Atlanta Braves third baseman Austin Riley will miss at least the rest of the regular season after breaking his right hand. Riley was struck Sunday by a 97 mph fastball from Los Angeles Angels starter Jack Kochanowicz in the first inning of Atlanta’s 3-1 victory. An MRI confirmed the fracture. The Braves said Monday that Riley will miss six to eight weeks, which knocks him out through the regular season and likely into the playoffs should the Braves qualify. The Braves have won six straight NL East titles, but that streak is in jeopardy after a rash of injuries. They trail Philadelphia by seven games.
