especially to key players.
