The Atlanta Braves have placed right-hander Spencer Strider on the 15-day injured list due to a strained right hamstring, following his season debut last week after recovering from elbow surgery. The injury occurred while he was playing catch before a game against the St. Louis Cardinals, and the Braves have recalled right-hander Michael Petersen from Triple-A as a corresponding move. Strider’s first start this season saw him allow two runs over five innings, and it’s unclear who will replace him for his scheduled Tuesday start as the Braves improve to an 8-6 record after a three-game sweep of the Minnesota Twins.
