PHOENIX — Arizona Diamondbacks right-hander Merrill Kelly was placed on the 15-day injured list Tuesday with right calf inflammation.
The 34-year-old Kelly has a 9-4 record with a 3.22 ERA so far this season, forming a formidable tandem with Zac Gallen at the top of the team’s rotation. Kelly’s move to the injured list is retroactive to Sunday.
The team also sent struggling reliever Joe Mantiply to Triple-A Reno. Mantiply was the team’s lone All-Star representative last season, but has spent much of this season on the injured list and has a 5.74 ERA in 13 appearances.
Arizona called up two right-handers - Kevin Ginkel and Justin Martinez - to take their places on the roster. The 21-year-old Martinez will be making his big league debut.
The D-backs came into Tuesday leading the NL West with a 47-32 record.
